| Abstract: | Irrigation infiltration is the main source of ground water recharge in arid inland river irrigation area.Irrigation infiltration coefficient is an important index affecting the intensity of irrigation in farm field,its value is related to the assessment accuracy and utilization.In this the process of infiltration and redistribution of irrigation water,based on the principle of water balance,a method of calculating the irrigation infiltration coefficient is present,by using the soil moisture content of soil profile and depth of groundwater table at the same time.The case study shows that the method is workable and has practice value. |
