2 FOREWORD A little over four years ago, Ron Thiemann called me. He had two guys in his office with an improbable tale, and wanted to know if I was interested. The two gentlemen in question, Guus Stelling and Wytze Schuurmans, claimed that they could make water calculations a hundred times faster. A highly unusual claim, which would need solid proof to back it up. There would then also have to be people who dared to try it. After hearing what they had to say, I contacted my colleague Luc Kohsiek and we decided to go ahead. Pier Vellinga and Bas Verkerk soon came to help us, and so it all began. We may not always have been able to follow everything that Guus told us, but his enthusiasm was infectious and the results were spectacular. Last year, the municipalities of Amsterdam, Rotterdam, The Hague and the OAS (wastewater system optimisation) project De Groote Lucht decided that wastewater also deserved a spot in 3Di. The Valoriasation Programme Delta Technology supported 3Di as a prime example of innovation that yielded a usable market product. We are now rounding off a unique innovation project that is bringing in new ideas both scientifically and on many other fronts. Above all, there is now something that is usable for all water and wastewater managers. I hope that you will become as convinced as I am and that you will dare to pick up the gauntlet. Michiel van Haersma Buma, Chairman of the 3Di watermanagement steering committee Delft, 20 March

4 MODELLING WILL NEVER BE THE SAME AGAIN Can you still remember your record collection? Or, for the younger generation, your CD collection? You may well have kept everything, but your music is now probably stored in digital form and you listen to it not only in the living room, but also en route in a car or while doing sports. Your music collection is less tangible, but you can enjoy it more often. And what about your water system models? Do you have models of your water system? If so, where do you keep them? And if you want to do calculations on them, do you have to involve a department or consultancy firm? How many days or weeks is it then before you get an answer? Simple modelling, with easy access to your data and being able to see the results of your calculations almost at once. This may sound like pie in the sky but, thanks to 3Di, it is already a reality. 3Di models are stored centrally in the cloud and will never get lost. A sophisticated version control system means that your earlier versions are also retained. Calculations can be handled easily through your Internet browser. You will have an answer to your question in just a few minutes. Planning officers and spatial planners as well as water specialists can use 3Di to get a clear picture of their interventions in water and spatial planning and quite literally map out what the effects of these plans will be on watermanagement. You still have all your records or CDs, but now you listen to your music as digital files, at home or in the car or while jogging. Your music collection is less tangible, but you can enjoy it more often. 4 5

5 AUTOMATING MODELLING 2014 will be a watershed in modelling, just as 1908 was for car production. Although cars had been around for some time, this was when the automobile became available to the masses, thanks to the mass production methods of the famous Model T-Ford. 3Di watermanagement is not only quick at the calculations: area models are also put together rapidly by means of a computerised production technique. A large group of experts with backgrounds in database techniques, GIS expertise, (groundwater) hydrology and hydraulics are working closely together on an automated computer environment. This improves the quality of the 3Di area models, as well as making them more maintainable and of course cheaper. This means that every water board and any municipality can now afford 3Di area models will be a watershed in modelling, just as 1908 was for car production. 6 7

6 FREQUENTLY ASKED QUESTIONS This section discusses a number of questions that are often asked during workshops and presentations. What is 3Di? What exactly can it do? What is its relationship with the modelling packages? Is 3Di an open system? And what is Stichting 3Di, the 3Di Foundation? What is 3Di? 3Di comprises a number of innovative, interrelated developments. These allow 3Di to make water calculations interactively as a whole, performing calculations in the cloud and visualising the results realistically on an ipad or touch table, as well as using 3D stereo visualisation. The so-called area models act as a kind of underlay in 3Di, made up of various cartographic layers of geographical information, such as the soil type, ground level height and ground usage. The 3Di calculation core can then carry out water calculations on this underlay. 3Di generates these area models automatically as far as possible from the source files. The high level of detail, the ultrafast calculation times and the interactive access via a web browser make the area models suitable for a broad target group, varying from water specialists, spatial planners, operational managers and communications advisers through to disaster coordinators. What can 3Di do? Thanks to the 3Di sub-grid technique, flooding and high water can be calculated in fine detail. A realistic visualisation of the calculation results in the digital terrain height model then makes the calculations clear for laymen. 3Di area models can quite literally map out water flows and the effects of flooding, heavy precipitation and drought, both for the current situation for example during heavy rainfall and for climatological scenarios in urban and rural environments. The users can play interactively with 3Di, altering the map that is used for the calculations. These could for example be modifications in the external situation, for example in terms of ground levels, urban expansion, permeability, type of road surfacing, etc. 8 9

