Modelamiento Hidrológico De La Quebrada San Idelfonso Mediante SIG En Trujillo, La Libertad 2020

– The research focuses on designing a Hydrological Modeling of the San Idelfonso Stream through a Geographic Information System in Trujillo. Where rainfall information was collected on the last fifty years of the occurrence of the phenomenon of the child and its incidence in the districts of Laredo, El Porvenir, Florencia de Mora, Trujillo and Víctor Larco Herrera. Also, the DEM was used with the Arc GIS software, Hec-RAS, Hec-HMS and Civil 3D software were used. The exact location of the San Idelfonso stream was obtained, the collection of thematic maps of different national entities. Also, figures and thematic maps that show rainfall during the last 50 years, being the years 1983, 1998, 2017, where a greater precipitation was observed. After analyzing the rainfall information, vulnerable areas were determined, obtaining an unmanned flight modeling, which shows the distribution of the San Idelfonso creek. Finally, a prevention alternative was proposed for a possible future coming and sliding; thus allowing to handle the situation with the least number of affected in the population. In this way, it was possible to design a hydrological model for the San Idelfonso stream taking GIS into account.
