Análisis de amenaza por procesos de remoción en masa bajo agentes climatológicos en el municipio de Villavicencio, Meta, zona de estudio La Nohora.

Abstract

Villavicencio is located in the region of the Colombian Orinoquía, the northeast of the Department of Meta in the foothills of the Cordillera Oriental, with an important presence of precipitation and high susceptibility to landslides. The Nohora is a subnormal settlement that has caused loss of vegetation cover on the hillside and increased sliding probabilities. This study gives us the possibility of determining the probability of landslide produced by precipitation in a given time based on the analysis of the components of the soil in the study area and the extreme events that may trigger a removal phenomenon. The objective of this research is to identify the probability of a mass removal event under extreme rainfall weather agents by simulating the characteristics presented in the area in order to evaluate the threat level of the area of Study, making a diagnosis of the current condition of the hillside, distribution of land use and the level of threat throughout the entire subnormal settlement as such. According to the results of this research is evidence that 92.2% of the area is at a level of threat between medium and high, which generates some concern when revising possible alternatives to mitigation and normalization of the legal condition of the Area.
