Knowledge of hydrological variables is essential for the proper management of water resources. Hydrological models are able to represent the behavior of a watershed in a complex way, allowing detailed analysis from their results. The physiographic description of the basin is one of the basic premises for the use of these models. Aiming to present information not shown in the literature, the present work aims to conduct a morphometric and hydrological study of the Real river basin, located in the states of Sergipe and Bahia, with the integration of the Geographic Information System (GIS) and the rain-flow model SMAP. Automatic delimitation with GIS presented satisfactory accuracy with low error, allowing the calculation of concentration time by the methods of Kirpich, US Corps of Engineers and Dooge. The rain-flow model performed well in the validation, with results consistent with the basin. Statistical tests revealed non-stationary behavior for extended flow series, with a decreasing trend from the 70's. When calculating water availability with the extended series, there was a reduction of the minimum flow in the basin, especially in the humid months.
