For each grid cell, the Soil-Water-Balance (SWB) code used the hydrologic soil classification, land cover classification, available soil moisture capacity, surface flow direction, and daily climatic data of precipitation, minimum temperature, and maximum temperature. The SWB code calculated an estimation of recharge, in vertical inches of water, for each individual cell for each individual day and summarized the data as daily, monthly, or yearly outputs. Each cell took the inputs of precipitation, snowmelt, and surface water inflow then subtracted the outputs of interception, evapotranspiration, and surface water outflow. Any excess water from this summation was used to satisfy the available soil moisture, and when that quantity had been met, all remaining water was considered to be groundwater recharge.
