Morphometric analysis of micro-watersheds in Achupallas Parish, Sangay National Park, Ecuador using GIS techniques

Abstract:

Introduction The structure model of the earth is strongly influenced by watershed as the preferred directions of surface flows define the erosion mechanisms and sedimentation (4). These processes are the result of the interaction of land use, climate, geology, soil type, topography and vegetation cover (4). In Geology, relief and climate are the primary determinants of running water ecosystems functioning at the watershed scale (1, 2). Different workers define watershed differently. Watershed is a natural hydrological entity which allows surface run-off to a defined channel, drain, stream or river at a particular point (3). Also it represents run-off and infiltration areas where rainfall tends to be drained into rivers, lakes or into sea.
