Hanssen Projectbeschrijving Maaivelddaling Subject Delft University of Technology Department of Geoscience and Remote Sensing Faculty of Civil Engineering and Geosciences Aan: Dhr. S Riemersma Hoogheemraadschap van Delfland Postbus DB Delft Geachte heer Riemersma, In vervolg op onze plannen voor een promotie (PhD) onderzoek naar maaivelddaling stuur ik u bijgaand een gedetailleerd projectplan. In uw van 20 maart j.l. liet u mij weten dat uw collega Peter Hollanders dit onderzoeksvoorstel heeft besproken in de innovatiegroep van Delfland en de portefeuillehouder heeft geïnformeerd, en dat Delfland in principe euro per jaar (voor een reguliere PhDperiode van vier jaar) wil bijdragen aan dit onderzoek. Daarna heb ik het op mij genomen om een medefinancier te zoeken om dit onderzoek mogelijk te maken. Zoals ik u eerder per mail heb laten weten is dit gelukt, en is Rijkswaterstaat bereid om een bijdrage van euro per jaar te leveren. Met bijgaand Plan van Aanpak (projectplan), zou dan D&H de aanvraag kunnen goedkeuren om het project te kunnen starten. U gaf daarbij aan dat het belangrijk is het project voor 1 juni 2015 te starten. Ik hoop dat bijgaand projectplan de goedkeuring kan krijgen van D&H, en dat Hoogheemraadschap Delfland, Rijkswaterstaat, en TU Delft een volgende stap kunnen zetten in het inzetten van innovatieve methodes om de beheersproblematiek van maaivelddaling aan te pakken. Met vriendelijke groet, Prof.dr.ir. Ramon F. Hanssen Antoni van Leeuwenhoek hoogleraar Afdelingsvoorzitter Department of Geoscience and Remote Sensing PS. Ten overvloede memoreer ik nog dat we onlangs een voorstel hebben gedaan bij de Technologiestichting STW (de zogenaamde Water-call ) om te proberen dit onderzoek breder in te bedden. In dat voorstel zou bijvoorbeeld ook onderzoek kunnen worden gedaan naar de efficiënte monitoring van waterkeringen. Indien dit STW voorstel zou worden gehonoreerd, zou het onderliggende project hier integraal in kunnen worden ingebed, waardoor Delfland ook zou kunnen profiteren van dit bredere onderzoek door officieel deel te nemen in de gebruikersgroep.

Combined with rising sea levels, this affects the lives of more than a billion people on earth. Elevation change can be a consequence of geophysical processes as well as anthropogenic activities. To predict elevation change using physical predictive models, accurate geodetic observations are indispensable. Geodetic networks consisting of well-defined benchmarks have been established in many areas, and terrestrial and spaceborne techniques such as InSAR deliver relevant information. However, the wide-scale and precise motion of pasture on (drained) peat soils cannot be measured with geodetic techniques yet, due to the absence of identifiable points for repeated measurements. Yet, peat soils are particularly susceptible to subsidence when cultivated. As a result, elevation changes are unknown, and long-term sustainability in relation to flooding risks, as well as water table management, is sub-optimal.
3 Page/of 3/17 In this project we will develop, test, and deploy a method for the direct estimation of elevation changes of pasture on drained peat-soils in the Netherlands, starting in the management area of Hoogheemraadschap Delfland, particularly using spaceborne InSAR. We will build upon recent advances in the estimation of surface motion over low-coherence areas, using the combination of all available SAR data and a new spatio-temporal estimation method. The project will produce surface elevation change maps over the areas of interest, which will be combined within the larger effort to establish a Dynamic-DEM, in relation to flood management. Moreover, the elevation change maps will improve drainage and water table management, enabling more sustainable agriculture, and limiting excessive greenhouse gas fluxes. Dutch management abstract De hoogte van land in laaggelegen kustgebieden, zoals Nederland, is niet constant. In combinatie met zeespiegelstijging beïnvloedt dit het leven van meer dan een miljard mensen op aarde. Hoogteveranderingen worden veroorzaakt door natuurlijke effecten, maar ook door menselijk handelen, zoals bijvoorbeeld de bemaling van polders. Om ook de hoogteligging in de toekomst middels modellen te kunnen voorspellen zijn nauwkeurige metingen van hoogteverandering cruciaal. Hiervoor worden geodetische netwerken aangelegd, bestaand uit goed identificeerbare merkpunten (zoals waterpasbouten). Daarnaast leveren zowel terrestrische als vliegtuig- en