Investigation of the Optimum Connection of a Fish Pond with the Adjacent Main Riverine Flow

The optimum design of the opening through which a fish refuge pond communicates laterally to the main flow of a river was investigated. The study was based on the realization of physical and mathematical models. The physical modeling was realized via laboratory experiments which included the use of an open channel with a lateral reservoir. The flow characteristics measurements were realized with the PIV method. The mathematical simulations were based on the development of a 2DH hydrodynamic model and a quasi 3D sediment transport model. The study led to the optimum technical design of the system.
