Flooding – Water depth in extreme precipitation urban (2018)
Description
This map shows the result of a stress test for the urban area of Zuid-Holland. The map provides insight into where flooding is likely to occur after an extreme shower of 100 millimetres in 2 hours.
The stress test of the urban area was carried out with 2D terrain models (3Di) built from the filtered and interpolated General Height Map Netherlands (AHN2 and AHN3), information on land use (for friction) and about soil (for infiltration).
The resolution of the results is 0.25 m². For the urban area, integral models have been used for various municipalities in which the sewage system is also included (put on the low model information for this purpose and click on the map for additional information).
For buildings (source: Bag) a floor level of 15 cm above ground level has been adopted in the terrain model. The underflow of buildings via thresholds has not been taken into account, as detailed information of threshold height is still lacking.
