Development of a new method for determination of infiltration coefficients in furrow irrigation with natural non-uniformity of slope

In this study, a new method was developed to calculate the infiltration coefficients in furrow irrigation with natural non-uniformity of longitudinal slope. For this purpose, 12 usual tilled furrows with 42 m length and 60 cm width were selected. Then, five irrigation events were carried out and the advance-recession and inflow-outflow data were collected. The parameters of the infiltration equation in power-polynomial form (Kostiakov–Lewis)...
