Abstract:

The current water policy aims to accelerate discharge, which is causing problems predominantly in urban areas and densely populated lowland areas. To address and prevent these problems, the water policy should concentrate more on water retention. In this context, the research focusses on the local and regional effects of increasing water levels and delaying discharge in regional water systems. Backwater effects resulting from sharp bends and the obstruction by wood in streams remain poorly understood to date, and are considered key sources of uncertainty in predicting the effects of stream restoration and water retention measures. Regionally, streams are typically analysed in isolation from the river system with the risk of simultaneous occurrence of discharge peaks in the river and its tributaries. Within a sub-catchment, groundwater variation near rivers is rarely being analysed as a response to surface water dynamics.
