Modelación hidráulica del rio Ocoa para la identificación de zonas de inundación dentro del casco urbano del municipio de Villavicencio, desde el barrio Porfía hasta Kirpas

Abstract

This project was carried out due to several flood events that have presented the Ocoa River, which report material and human damage, especially in the section located between the towns of Porfía City and Kirpas because there are human settlements very close to the riverbed. del Rio. Through this study, we propose to model the flooding of the Ocoa River for a return period of 100 years and 50 years in order to identify the maximum flood area that this emergency covers, analyzing urban areas of threat to community. To obtain this result are defined as the main factors that generate a flood: precipitation, topography and runoff capacity of the basin. These parameters are close, at the beginning, to the content of the event, to the knowledge of the terrain, to the extreme event, to the information found in the Institute of Hydrology, Meteorology and Environmental Studies, The National Administration of Aeronautics and Space, the Colombian Geological Service. And for its application it is mainly used theoretical and practical knowledge on hydrology, hydraulics, geology, geographic information systems. The flood caused by the Ocoa River between the closed sections was obtained by the following variables: historical rainfall behavior, runoff level, the geomorphological characteristics of the basin, the hydraulics of the channel in the Porfía - Kirpas section. The results of this research can be used as a basis for decision-making in the creation of mitigation structures for flood risk in areas of urban affectation and expansion along the riverbed.
