Evolución geomorfológica fluvial reciente en rios tropicales andinos del ecuador: evolución geomorfológica y fluvial de la quebradra el qec (rio monjas), a partir del crecimiento de la mancha urbana.

Abstract

This work will be carried out in the Quebrada El QEC - Hydrographic Micro-basin of the Monjas River, Metropolitan District of Quito, where the urban acceleration of recent years has concerned threats of anthropic origin: floods, regressive erosion of ravines and landslides associated with its margins. This increase is associated with a loss of the hydrological cycle resulting from the waterproofing of the soil due to the construction of anthropic infrastructures. For this reason, when intense rains occur, the Monjas River presents peak flows, increasing its erosive power and therefore modifying the geomorphology of the river by destabilizing the margins of the ravine. The rapid morphological evolution of the Quebrada El QEC was documented through satellite images, a circumstance that was shown to monitor the mobility of the channel and landslides, as well as the impact of human activity on the modification of erosion rates.