satelliettechnieken relevante informatie. Echter, op dit moment is het onmogelijk om de hoogteverandering van weide- en akkerbouwgebieden te meten met geodetische technieken, simpelweg doordat het in dit soort gebieden niet mogelijk is om representatieve merkpunten aan te brengen: op een graspol kun je niet met millimeter-precisie meten. Als gevolg hiervan kennen we de werkelijke hoogteverandering dus nauwelijks, waardoor miljarden-beslissingen over infrastructuur en waterveiligheid een empirisch fundament missen, maar waardoor ook overstromingsmodellen suboptimaal zijn, en waterschappen hun beleid slecht kunnen onderbouwen. In dit onderzoek ontwikkelen en testen we een methode om hoogteverandering in het veenweidegebied, met name het beheersgebied van Hoogheemraadschap Delfland met hoge precisie te meten, middels satelliet radartechnologie. Een recente voorstudie toonde aan dat dit mogelijk is door alle beschikbare satellietdata te combineren in een nieuw ruimte-tijdmodel. Hiermee kunnen bodembewegingskaarten gemaakt worden, die uiteindelijk zullen worden gecombineerd in een dynamisch hoogtemodel. Dit leidt tot betere overstromingsmodellen, het duurzaam beheren van het karakteristieke Nederlandse veenweidegebied in relatie tot landbouw en ecologie, en tot de beperking van uitstoot van broeikasgassen. Historical background of the project Much of the western part of the Netherlands is covered with pasture on drained peat soils (Langeveld et al, 1997), see Figure 1. Peat is composed of organic materials which oxidize and emit greenhouse gases when exposed to the air (Bartlett and Harriss, 1993; Van Huissteden et al., 2006). Peat oxidation contributes for 1-3% of the annual greenhouse gas (GHG) emissions of the Netherlands (Van den Bos, 2003): Peat soils with a subsidence rate of 10 mm/y equate to an emission of about 22 tons of CO2 per hectare/y (Van den Akker et al., 2008).
4 Page/of 4/17 Oxidation of peat soils results in volume reduction and subsequent subsidence. As a result, the thickness of the vadose zone decreases, as the land surface gets closer to the phreatic zone or groundwater level. Figure 1 (A) Typical example of pasture on drained peat soils. (B) Spatial variability of cumulative subsidence over a period of 37 years. (Van den Akker, 2005) Consequently, to keep the land sufficiently dry to be used as pasture, the soil needs to be drained, resulting in an increased vadose zone thickness, in more oxidation, and therefore more subsidence. In addition to oxidation, the peat soils are consolidating when drained, as the weight of the increased thickness of the vadose zone increases the effective stress of the saturated peat. Peat consolidation generally occurs on time scales of decades, whereas peat oxidation continues until the peat soils have disappeared completely (Van Asselen et al., 2009). Many parts of these regions are currently situated below sea level and are expected to subside significantly in the coming decades. Subsidence rates in drained peat soils in the western Netherlands are believed to range from 0.2 to 5.1 cm/y, with common values between 0.5 to 1.5 cm/y (Baas, 2001). However, most quantitative subsidence rates reported in literature are either modeling results, or results from few mechanical point measurements using a local in situ device (Van den Akker, 2005). Moreover, subsidence rates are not constant in time and space (Schothorst, 1977; Stouthamer et al. 2008). Periodic geodetic estimates, with high precision and proper quality description, available with contiguous spatial sampling over all areas of interest are not available. First indications of seasonal deformation caused by the change of the groundwater level between the seasons (low in summer and high in winter) from remote sensing were observed by Van Leijen and Hanssen, (2008) and Cuenca and Hanssen, Measuring wide-scale subsidence rates in pasture on drained peat soils is difficult, if not impossible, with conventional geodetic methods as soft soils make it impossible to install fixed benchmarks for repeated terrestrial surveying. The local roughness of the pasture is in the order of a decimeter, and changes continuously due to grazing cattle. Returning to the same location for a repeated precise height measurement is nearly impossible, but even if it was feasible, the local effects of grass and cattle may be even higher than the signal of interest. This makes precise terrestrial geodetic point measurements over large areas impossible.
