Modelación digital geomorfológico fluvial del río Bachillero ubicado en la provincia Guayas mediante el uso de sensores remotos y sistemas de información geográfica.

Abstract

This work presents a fluvial geomorphological digital model of the Bachillero River, Guayas, using remote sensors and geographic information systems to perform an evaluation that compares the same results that can be obtained by performing the work of the field, compared to the digital model. For this comparison, specifically seeks to reduce the use of economic resources, work and time. It is known that, over time, most rivers have had hydrological and geomorphological alterations, mainly due to the influence of man and his activities, in which modifications have occurred such as river channels, floodplain variations in landscapes that affect the water supply. The results of these alterations become negative, the loss of physical habitat, the interruption of the continuity of the river and the lateral separation between aquatic, wet and terrestrial ecosystems, have damaged the ecology of the rivers. From the characterizations of the geomorphological changes of the river, you can investigate layer by layer and evaluate the history of the river, and therefore determine the specific human intervention that has participated in these alterations of the river. The characteristics of hydrological vegetation, geomorphological vegetation and riverside areas, used by spatial scales and the use of different data sources, are essential. To support potential underlying problems, a temporary geomorphological analysis of rivers should be done to create effective solutions to address possible future scenarios.