7 The layout and transport capacities of water, sewer and groundwater systems can also be altered, for instance by changing the flow profiles and the civil engineering structures. The combination of high calculation speeds and the fine level of detail of the external areas in the model mean that 3Di is an excellent tool for decision support in crisis management, interactive planning processes and investment decisions. The effects of possible interventions can be visualised in next to no time, providing maximum support for the evaluations. The high level of detail also means that laymen can recognise the situation and non-specialist users are also able to come up with ideas and try them out. Additionally, the advanced GIS environment gives specialists the capability to make much larger numbers of changes behind the scenes. What is the relationship between 3Di and modelling packages? 3Di is an instrument for exploring measures for improvement that could be taken in outside areas. It is ideal for questions about how water can be given a place in spatial planning, crisis management and the local approaches to dealing with high water. It is not intended to replace modelling packages for designing and testing water and wastewater systems. 3Di focuses primarily on policy officers at water boards, managers of external areas, planning specialists, urban planners, disaster coordinators and other water safety professionals. Unlike the specialised modelling packages, 3Di works with predefined area models in which the user can implement measures in the outside areas or the water system, for instance through a user-friendly interface, in order to get a picture of the effects. What is Stichting 3Di, the 3Di Foundation? 3Di has been developed over the course of the last four years by a consortium of Deltares, Delft Technical University and Nelen & Schuurmans. The development was made financially possible by the following water boards, municipalities and subsidy providers: Delfland Water Board, Hollands Noorderkwartier Water Board, Municipality of Rotterdam, Municipality of The Hague, Waternet, OAS De Groote Lucht, Kennis voor Klimaat and Waterkader Haaglanden. 3Di area models are integrated right into the heart of the calculations. This means there is no time-consuming exchange of data in files, giving very fast calculation times as a result. The models also include all interactions, so that the effects of measures can be examined very precisely. 3Di is a highly successful co-operative venture in the so-called Golden Triangle. Topclass specialists and developers in IT, hydraulics and GIS systems are working together for 3Di in a small team. The inspirational and efficient way in which this is being done and the exceptionally good cooperation with those working in the field are essential 10 11

8 aspects. The foundation called Stichting 3Di was set up to ensure this approach remains possible in the future and to enable successful further development. This foundation manages 3Di and is working on further development of 3Di. In concrete terms, Stichting 3Di develops and manages area models and supports continued development of 3Di. The board of the foundation consists of representatives of the consortium members and water managers. The board determines the top-level of vision and defines an annual development plan in consultation with the Programme Board. The bodies funding the continued development can join the Supervisory Board, which monitors the administration and running of the foundation. There is also a Programme Board consisting of experts in the fields, who draw up the development plan. In addition, there is a user community. The users who take part in this provide details of their experiences with 3Di and draw up wish-lists for further development. 3Di is open and transparent. As a 3Di user, you will be involved with the 3Di Foundation for the one-off creation of one or more area models and the hosting and management of the area models and 3Di calculations servers. A charge is made for this, clearly linked to water system characteristics (see overview at the back). The income that the Foundation receives from the users covers the costs of the area models plus cloud services such as hosting and storage. In addition, there is an ongoing search for subsidies to support new 3Di developments. How can I join? You can start using 3Di and support its continued development. If you use 3Di, you will be supporting the 3Di Foundation and you can take part in the 3Di user community. This meets twice a year and issues advice about desired modifications and expansions based on practical experience with 3Di. The 3Di pilot phase has been completed and the implementation of 3Di has been started in the areas managed by the Delfland and Hollands Noorderkwartier water boards. Water is only one of the spatial structures in spatial planning. It must therefore be possible to display water information combined with other relevant information. 3Di provides this capability, which therefore makes it ideal for developing structural visions and climate adaptation strategies. New fields of application are naturally also being explored, such as integration of e.g. water quality and dyke strength. Partners who support any new developments financially or who have knowledge or technology that might be interesting can join 3Di and help define the direction in which it will develop. 3Di is an open development in that sense too

