Abstract: Assessment of the surface storage is of great importance in hydrological surface irrigation. For the Horton infiltration law used in the ALIVE model (Advanced LInear VElocity), an accurate measurement of surface storage ...

Abstract: Previously, surface irrigation hydraulic models used the principle of mass conservation to simulate the advance of water along the field and to solve the inverse problem of finding the infiltration function from measurements ...

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: A complete furrow irrigation model was developed based on the cumulative solution of the volume balance equation, rather than the incremental solution. Space intervals were given (constant or variable) to allow infiltration ...

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: A kinematic‐wave furrow model with spatial variability of infiltration is developed to solve directly for advance times. In addition, infiltration varies with wetted perimeter. During advance, the system of nonlinear ...

Abstract: Flow in surface irrigation is subcritical and downstream conditions can propagate upstream. The shooting or initial‐value method started from the downstream end and proceeded upstream against the flow. Saint Venant ...
