It was considerado an intial setting with twenty-three cultures, and from the otimizagao with those cultures, determined himself two news cultures: a representative of the perennial, formed by on average of the characteristics of the perennial cultures with positive liquid prescription, and another one representative of the seasonal, formed with on average of the characteristics of the seasonal cultures with positive liquid prescription. Despite of sensible variations of the climatic situations, the results showed that water in all of the reservoirs exists studied, capable of supply the demands of form sustentavel.
