Green-Ampt MethodGreen and Ampt method is also used to calculate the infiltration and loss rate in runoff modeling. The Green Ampt Method is an acceptable loss model and is a simplified representation of the infiltration process in the field [20]. It is a function of the soil suction head, porosity, hydraulic conductivity and time.
