The downstream ecological consequences of two controlled “free flow” flushing operations
designed to remove sediments accumulated in an alpine reservoir are described. The main …

Sediment trap** within reservoirs is a worldwide phenomenon which impairs the
ecological functioning of upstream and downstream ecosystems. It also reduces reservoir …

Dam sediment flushing can reduce reservoir sedimentation and deliver sediments to the
downstream rivers. However, deceased fishes are often found in the Yellow River during the …

Run-of-river hydropower plants (RoR HPPs) are capable of interrupting the sediment
connectivity of many alpine rivers. Still, there is a lack of systematical investigations of …

Sediment concentration usually increases during the reservoir sediment flushing or natural
floods, which may result in acute hypoxia stress and death of fishes in river reaches …

This thesis focuses on the study of the negative effects induced on stream ecosystems by
hydropower schemes in an Alpine river system. The downstream ecological consequences …

Sediment flushing is one of the proposed methods for preserving the storage capacity of
dam reservoirs. In free-flow flushing (ie, flushing with complete drawdown), the incoming …
