Influence of land use and occupation on the silting of Bom Jardim Reservoir, Uberlândia - MG

Abstract

The silting of reservoir often reduces its life. Simulations about production of tributary sediments to the Bom Jardim public supply reservoir, in Uberlândia (MG), were performed through the SWAT software (Soil and Water Asscessment Tool), in order to evaluate the interference of the land use in the reservoir sediment supply. In the simulations, the type of land use was applied, and the percentage of Agriculture replaced by Forest was varied. It was verified that the higher the percentage of Agriculture replaced by Forest, the lower the sediment production. A program was used to calculate sedimentation of reservoirs and the conclusion is that the greater the reforestation in Agriculture areas, the lower the sedimentation in the reservoir.
