Abstract: This paper analyzes the convergence of a numerical model for the quantification of lumped furrow infiltration parameters. The model minimizes the squared difference of observed and model‐predicted advance times as a function ...

Abstract: A complete hydrodynamic furrow irrigation model was developed that solves for time of advance as a function of distance. Solution of the system of finite‐difference equations is obtained with a shooting algorithm. After ...

Abstract: The computation of wetted‐perimeter‐dependent intake in a furrow irrigation simulation model using an empirical infiltration formula was examined. Different formulations were applied under increasing and decreasing depth ...

Abstract: The reliability of furrow‐infiltration parameters computed from advance measurements was analyzed. Lumped parameters were obtained using the least‐squares approach. The objective function was formulated using advance time ...

Abstract: The optimal management of a cutback‐furrow‐irrigation system with spatially variable infiltration based on an average intake function was analyzed. The problem was formulated as a cost‐minimization function subject to ...

Abstract: This paper examines the problem of routing known water demands through gate-controlled, open-channel irrigation delivery systems. Volume-compensation principles were used to route multiple demands in multiple-pool canal ...

Abstract: Automated open- and closed-loop control systems can enhance the performance of irrigation delivery systems. This paper examines the response of the canal test cases developed by the ASCE task committee on canal automation ...

Abstract: Irrigation practitioners use empirical infiltration equations. Theoretical infiltration equations are currently not capable of capturing surface irrigation infiltration behavior, particularly during initial wetting. For a ...
