1 Project SWAMP Research project funded by ERA-net Road collaboration Oslo Knud A. Pihl SWAMP Coordinator

2 My presentation General background Important words in the proposal Result for road owners Milestones Project organisation

3 General background Adaptation of climate change is on the agenda world wide Water is on the top of the hierarchy of elements which tease the road owners Changes in rain events (extreme shower and more rainfall throughout the year) are the main reasons Rise of sea level and ground water level are other reasons

6 General background SWAMP - Storm WAter prevention - Methods to Predict damage from the water stream in and near road pavements in lowland areas is our project Danish Road Institute (DRI), Denmark and Swedish National Road and Transport Research Institute (VTI), Sweden Coordinator is DRI

7 Important words in the proposal New knowledge: Earlier methods on the basis of previous precipitation (statistics) In the future regional predictions of e.g. precipitation, evaporation given in selected IPCC scenario

8 Important words in the proposal Work smarter: upgrading the drainage system in a optimum way find the most exposed places, called blue spots carried out in the best manner money can be saved by tailormade solutions

9 Results for road owners Guidelines for development of a model for blue spot identification Description of a model, not the model itself Use of Geographical information system (GIS) for presentation Data of predicted rainfall, drain systems, topography, soil etc. Can be used to order a system to be developed

10 Results for road owners Guidelines for reducing vulnerability to flooding in local places Check conditions and maintenance Point out improvements, extensions and renovations Checklist and step by step guidelines Can be used immediately by road owners

11 Results for road owners Report: Existing literature related to SWAMP project List of total literature used in the project Summaries of important conclusions Can be us immediately by the road owners and others

12 Milestones Contract, Preparing the project in detail after discussion with the Project Steering Group (PSG) Climate change input gathered, Collection of metrological knowledge and data relevant for the project. Study of IPCC scenarios and data from meteorological institutes

13 Milestones Interviews at local sites local people finished, Interview primarily with Swedish and Danish professionals about local spots where flooding events had occurred in the latest

14 Milestones Blue spot models on GIS ready, Collection of GIS-models and other knowledge and data relevant for the project. Study of knowledge, models and data from institutes and firms. Literature state of the art report, preliminary version, Literature search and rapport in a preliminary version

17 SWAMP Work Package 3 GIS Model for blue spots Digital maps and data. Michael Larsen Road Directorate, Danish Road Institute

18 GIS Model Consist of a large number of digital maps and layers. GIS is only the presentation of data! The Model is the database and the calculation behind the presentation (not the goal for this project) An example of dataset and GIS (presentation) from Denmark

19 Dataset and authorities in Denmark: 1 Road, road alignment, tunnels, junctions viaducts, bridges (Danish Road Directorate, DRD) Natural water system, sensitivity of habitats, environmental data, catchment area (National Environment Research Institute (NERI) and Miljøportalen.dk) Geological, groundwater table, geotechnical (De Nationale Geologiske Undersøgelser for Danmark og Grønland, GEUS) Topsoil, hill slope, lowland and wetland (Faculty of Agricultural Sciences).

20 Dataset and authorities in Denmark: 2 Topography, elevation, areas with critical slopes, basic for calculation of the catchments area (The National Survey and Cadastre) Maps of hydraulic, natural and man made aquifers, digital plans of road drainage systems, digital plans of land use drainage system (Local authorities and local road administration) Meteorological data from WP2 (DMI in Denmark, SMHI in Sweden) Other relevant maps, found during the work in SWAMP.

22 Main road system

23 Detailed look

24 + Streams and lakes

25 +Buildings and houses

26 + Topography (2,5 meter contour spacing)

27 New elevation model New national digital elevation model has been made by laser scanning. Elevation model with contour spacing of 0,25-0,5 meter. Even the smallest catchment area can be calculated.

28 Eriksvolde, one of the largest middle age castle i Denmark

29 3 levels of analysis 3 different prices Level 1: Screening by topography All blue spots are identified by setting the permeability=0. Level 2: Risk analysis How often is this happening? In 10, 25, 50 and 100 years. Level 3: Connection between surface and drainage system. Run off from surface and discharge from drainage system are complied.

30 Case study from the city of Odense Complied by PH Consult Level 1: Screening by topography Level 3: Run off, discharge and drainage.

31 Screening of a larger area Compiled by Orbicon

32 Thank you for your attention

33 SWAMP WP4 Maintenance & Repair Fredrik Hellman Swedish National Road and Transport Research Institute

34 Background» Climate change will induce more extreme weather in the future» heavier rain in shorter time» increased risk for flooding of roads and infrastructure Gothenburg (Mölndal) after heavy rain in December 2006

35 Objective of WP4» Find critical factors that control flooding of roads» Find information about inspection, maintenance and repair to prevent flooding» Find guidelines how to prevent flooding of roads

36 How to do it» Literature study» Questionnaire» assemble experience from professionals working with drainage and flooding» Identify manuals or working procedure for inspection maintenance and repair» Interviews

37 Deliverables» Report» literature survey» critical factors» Guidelines» suggestions about maintenance, improvement, renovation and inspections

38 Questionnaire» For this project it is very important to get information through the questionnaire» Please, help us to get the answers!» The aim is 3-4 professionals/country Netherland Sweden Norway Ireland Denmark England Germany 3 replies 0 replies coming soon 1 replies 1 replies 3 replies 1 reply 3 replies
