Effect of Infiltration Modeling Approach on Operational Solutions for Furrow Irrigation

Infiltration in irrigated furrows depends on the variation of depth of flow and, thus, wetted perimeter along the field and in time. However, the magnitude of the wetted perimeter effect has not been clearly established due to soil variability, erosion and deposition, macropore flow, and other processes that affect the infiltration process. Hence, furrow irrigation models currently offer various alternatives, mostly empirical but some physical,...
