Einfluss von Versiegelungen mit anschliessender Versickerung des Niederschlagswassers auf den Wasserhaushalt von Hängen

Changes to hillslope hydrology due to surface sealing in urban areas in combination with decentralised infiltration measures for precipitation are considered. Physically-based models of the water balance of selected hillslopes were applied. Present agricultural use is compared with the planned urbanisation and decentralised infiltration measures. The main impacts are on a local scale due to the transfer from the sealed areas towards the infiltration areas. Overall effects are small.
