he model’s minimum dataset for a single year can be used to simulate water balance and other model outputs for that year. But in order to forecast future crop yield and water balances, DSSAT needs at least 10 years of basic climate data. Estimated water loss from crop and tree use in study areas can be calculated from model output data and existing secondary data in the area. Results can be used to support water management and planting decisions, and help avoid drought periods and water conflict situations. Water Balance can be used to evaluate impact of water loss from intensive agriculture on watershed functions