9 Is 3Di open? 3Di is a fully open development. The substantive background (how 3Di works) has been published in scientific journals, articles in professional magazines and tutorials on the website Progress over recent years has been exhaustively tested in workshops and practically oriented studies, an approach that has hugely benefited the quality of 3Di. A number of graduate students are also actively involved with elements of 3Di. Those who are interested are always welcome to visit the 3Di lab at Drieharingstraat 6 in Utrecht, where they can discuss content-related aspects with the programmers and modellers. The formats and the structure of the input and output files of the calculation core are fully open and accessible; the interface has been published. An area model is developed as a one-off by the 3Di Foundation and placed in the cloud. This means that the quality and problem-free functioning can be guaranteed in the cloud. Users can then make whatever changes they want using open GIS models. The links with universities and colleges come clearly to the fore in joint projects. By applying 3Di in graduate and doctoral studies, the 3Di Academy maintains contacts with the scientific staff, graduates and university students. The partners in 3Di want to make 3Di into open source software. A number of development and validation stages are still required for that. The software components that have been developed will be published under a GPLv3 licence (open source). By doing so, we are making it possible for other parties to develop new functionality and add it to 3Di. New functions are assessed and, if found suitable, will be included in new releases after thorough testing. The calculation core for flooding is expected to be published under GPLv3 within a year.

10 A LOOK UNDER THE HOOD OF 3Di General 3Di is a dynamic water model. The water movements in 3Di are described using two laws of conservation, namely conservation of mass and conservation of momentum. One special feature of 3Di is that conservation of mass is handled extremely strictly, as accurately as the machine precision will allow. The momentum equation describes the water movements in accordance with the Saint-Venant equations as 1D and 2D flows. The groundwater flow in 3Di is described using the Darcy equation. The moisture in the soil is described using CAPSIM. All the equations are put into a matrix which is efficiently solved implicitly so that calculations can be performed using larger time intervals without stability issues. This also implies complete interaction between 1D, 2D, groundwater and sewerage. A 3Di area model can consist of one or several model layers, namely: a raster terrain layer (for flooding and precipitation) a raster subsoil layer (for soil moisture content and groundwater) a 1D open water network layer (for the canal system) a 1D sewer network layer (for the sewer system) Raster terrain layer, for flooding and precipitation The 2D flows in 3Di are suitable for flooding and for the flows in lakes and estuaries. The 2D flows are entirely hydrodynamic and suitable for dry bed flow. The calculations make accurate allowances for detailed height differences in the landscape (or the ground, thanks to these sub-grid technique with irregular quadtrees. This also allows rivers and canals in the sub-grid raster to be excavated. A 3Di area model can be made up of multiple layers. This example is a model with three layers: a raster subsoil layer, a raster terrain layer and a 1D open water network layer. It is possible to include 1D levees in the scheme to give a more accurate picture. The 1D levees can be modified over the course of time, for example to simulate the growth of 16 17

