The water availability of a river basin depends on the temporal and spatial variability expressed by several hydrological functions, which are influenced by climate, physiography and soil use. This paper proposes to spatially evaluate the water distribution in the Apeú river basin, through the simulation of water production (WYLD) generated by the SWAT model, during the period from 2007 to August 2018. For this purpose, the SWAT model for the simulation of diverse information that compose the water balance, especially the water production, from information of use and type of soil, slope and climatic data obtained from organ such as IBGE, INPE and INMET, as well as calculated morphometric characteristics from the Geographic Information System. The results showed that WYLD is closely linked to the dynamics of soil uses and occupations and morphometry of the Apeú river basin over the years analyzed, not only the seasonality of rainfall in the region. Still, these results showed that as a result of these changes suffered by the basin caused an increase in about 30% of the water losses and reduced their production by up to 60%, which may be detrimental to the population that depend on the basin.
