| Abstract: | In cities located in low-lying areas on soils susceptible to subsidence, water managers constantly have to balance between pumping away enough water to prevent flooding and pumping away too much water, which accelerates subsidence. This balance is expected to become even harder to find in the future, as climate change increases the intensity of both rainfall and drought. Adding surface water to cities is a measure that can help in reducing pluvial flooding and groundwater fluctuations. This study quantifies these reductions by studying the restoration of the Binnensingel canal in the Dutch city of Vlaardingen with the use of the integral hydrodynamic model 3Di. The model is calibrated and the effects of a future rainfall events on the current study area are quantified in terms of depth and duration of pluvial flooding, the amount of vulnerable buildings, magnitude of groundwater fluctuations and water balance terms. Then, the canal is added to the model with different variations in length, water level and connected area and the same rainfall event is put on the adjusted model. The addition of the canal reduces the extent of pluvial flooding and groundwater fluctuations only slightly, but become larger for canal versions with a higher connected area or lower water level. |
