Investigations of the effects of sediment deposits of the Jägerbach / Kamp Steinegg on the local flood protection
Abstract
The Jägerbach, located on the right bank of the Kamp river is one of the few tributaries that continuously delivers sediments to the river. Depending on the intensity and duration of the precipitation in the catchment area of the Jägerbach, this may result in more or less sediment transport into the Kamp. The deposits, however, lead to the formation of alluvial fans, which vary in their height and areal extent. On the left bank of the Jägerbach are houses which are endangered by loacal floodings. For this property, those deposits may reduce flood protection by reducing the active width. This could additionally raise the water levels at characteristic high flows (e.g., HQ30) by increasing vegetation on the deposit and thereby increased roughness in flood situations. The aim of the present project is to scientifically analyze and evaluate the effects of deposits of the Jägerbach on the flood discharge in the area of Steinegg and to derive a scientific management concept for sustainable water management in this section of the river.