11 1 hour a breach. Precipitation and evaporation can be input as well as flooding. In principle, the precipitation uses weather radar images, but it is also possible to add precipitation from weather stations. The calculation core can use more than one billion sub-grid cells and can perform the calculations about 1000 times faster than comparable models on the same hardware configuration. Wind effects are also going to be added. Raster subsoil layer, for soil moisture content and groundwater 12 hours The groundwater flow is restricted to shallow groundwater in the unsaturated zone. The unsaturated zone describes a variety of processes such as evaporation (e.g. through crops), infiltration, percolation, storage, drying and capillary rising. The soil properties are specified per sub-grid and the soil moisture content is calculated per sub-grid. 24 hours The groundwater flow between calculation cells is described in two dimensions using the Darcy equation. Seepage and infiltration are specified spatially. High groundwater levels result in water on the surface. The groundwater flows then become two-dimensional surface flows. The deep groundwater flow is not included in 3Di. 1d open water network layer The 1D flow through canals is calculated fully hydrodynamically. A profile can be given for the canals showing resistance and bed height. Civil engineering structures in the canals can be modelled, including pumping stations, weirs, underflows, culverts and bridges. Flows at civil engineering structures make allowances for the direction of flow and various flow conditions, such as free and submerged flows. Real-time control of these structures is possible, although that is still custom work at the moment. Compared to other 1D models, 3Di conserves mass completely, avoiding calculation time steps needing to be shortened even when canals dry out or in supercritical flows. There are three variants for the linkage between 1D and 2D flows: embedded, connected and isolated. There are three ways of connecting the 1D canals up to the groundwater. This allows any system to be described properly. The rainfall runoff process is described in 3Di using these linkages, with slow removal via the groundwater and rapid removal via surface flows. Example of a test calculation working out how the groundwater level will progress

12 1D sewer network layer The calculation core is capable of handling the sewer system fully hydrodynamically right down to the sewer pit and drain level. Underground constructions can be described in detail using storage height functions. Civil engineering structures may be included in the sewer network, such as pumping stations, weirs and underflows. Just like the 1D open water network, the sewer network can be linked to the 2D raster network and the 2D groundwater network. The same type of connections are used for this as for the 1D surface waters, i.e. embedded, connected and isolated. The sewer layer calculation conserves mass completely, does the calculations without time step reduction and is suitable for both subcritical and supercritical flows.

Calculations down to the level of storm drains are then feasible. The zoom level determines which details are shown

13 MANAGING AND USING 3Di AREA MODELS General A great deal of attention was paid in the setup of 3Di to creating and managing model schematics, also known as area models. The key points are: connecting to the source control files of the water manager flexible updating of the area models with new data checking, correcting and adding the necessary data processing and modifying area models by the modeller or consultant version control of the area models and model scenarios interactive use of the area models Control at the source Every water manager has source data and the corresponding software for managing data about waterways, sewers and civil engineering objects. When an area model is produced, data standards are used along with standard management software. The data that is required for the area model is read into an object database and a raster database. Changes to the source files can be read in again later into these databases. Checks, corrections and additions The object database is checked, with corrections and additions being made as necessary. These checks are fully automated, which makes them extremely flexibly when updates are needed. The corrections and additions are needed for making the area model. The supplementary and adjusted values are also reported back to the manager of the source The level of detail of 3Di makes it possible to make detailed calculations of high water problems and find tailored solutions for them

14 files. The managers can then make their own decisions as to whether or not the changes should be implemented in the source files. Data mining The checks are carried out at two levels. The basic checks ensure that the model is complete. An optional detailed check can be performed, based on big data mining. This involved correction and supplementation of missing profiles, connections, culverts, weirs and level limits, using numerous source files. Data mining turns out to be particularly useful for secondary and tertiary water systems, yielding better quality area models. Creating an area model The area models are generated automatically from the object database and the raster database by a 3Di specialist. The object database and the area models are stored in the cloud. All the variants of an area model are managed automatically in the cloud and it is possible to retrieve older variants. Updating an area model Area models are stored in a SpatiaLite database. The user can download and edit an area model and then upload it again. Editing is done using QGIS v2.2. All raster data and object data in the area model can be accessed and edited using standard GIS tools. 3Di area models can be modified by the specialist right down to the finest level of detail using QGIS, an open source GIS package

