Abstract: The flow characteristics upstream and downstream of sluice gates are studied experimentally and numerically using Reynolds averaged Navier-Stokes two-dimensional simulations with a volume of fluid method. Special attention ...

Abstract: To avoid sediment deposits in the downstream portion of irrigation channels, the outlets must extract a concentration equal to or higher than the one in the channel. In Pakistan, although channels have been designed in ...

Abstract: To promote water control in coastal areas developed for agriculture, tidal hydraulic structures (doors and flap gates) are used for the hydraulic management of irrigation and drainage networks. By closing when the water ...

Abstract: Planning maintenance activities in surface irrigation systems is essential for optimal use of the annual credits. In many countries, the equity of the water distribution is largely affected by sediment deposition but budgets ...

Abstract: The contraction coefficient under sluice gates on flat beds is studied for both free flow and submerged conditions based on the principle of momentum conservation, relying on an analytical determination of the pressure ...

Abstract: Currently, discharges passing measurement devices and structures in unsteady flow conditions are determined based on relationships developed for steady flow condition due to lack of sufficient data. In this study, the ...

Abstract: This paper proposes an efficient mathematical model of an automatic upstream water-level control gate, called a Begemann or flap gate. This automatic gate controls the upstream level close to a reference level for free ...

Abstract: This study addresses the sensitivity of short-term flow forecasting in the Seine River basin (
