摘要：Fish behaviour investigations under controlled laboratory
conditions but nature like environment were conducted to clarify the
efficiency of inclined and horizontal screen planes for fish protection and
fish downstream passage at hydropower plants concerning different
potamodromous species and various sizes. The dependency on the
underlying geometric and hydraulic parameters was investigated and
comprehensive models were deduced to describe these relations. Adequate
geometric and hydraulic design could achieve high levels of fish protection
and downstream passage efficiency, even for small fish, weak swimmers
and riverbed/bottom oriented species. The results imply good
transferability and accordance with field observations at large scale
facilities and can provide valuable information for facility design.
