The total field area al an agricultural irrigation site in a semiarid region is 4800 acres. The proposed total surface area of the storage reservoirs is 300 acres. By water-balance calculations, determine the storage requirement based on the data listed below. The total water available each month is calculated in acre-inches by summing the effluent available plus precipitation minus evaporation loss from the storage reservoirs. The monthly irrigation requirements listed in the table were determined by estimating the consumptive use by the crops most likely to be grown at the site, taking into account optimum economic farming operation, crop rotation, and planting and harvesting times. Assume that the storage reservoirs are empty on October 1.
