Issue

Rainwater flooding

Flooding due to heavy rainfall or high surface water levels.

Heavy rainfall can cause floodings in cities. This is also the case in Rotterdam, in particular the city centre. During heavy rainfall the sewer overflows are discharged on the canals increasing the water level.

Solution

Urban floodplain

Urban floodplains are lowered areas along a river or other surface water in urban area, that provides space to rising water levels. This causes less flooding.

Pros

  • Multifunctional use of the area.
  • Increased water storage.
