Flooding – current soil disposal (2020)
Description
This map shows the available storage in the soil (mm) in current climate and at an average high groundwater level (GHG).
Precipitation intensity is expected to increase further until 2050. This applies to both summers and winters. In areas with high water levels and groundwater levels and a low infiltration capacity (mm/hour), a rain shower generally causes first flooding in these areas. In areas with lower water levels and groundwater levels and a high infiltration capacity, water nuisance will generally be less likely due to the rapid infiltration of water into the soil and the availability of more soil storage.
Soil storage on the map can be used even better in times of (extreme) rainfall, so that flooding can be avoided elsewhere. This map provides an initial insight into the spatial distribution of the available soil storage, based on the calculated highest groundwater level with the National Water Model (NWM) in the current climate. The highest groundwater level is usually reached in the winter months. (See also the map GHG currently in the Climate Atlas). Because the average groundwater level is calculated, it is the ‘worst-case’ available soil storage, where the groundwater levels are high.
This map aims to get a first picture of vulnerable and promising areas for soil storage, as input for integrated climate sessions. In order to quantify the severity and extent of the bottlenecks and to develop opportunities, further detail is needed. This is particularly true for urban areas.