15 Interactive use When a calculation is to be carried out, the user has a 3Di web interface for choosing an area model and a scenario. The user can start up a calculation with the play button and follow the calculation on the map as it progresses. During the calculation, the user can retrieve information and make changes. These modification may relate to the spatial planning or the water and wastewater systems and civil engineering structures. 3Di and FEWS OIn order to validate area models and to use them in a high water prediction system, there are links with FEWS and ControlNext. In this combination, the 3Di area model is updated every 15 or 60 minutes with the latest radar data and predictions. Discrepancies between the values measured and calculated are logged and can be adjusted if so desired. In 3Di area models, the 1D watercourses are fully integrated into the 2D flow model. Visualisation of the culverts, weirs, pumping stations (rotating impellers for pumping stations removing water) and the water flow (a stream of white balls ) quickly provide insights into how the water system works

16 3Di IN PRACTICE 3Di area models can be used for numerous applications. Various practical case studies have been carried out over the last few years. A 3Di area model can be used for a desktop study, as an interactive tool in workshops and as part of a system for fire brigade support or high water prediction. Alternatives can be input immediately during working sessions and the effects calculated. Consensus is achieved much more rapidly this way about the usefulness and necessity of measures, making a distinction between those that are sensible and those that are pointless. We have listed a number of applications below for illustrative purposes. Getting 3Di properly embedded in your organisation obviously needs more than just a properly functioning model. Thanks to the 3Di cloud solution, the technical implementation has been made as simple as possible, at any rate. Disaster management A 3Di area model is ideal for use in an emergency or in a disaster exercise. When an actual or impending breach is signalled, it can be entered into the area model instantaneously. Within just a few minutes, a realistic picture of the flooding is available. A 3Di area model can also be used for flooding problems due to extreme precipitation. This can also use weather radar images to get an accurate spatial picture. Emergency measures can be tried out first in the area model. The effects of raising dykes, emergency pumping or closures of waterways, cycle tunnels and viaducts can be presented in just a few minutes. This makes 3Di the perfect tool for helping take the correct emergency measures. The pictures can be shared using the watch function of the Internet interface. Images can also be sent to the Disaster Management System. A good picture of the current situation is crucial in an actual or impending emergency, as is a picture of the consequences of any actions that might be taken. Using a 3Di area model makes it possible to estimate which roads could still be used for evacuation if the water retention structures fail

17 Classification of embankments Regional embankments and areas with variable water levels are standardised by the provincial authorities into so-called (Dutch) IPO classes (1 to 5). These provincial classes are related to the damage that would occur if the embankment broke. The high level of detail in the 3Di area models allows the calculation of the damage to be made much more accurately. Tens of thousands of dyke breach scenarios can be calculated in just a short time with 3Di, allowing the correct IPO classes to be determined for each section. This let the Hollands Noorderkwartier water authority save over a hundred million euros on proposed dyke reinforcement work. Thanks to the more accurate classification, unnecessary dyke strengthening work as a result of excessively high classifications can be avoided. Rivers and estuaries 2D models of rivers and estuaries have been around for a long time, but they are too slow or too large for many applications. The new 3Di calculation core means that it is now possible to do 2D calculations. Putting the outer flood fields underwater or draining them again and how this affects water transport by the river are described exceptionally well in a 3Di area model. The 3Di area model also allows the effects of deeper dredging, harbour expansions and bypasses to be examined. The effects of nature development in the flood fields or the utilisation of overflow areas can be made clear to everyone. 3Di has been used abroad to make 2D models of Jamaica Bay in New York and San Francisco Bay. The calculation time for these models is just a few minutes, although the models contain a billion cells. Tackling water problems The 3Di calculation schema is suitable for calculating 2D flow patterns in rivers because appropriate allowances are made for the effects of floodable field areas. Water problems as a result of heavy precipitation have led many water authorities to test their water systems. The Dutch National Administrative Agreement on Water standards state that the vulnerable areas, such as urban areas, need greater protection than the less vulnerable areas such as grasslands

