Análisis de los procesos erosivos en las vertientes de la microcuenca Hato Viejo Municipio de Chitagá.

Abstract

The processes of soil degradation are dynamic, growing and of global concern that require the measurement, monitoring and control of these fundamental processes in the development of the region, in particular in the maintenance of environmental balance and economic and social sustainability. The objective of this work is the study, treatment, evaluation of the spatial dynamics of land use changes and erosion processes in the Hato Viejo micro-watershed, Municipality of Chitagá, through the analysis of the determining factors such as: the erosive potential of raindrops, topographic components, length and slope, soil texture, use / coverage and conservation practices. In addition, the susceptibility and erosion threat on the stream's slopes was evaluated from two detonating factors, such as precipitation and seismology; through the identification, geoprocessing, modeling and analysis of the processes, using a geographic information system (GIS) to generate the final graphic outputs where the temporal space variability of the erosion processes in the microbasin is represented, demonstrating at a general level that the loss of larger-scale net soil predominates on steep and steep slopes, which, influenced by a wide variability of rainfall, accelerate their dynamics.
