The chosen area includes a section of National Route 150 up to the International Border Pass to Chile, access to the future international tunnel of Agua Negra, between Argentina and Chile in a sector of the Western and Central Pre-Andean. One of the most important tools in hydrological analysis is the morphometric survey of a river basin, which allows establishing evaluation parameters on the behavior of the hydrological system of the river basin areas. Geographical information system (GIS) has emerged as an efficient tool in delineation of drainage pattern and ground water potential and its planning. A total of 122 river basins were identified and delineated, but only 3 (those of larger surface area) were selected for morphometric analysis and as a suitable case to evaluate the potential magnitude of flash floods in relation to their associated hazard level in the region. In addition, a peak discharge analysis was performed to predict approximately the behavior of the river basin in the presence of a series of theoretical rainstorms that may generate unusual runoff volumes that make up such flash floods. This study, when properly combined with geomorphology and geology analyses, helps to elaborate a primary hydrological diagnosis to predict the approximate behavior of the river basin at the time of heavy rainstorms.
