PHD THESIS
Background
The SafePass project aims to find the best
solutions for fish migration in regulated rivers,
from the perspectives of both the fish and the
hydropower industry.
The first task will be to track fish on their way
down and analyze their behavior under different
conditions. The observed behavior of the fish can
becombinedwith thedata fromthe3Dnumerical
model. This will help to detect possibilities and
find the most promising solutions for avoiding
fish entering the intake structure. Combining
this with the needs of water for hydropower
production we will aim to design an operational
solution that optimizes the fish passage and
hydropower production.
The second task will be the examination of
currently used and just developed prototypes
of trash racks for power plant intakes, and will
be tested in the hydraulic laboratory. The aim of
these investigations is to find a formation which
prevents fish from entering the intake and at
the same time has acceptable energy loss and
reasonable maintenance costs.
