Abstract: Temporal and spatial changes in the flow profile decrease with time under furrow irrigation, and these slow changes suggest modifications in the simulation methods. Geometrically increasing time steps and node deletion at ...

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: 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 ...

Abstract: A climate-driven water resource model of California’s Sacramento River Basin (SACB) is presented, based on the Water Evaluation and Planning model Version 21 (WEAP21). The model’s configuration, calibration, testing, and ...
