The comparison of advance and erosion of meandering furrow irrigation with standard furrow irrigation under varying furrow inflow rates
Abstract Meandering furrow irrigation (Gholam-gardeshi irrigation) is a modified form of furrow irrigation, which has being used in Iran, but to date, there is no study about the erosion of this method of irrigation. To measure the erosion of meandering furrow irrigation and to compare the results with standard furrow irrigation, two experimental fields with different soil textures and furrow inflow rates were used. The experiment utilized a randomized factorial design with three replications for each treatment. In both methods, the developed second order polynomial equation for the erosion, and advance equation were able to predict the field data with coefficients of determination of more than 0.94. The results showed that the velocity of advance, tail water runoff and erosion are significantly lower for meandering furrow irrigation as compared to standard furrow irrigation. As the furrow inflow rates increased, erosion and runoff in both irrigation methods increased significantly.
