Sven HARTMANN: SEDIMENT MANAGEMENT OF ALPINE RESERVOIRS CONSIDERING ECOLOGICAL AND ECONOMICAL ASPECTS
Abstract: Alpine Regions are regarded as a valuable
source of clean drinking water and of great importance for hydro power
use. Management of water as an extremely valuable resource is guaranteed
by numerous reservoirs enabling a third essential task: flood
protection. Sediments are transported in rivers originated from natural
geomorphological processes in alpine regions accumulating material in
reservoirs. Thus storage capacity is reduced interfering with the needs
of water supply, flood protection and hydro power. However, the lack of
transported material in downstream sections heavily affects ecological
variety, river bed stability and groundwater. A wise management of
sediments on basis of experiences gained on national level is needed to
establish trans-national actions to preserve existing reservoirs and to
avoid uncontrolled exploitation by constructing new storage capacity.
