| Abstract: | Hydrosedimentological models are used for the acquisition of relevant information for planning and
management of water resources. The elaboration of scenarios, either realistic or hypothetical, without high
cost and making possible the study of the different hydrological processes results are a great advantage of
computational models. The hydrosedimentological model SWAT (Soil and Water Assessment Tool) was used
in the simulation of the “Riacho dos Namorados” watershed allowing the investigation of four different
scenarios. The scenarios have glimpsed all the area considering the entire basin area subject to different
usages, namely, the native vegetation “Caatinga”, reforestation with “algaroba” (mesquite), cultivation of corn
and bare soil. The results have been compared in terms of runoff generation and soil erosion among each other
and with the actual situation in the basin of diverse soil uses and the presence of four storage dams. The
simulation with the model SWAT provided consistent results in runoff and soil erosion, ensuring its
effectiveness and highlighting the importance of the study of scenarios in decision making. |
