Numerical Calculation of Infiltration in Furrow Irrigation Simulation Models

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 of flow (and wetted‐perimeter) conditions. Four computational methods were compared for the former condition and only one was tested for the latter. The merit of the procedures was evaluated in relation to the performance of a...
