The hydrological Model used in this research was Vflo, this model use finite elements that can simulate streamflow based on geospatial data to simulate interior locations in the drainage network and determine channel flow and overland flow, it was fundamental a physical configuration of the watershed to be studied, such as a Digital Elevation Model (DEM), the topography digitalized, soils map, Land use map and information about the basin. Some hydrologic and hydraulic studies have been conducted by Sepulveda et al., [1996]; Rojas [2012]. Table 33. Drainage area peak discharge relationship [FEMA, 2012].
