Manual de análisis de amenaza por fenómenos de remoción en masa bajo agentes climatológicos en el área urbana y periurbana de Villavicencio a escala 1:2000

Abstract

Villavicencio's city is located in the Colombian Orinoquía, to the northeast of the Meta's departament in the piedmont of the Eastern Cordillera, with important presence of precipitations and topography that refers high susceptibility to landslides. This produces great disasters due to the mass movements occurring in areas of high population density or pass of vital public services. For this reason, it is necessary to have pertinent studies to analyze the threat presented by hillside areas in the municipality of Villavicencio. The manual of analysis of threat by mass movement under climatological agents aims to be a practical guide, which allows to zonify the threat by this type of phenomena, at low cost, in the hillsides located in the urban and periurban area of Villavicencio. Likewise, it is an indirect contribution to the basis of an improvement of the Territorial Planning Plan. The reason for making the manual under climatological agents is due to the high rainfall that has occurred in the municipality as consequence of climate change. The present project is characterized as a qualitative and exploratory approach, because at present there is no manual to identify these procedures in a thorough way, exclusively under the precipitation detonator. To achieve this objective the "Methodological guide for studies of threat, vulnerability and risk by mass movements" of the Colombian Geological Survey, was consulted, together with a study in the sub-normal settlement La Nohora, which allowed us to know firsthand the activities necessary to carry out the analysis of these phenomena in a specific area of the municipality. The development of the manual allowed identifying that it is possible to perform a zoning of threat in a simpler way in comparison with the requirements demanded by the governmental entities in charge of generating these studies.
