Abstract

In the framework of territorial transformations in the Choapa river valley, we analyze the dynamics of geomorphic processes on basin scale. Special attention is given to changes due to human activities. In semiarid environments, both natural and anthropic landscapes have an immediate dynamic response to varying intensity and impact of rainfall events such as the phenomenon of El Niño. Intensive farming on hillsides, cones and glacis, is an emerging industry, inducing transformations of topography, vegetation and soil. We analyze the current geomorphology characterized by inherited forms, features and their process dynamics. Geomorphological and topographical models are applied to assess the relevant morphodynamics. The models yield information on the natural hazard of mass movements and fl uvially triggred erosion processes for the two study areas Salamanca and Panguesillo.