5 Page/of 5/17 Airborne laser altimetry (lidar) is able to determine the elevation of the pasture areas. The quality of the lidar-derived elevation estimates (the AHN-2 digital elevation model) is expected to be better than 5 cm in terms of the systematic offset (bias) and better than 5 cm in terms of stochastic error (dispersion). When two lidar surveys acquired with a certain time difference are differenced to estimate subsidence, these quality metric imply that, with a 5% level of significance, a difference of 14 cm will be detected with a 50% likelihood. Additionally, this calculation ignores (i) the repeatability of the measurements (measuring the same locations in the pasture), (ii) the two systematic offsets, (iii) the footprint width of the lidar, relative to the roughness of the terrain. In other words, it is not possible to estimate subsidence from repeated lidar surveys, unless the deformation signal is in the order of a decimeter (hence, long time intervals), or unless it is allowed to perform spatial averaging over large areas under the assumption that the averaged area is flat. InSAR and InSAR time series approaches such as Persistent Scatterer Interferometry (PSI) or Small Baseline Subsets (SBAS) are able to detect millimeter level elevation changes as relative double-differences in space and time (Hanssen, 2001). However, conventional InSAR cannot maintain coherence due to the very fast temporal decorrelation in the area (te Brake et al., 2012). The absence of coherent point scatterers prohibits the use of PSI, and even when buildings are found in the area, it is likely that their deformation will not be representative of the subsidence in the center of pasture fields (Cuenca and Hanssen, 2008). Goals and objectives Given the problem description above we want to develop a methodology to provide reliable empirical estimates of current shallow subsidence processes, using satellite remote sensing, particularly pasture in peat-rich areas. Recent preparatory studies by Morishita and Hanssen (2014,2015) have demonstrated that observing such processes is feasible by combining data from several satellite missions and by applying an innovative data processing methodology. Moreover, these first results show that subsidence rates may be a factor 2-3 greater than previously expected, and are very spatially variable, stressing the importance of better empirical observations. To reach this goal, we need (i) to develop better radar processing methods, exploit new satellite missions, and combine information over time series data now archived. Additionally, since the estimated shallow subsidence observed cannot be validated, we will (ii) study the driving mechanisms behind the shallow subsidence, and (iii) perform additional in situ measurements using a SET (Surface Elevation Table), a portable mechanical leveling device for measuring the relative elevation change of wetland sediments. Specific scientific significance and innovative aspects The main innovative aspect of this project is the fact that we will measure something which has been unmeasurable until now: the subsidence of pasture land. The main significance of the project is that, if successful, for the first time subsidence of pasture in areas below sea level will be established from empirical data, instead of physical models or sparse point measurements. Since expectations on (and knowledge of) land motion are driving investments of billions of euros1 for decades to come in the Netherlands, it is crucial that policy decisions can be based on empirical information. 1 the Delta program will cost billion euro/year until 2050, and billion euro/year from
6 Page/of 6/17 In terms of innovation, the contributing factors are (i) the algorithmic approach, (ii) the (spaceborne) multi-sensor approach, and (iii) the link with in situ data and modelling. The algorithmic approach will be based on three pillars. First, the underlying idea is to use all available SAR data over the area of interest, optimizing for coherence per land unit, rather than for radar image resolution cells. The second pillar is that we start with parametric models to describe the land motion, including long term velocities as well as seasonal variability. The third pillar is to trade spatial resolution for noise reduction, acknowledging the difficult coherence conditions for InSAR over pasture. Until recently, it was uncertain whether this approach would be successful, but recent results in a demonstration project (Morishita and Hanssen, 2014, 2015) over a small test area show the feasibility of the approach. The second innovative aspect is the spaceborne multi-sensor approach. We use X-, C-, and L-band data in a weighted approach, and exploit the optimal characteristics of each sensor in terms of repeat interval, resolution, and wavelength-dependent decorrelation rates. Most importantly, we expect a fundamental improvement by using the Sentinel-1a and -1b time series which will become available starting early The third innovative aspect is the fact that we will not only produce results from satellite data processing, but we will perform in-situ validation using terrestrial measurements, linking the expertise of partner institutes such as Utrecht and Wageningen University and Deltares, and update existing subsidence models. In terms of significance and relevance, this research relates to (i) land subsidence in relation to flood risk, (ii) sustainability of agriculture in the Dutch pasture lands, (iii) assessment and control of greenhouse gas emission rates, (iv) water management, (v) ecological long term planning. The relation of land subsidence with flood risk (i) is evident. It should be stressed here that changes in predicted subsidence rates in the order of millimetres per year have dramatic consequences for the water storage capacity (WCS) of the area. To compute the WCS, the (extra) subsidence should be multiplied with an area that can be many tens of square kilometres, which leads to very large volumetric amounts. Thus, flood prediction models need to be adjusted if subsidence values are not as expected. The sustainability of agriculture (ii) in the Dutch pasture ( veenweidegebied ) relies completely on artificial drainage of the peat soils. To prevent excessive subsidence, water authorities try to minimize the vadose zone. As a consequence, some pasture areas are too wet for access by tractors or cattle, and these will be lost for agricultural exploitation. This is a major problem for farmers in this area, and is already leading to farmers changing their activities. As stated above, annual greenhouse gas (GHG) emissions of the Netherlands (iii) are for 1-3% due to peat oxidation (Van den Bos, 2003), and directly related to the volume of the vadose zone. Since subsidence rates are an indicator of the vadose zone (a lower phreatic level implies more subsidence), they can be used as a proxy for the GHG emissions of the area. In terms of water management, (iv) the Netherlands has 24 autonomous regional water authorities ( waterschappen ) charged with managing water barriers, waterways, water levels, water quality and sewage treatment in their respective regions. They base their decisions to change ground water levels ( peilbesluiten ) also on subsidence predictions. However, in our preparatory research, we concluded that these predictions are never based on direct empirical data of subsidence, but only on modeling results using soil types (from drillings) as input. Consequently, these authorities are currently not able to assess the quality of these predictions, even though they have a major impact for agriculture, recreation, ecology, and civil society in general. Finally, the significance of subsidence for ecological long term planning (v) is large. Already now, the water authorities need to make decisions on socalled break-points ( knikpunten ). These are moments in time, when land use has to change from, e.g. pasture and cattle, to more wet ecologic situations, such as marshes and wetlands. Clearly, this has major impact on the typical Dutch landscape and biodiversity.
