Investigating innovations in vertical slot fishway design

3.1 Vertical slot fishways Each type (a) vertical slot fishway, (b) pool and weir fishway and (c) step-pool nature-like fishway can have different subtypes according to their morphology and connections.Rajaratnam N, Katopodis C, Solanki S. 1992. New designs for vertical slot fishways. Can J Civil Eng 19: 402–414. vertical slot fishway - definition - English A vertical slot fishway and two Denil fishways (of 10 and 20% slope) built into a weir on the Lesser Slave River (55°18′N, 115°45′W) were studied from May 12 to June 25, 1984, to determine how effectively these designs pass north-temperate, nonsalmonid fishes.


Fishing Monthly Magazines : Impact of dams on fisheries Many fishways used in Australia are based on designs used for salmon and trout in the Northern Hemisphere. These fishways are ineffective for native fish species as they are too steep, too turbulent and cease to function during Qld's … Design of Fish Passages & Ladders with HEC-RAS Although vertical slot fishways can be designed to pass a wide variety of fish species over a significant flow range, they are less passable for fish that tend to follow or cling to walls or jump over weirs.

New designs for vertical slot fishways. Canadian Journal of Civil Engineering, 19(3), 402 – 414. doi: 10.1139/l92-049, [Web of Science ®] , [Google Scholar]) examined 18 designs of vertical slot fishways in order to develop effective but simple designs. They tested the sensitivity of the performance of vertical slot fishways to the length ...

Vertical-slot fishway is widely used in different shape of fish-way due to the adaptability to water level amplitude, the hydraulic characteristics of the vertical-slot fish-way of different scale has been extensively researched by researcher domestic and overseas, the energy dissipation mechanism and... Fish ladder - Wikipedia Written reports of rough fishways date to 17th-century France, where bundles of branches were used to create steps in steep channels to bypass obstructions. Alvaro Rodriguez | University of Umeå - Alvaro Rodriguez, University of Umeå, Departament of Physics Department, Post-Doc. Studies Image Processing, Education a Social Sciences. Services AFPS has completed construction for smaller fishways such as vertical slot, rock ramp and bypass fishways as well as culvert and pipe fishways.
