Abstract: The problem of irrigation canal regulation under demand delivery operation was formulated as an optimal control problem. To apply the linear optimal control theory, the Saint-Venant equations of open-channel flow were ...

Abstract: This paper presents a local optimal control technique (control of an individual gate) for operation of an irrigation canal with a single reach. By using the concepts of control theory, an expression for an upstream gate ...

Abstract: A well-designed level basin irrigation system is easy to manage and has significant potential for achieving high application efficiency and improved salinity control, particularly when the field is laser-leveled. Over the ...

Abstract: A friction correction factor (F

Abstract: Using a linearized finite‐difference model of open‐channel flow, the canal operation problem was formulated as an optimal‐control problem, and an algorithm for gate opening in the presence of arbitrary external disturbances ...

Abstract: Considering the minimum cost as the objective, the furrow irrigation system design problem is formulated as an optimization problem. A combination of monotonicity analysis, constraint activity, and condensation are used ...

Abstract: Knowledge of the sensitivity of performance and other related dependent furrow-irrigation parameters, in quantitative terms, to variations in field, design, and management variables can help save a considerable amount of ...

Abstract: The Saint-Venant equations of open-channel flow were linearized using the Taylor series and a finite-difference approximation of the original nonlinear, partial differential equations. Using the linear optimal control ...