7 Page/of 7/17 Research methodology and technical feasibility The research methodology is based on first ideas tested in a preparatory study (Morishita and Hanssen, 2014), applied over a small area south of Delft, the Netherlands, see Figure 2A. We show the results of standard persistent scatter results in Figure 2B (an Envisat C-band time series), demonstrating that it is not possible to estimate deformation over the pasture with conventional methods. Only some coherent reflections stemming from farm buildings are visible. The research methodology of this project relies on (1) the spatial averaging of statistically homogeneous pixels using non-overlapping estimation windows, (2) a parametric deformation model and a generalized least-squares method, and (3) a combination of all available satellite SAR data stemming from different sensors see Figure 3(Left). In our preparatory study, we combine data from ALOS, TerraSAR-X, Radarsat-2, and Envisat and obtain subsidence rates for the test areas in the order of several centimeters per year, and a seasonal signal with an amplitude of almost 1 cm, cf. Figure 3. Figure 2 (A) Location of the test site, a pasture area south of Delft. (B) Typical Persistent Scatterer result over this area, showing only coherent points coinciding with buildings, and not at the pasture itself (Morishita and Hanssen, 2014) Yet, although these results are encouraging and suggest feasibility of the method, the numerical results still trigger fundamental questions. First, the estimated rates appear to be quite large if compared with model results. The preliminary version of the algorithm needs to be updated and improved, and quality assessment needs to be improved. Secondly, spatial resolutions of 230 meter were obtained disregarding the shape of the pasture fields. We expect that including such information in the processing approach will improve the results significantly. Figure 3 (Left) Overview of all SAR data as a function of time and orbital separation. The picture is intended to show how many SAR datasets have
8 Page/of 8/17 been used in the analysis. Lines connect acquisitions with coherent information. (Middle) Estimated subsidence rates in mm/y for the area of Figure 2. This is the main encouragement that observation of subsidence over pasture may be feasible, if the optimal data processing method is used. (Right) Amplitude of the seasonal motion in mm (Morishita and Hanssen, 2014). Regarding the physical processes, we will investigate the compaction and oxidation of organic shallow layers, focusing on the identification of driving mechanisms, the description of contemporary spatial and temporal variability, and the improvement of descriptive and predictive models. The observed geodetic subsidence signal is used to tune the experimental part of the physical study. The fieldwork based part of the study focuses on the construction and deployment of Surface Elevation Tables. The input from the geodetic observations will be used to identify optimal and representative locations of these devices. The results will be used to validate the geodetic data on a point-by-point level, enabling us to scale the methodology over wider regions, i.e., the entire western and northern part of the Netherlands. Cooperation other parties Apart from the main sponsors of the project, Hoogheemraadschap Delfland and Rijkswaterstaat, we seek close collaboration with other research groups at TU Delft (mainly in the soil sciences and water management), Utrecht University, Wageningen University and Deltares Research Institute. Links with (inter)national research programmes The project has a link with the Top Sector Agri and Food, since subsiding peat soils significantly impact the Dutch productivity in agriculture and food. It also relates to Top Sector Water: theme: Leefbare delta, and the prospective international coastal hazards supersite in relation to the Group on Earth Observations ( Expected results and potential users of the results of the project The project will yield, for the first time, geodetic estimates of subsidence due to shallow causes such as compaction, peat oxidation, and consolidation. These estimates will have a huge impact on water management strategies, since they enable water management boards, such as Hoogheemraadschap Delfland, to improve their long term predictions on the manageability of the subsidence problem and to assess the consequences of their groundwater policy on increased flood risk. They will impact agriculture, farmers and therefore the Dutch economy, as it may show that land which is currently appropriate (or thought to be appropriate) for agriculture may not be appropriate anymore within a few decades or