Description

Abstract:

The baffle-brush-fishway combines the properties of a superactive baffle (Larinier) fishpass with the features of the brush-furnished fishway. Both types mark the extremes of the hydraulic spectrum in fishpasses. The baffle fishway exposes a high turbulence flow with a mean velocity around 1,1 m/s while the brush-type fishway provides a multiple-structured migration corridor with low velocities. A transition zone provides a continuous crossover of flow properties. Thus, any fish can choose a migration corridor which meats it's demands and abilities. The presentation explains the main features of this type and adresses basic hydraulic calculations such as rating curve, friction factor and design procedure.
