Abstract: This Technical Note presents the results of a large set of laboratory tests and tries to determine the conditions that ensure the existence of a water cushion that is not expelled by the impingement of a nappe (effective ...

Abstract: The performance of two particular designs of vertical slot fishways for two different slopes was studied in a wide range of discharges. Water depths were measured in almost the whole surface of pools. A linear relation ...

Abstract: A nonintrusive method to calculate water depth and discharge in partially full pipes using data from a single ultrasonic Doppler velocimeter (UDV) profiler is presented. The position of the free surface is identified from ...

Abstract: Vertical slot fishways are hydraulic structures which allow the upstream migration of fish through obstructions in rivers. The velocity, water depth, and turbulence fields are of great importance in order to allow the fish ...

Abstract: The collection of field data is essential to monitoring in river basins to prevent flooding in areas with intense rainfall. A network of stations equipped with ultrasonic sensors was installed in a wet basin in Northwest ...