less. (This is already a major concern for provinces in the western part of the Netherlands. They will impact the Dutch budget of CO2 and methane emissions, as the oxidation of organic material is a great contributor to these budgets. As of 2021, land use induced greenhouse gas emissions will become part of the European Union CO 2 reduction strategy. Counter-intuitively, they will help narrowing the estimates of subsidence due to mining activities, and therefore improve the attribution of damage, nowadays in the order of many millions of Euros per year, to specific parties. This is a consequence of the fact that disentangling the different origins of the subsidence is nowadays very difficult. The economic impact of the availability of reliable subsidence estimates will therefore be very significant. In fact, we address the manageability of
9 Page/of 9/17 a society largely living below natural water levels. In terms of SME interest, the possibility to measure deformation in green areas will widen the market opportunities for value-adding companies. Technically, the study will lead to new and improved ways to analyze very big data sets, based on advanced data processing algorithms. Finally, the results will be documented in peer-reviewed journal publications The likelihood that this study will lead to breakthroughs can be considered high, since (i) this type of information is nowadays simply unavailable, and (ii) we already have indications that shallow subsidence is locally greater than previously expected.

Personnel: full salary of one Ph.D. student (4 years) Nature of the own contribution and the contribution of other parties. The own contribution of the TU Delft represents the faculty overhead during those four years and the cost of the hours for supervising the PhD student, furthermore there is also the university overhead which is calculated as a P.M. post. The contribution from other parties (Delfland/RWS) represent the salary of the participants, corresponding to the hours invested in this project. Description of the research group The Department of Geoscience and Remote Sensing is embedded in the faculty of Civil Engineering and Geosciences. The department was formed early 2012, after a university reorganization that fused all groups working on geodesy, remote sensing and the earth and atmospheric sciences. More in particular, all radar research groups, originally from the disciplines of electrical engineering, aerospace engineering, and earth sciences, merged at that time in the department of Geoscience and Remote Sensing. This created a challenging, inspiring and innovative cluster of scientists and engineers with valuable and highly complementary skills and experiences. For example, both radar instrument development, (SAR and interferometric) algorithm design, computational optimization, geodesy and application development are now embedded in one single department. Relevant to this project, our department also holds specialists in geodetic data analysis and atmospheric and climate sciences. Hence, the project will benefit from the multi-disciplinary expertise of the department.

17 Page/of 17/17 Bijlage 2 Cases Delfland: 1. Meten effect van onderwaterdrainage op de maaivelddaling In het gebied van Delfland zijn recent een aantal kleine percelen voorzien van onderwaterdrainage. De verwachting is dat deze vorm van drainering minder maaivelddaling veroorzaakt dan in ongedraineerde percelen. Aandachtspunten: - Het gaat hier om graslanden van circa 50 x 50 meter Mogelijkheden onderzoek: - Door een vergelijking te maken van oude maaivelddalingsgegevens en maaivelddalingsgegevens van naburige percelen kan een betere onderbouwing worden gemaakt. - Betere resultaten kunnen behaald worden door resultaten worden te matchen met bodemeenheden (veen, klei, kreekruggen) en door bebouwing, infrastructuur, water uit te sluiten (filtering). 2. Monitoring maaivelddaling van lage delen Inzicht in de daling van lage plekken in landbouwpolders is nuttige informatie voor peilbesluiten en aanpak van wateroverlast. Aandachtspunten: - Het gaat hier om (kleine) grillige gebieden en vormen Mogelijkheden onderzoek: - Betere resultaten kunnen behaald worden door resultaten te matchen met bodemeenheden (veen, klei, kreekruggen) en door bebouwing, infrastructuur, water uit te sluiten (filtering). 3. Maaivelddaling per peilgebied Bij het opstellen van peilbesluiten wordt de maaivelddaling per peilgebied bepaald van de afgelopen periode (10 jaar). Hiermee wil Delfland afwegen of de drooglegging gelijk moet blijven door het waterpeil aan te passen aan die bodemdaling. Aandachtspunten: - De bodemdaling moet per peilgebied worden bepaald voor een lage periode (circa 10 jaar).
