Hydraulic and Biological Aspects of Fish Passes for Atlantic Salmon
Abstract: This paper describes a series of novel experiments testing the relative efficiencies in passing juvenile salmon �parr � through a range of model fish passes incorporating devices such as vertical slots, orifices, weirs, and combinations of all three. The hydraulic parameters—head loss, vel...
