Front of Mind - Swales, infiltration, high groundwater
Floris joins us to tell us about research that he has completed recently looking at how quickly the stormwater in wadis (AKA swales) takes to disappear after a storm event. Floris has dosed numerous swales in The Netherlands and even completed repeat dosings to investigate the effects of concurrent storm events. You can see footage of Floris's swale research in the episode or directly in the videos below. For a country that is largely below sea level and facing increased rainfall intensity due to climate change, this is an interesting application of water sensitive urban design to manage flooding.
