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: 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: The article proposes a mathematical model of an automatic upstream water level control gate designed to operate under free and submerged flow conditions, called the Vlugter gate. This automatic gate controls the upstream ...

Abstract: A canal automation algorithm named CLIS has been further developed and evaluated using test cases set by the ASCE Task Committee on Canal Automation Algorithms. The control algorithm is based on an inverse solution method ...

Abstract: This article describes the hydraulic behavior of a mixed water level control hydromechanical gate present in several irrigation canals. The automatic gate is termed “mixed” because it can hold either the upstream water ...
