Flood risks
Flood risks come from the Dender River; the risk probability is considered medium
- The Dender has naturally a quick hydrological response because the combination of a strong topography and the loam soils in the uphill zones (Vlaams Milieumaatschappij, 2016). In case of intense rainfall, the river response is relatively quickly, increasing its level. Furthermore, the Dender Basin has been subject to land sealing through urbanization enhancing this process.
- The last flood of 2010 had a lot of impact and was identified as having a return period of 100 years. During these floods, an estimated 51 households were flooded (CIW, 2011). According to forecasts this could change into a 20 years return period by 2100 onwards. The total financial damage after the floods of 2010 was estimated at 180.000.000 EUR for the whole Dender catchment (Tempels, 2016).
- Impacts: If a flooding occurs, the potential number of households affected would be 228 (Tempels, 2016).
