The Deep Percolation Model estimates on a daily-basis the long-term average ground-water recharge from precipitation. It has been developed to simulate the recharge in large areas with variable weather, soils, and land uses. The model incorporates areal distribution of precipitation, potential evapotranspiration, snow accumulation, evaporation and melt, interception by plant foliage and evaporation of intercepted moisture, surface runoff, soil moisture accumulation and evaporation, transference of unused energy, and plant transpiration. The minimum data sets required are daily values of precipitation and maximum and minimum air temperature, soil thickness, and available water capacity, soil texture, and land-use.
