Fish facilities at the Belleville weir on the Loire River, the Bergerac dam on the Dordogne River, and the Golfech powerhouse on the Garonne River were optimized by the use of hydraulic model studies at the "Institut de Mecanique des Fluides" at Toulouse. In the first two fishways, flow conditions, i.e. flow velocity, drop between pools and rate of energy dissipation per unit of volume, were studied in relation to tailwater and headwater fluctuations. The main purpose of these studies was to optimize the position of entrances and determine the discharge needed to provide adequate attraction at these sites. The modeling resulted in design changes that should improve fish passage.