18 A 3Di area model allows the impact of extreme precipitation to be mapped out very accurately at a fine level of detail. A 3Di case study carried out in Delfland showed that the water burden in a vulnerable polder could be reduced by eighty per cent. That is a massive difference and it generated correspondingly substantial savings. Instead of having to purchase land for water storage in the open, a tailored solution is now being realised together with the municipality that fits in with the spatial planning. Determining the water burden and looking for tailored solutions is many times quicker and more accurate with 3Di area models than was previously possible. Urban environment plans New environmental legislation is on the way, creating a need for integral spatial analysis of water behaviour. Extreme precipitation can involve vastly more rainwater on the streets than the bui08 standard scenario. If you are interested in what would happen in your municipality if 100mm of rain were to fall in one go, a water scan can be carried out using a 3Di area model. For Amsterdam, for instance, a 3Di area model has been made down to the level of paving stones. This area model has allowed the vulnerable areas in the city to be mapped out accurately. Optimising urban drainage systems (UDS) An optimisation study (also known as an OAS) can be carried out for UDS. A 3Di area model is particularly well suited for obtaining a good picture of how the UDS actually functions. A model such as this contains the entire sewer system of all municipalities down to the individual pipes, combined with a 3Di surface model. A 3Di area model has been developed for the OAS De Groote Lucht. This has allowed the functioning of the UDS to be examined accurately, including studies of optimisation measures such as disconnecting residential areas, real-time control and alterations to the sewer system or the wastewater purification. The ability of areas (particularly urban areas) to handle climate issues can be examined, including looking at severe extremes of precipitation, alone or combined with dyke breaches. 3Di brings climate scans within reach for any water authority or municipality

19 WHAT WILL IT COST? You now know what 3Di is worth. But what will it cost to use it? This chapter gives a picture of the pricing, with a number of worked examples at the end. The costs can be subdivided into: Annual usage costs for calculations with a 3Di area model. One-off costs for creating one or more 3Di area models. The costs of realistic three-dimensional stereo visualisation. The prices stated below are exclusive of Dutch VAT. Users can make any desired modification to an area model and analyse scenarios or measures that could be taken. This is done using the basic area model and your calculation subscription. 3Di usage costs You do not have to purchase a licence and you hardly need to install any software yourself in order to do calculations with 3Di. The 3Di calculation core is hosted on calculation servers in a professional data centre. To perform calculations with a 3Di area model, you need a modern Internet browser such as Chrome and a 3Di subscription. The approach is similar to a package for a mobile phone: you purchase a 3Di package that gives an annual amount of calculation time and data storage. TYPE STORAGE CPU TIME PRICE BASIS 5 GB 10 HOURS L5.000 MEDIUM 50 GB 100 HOURS L LARGE 500 GB 1000 HOURS L PREMIUM 2 TB 2000 HOURS L The 3Di calculation core can show flow velocities at the sub-grid level. This was capable of giving a detailed picture of the changing flow patterns at high and low tide in San Francisco Bay, for example. Where would escaped prisoners from Alcatraz have made landfall? 3Di has the answers

20 The calculation times are quick enough that the Basic package is sufficient for occasional use. The Medium package is more suitable for a medium-sized municipality. A water authority with numerous 3Di area models should find Large to be enough. Premium is the best option for intensive, large-scale use. Multiple users can work with a single account. You can also give external consultants access to your account. Every user is a registered and can be granted more or fewer rights. If you want to work with multiple users at the same time, then you will need to extend your subscription. The extended subscription can be a smaller type. There are discounts that apply to equivalent subscriptions; these also apply to multiple models. For operationally critical applications, such as when used in a disaster organisation or as part of a decision support system, a higher service level agreement may be needed. This can be sent to you on request. 3Di area models You need a 3Di area model if you are going to work with 3Di. A 3Di area model can consist of one or several model layers, namely: a raster terrain layer (for flooding and precipitation) a raster subsoil layer (for soil moisture content and groundwater) a 1D open water network layer (for the canal system) a 1D sewer network layer (for the sewer system) The basic area model can only be made by the 3Di Foundation. Once an area model has been created, it may be modified by everyone who has the appropriate rights. The one-off costs of an area model are determined by the number of model layers and the number of schema elements per model layer. The costs can be worked out using the table on page 37.
