Recursos hídricos subterráneos en la cuenca baja del río Chambo.

Abstract

This study presents an analysis of the superficial and groundwater water flow, considering the supply and demand of this resource. This was done by using the database from SENAGUA (2019), based on the information of the concessions from the lower basin of the river known as the “Chambo river”. Field samples were also used in this study. The field samples were collected considering the framework of the following project "PIMI-15-02-Characterization of the aquifer system of the lower river basin of Chambo’s river using a hydrodynamic and geochemical approach: recharging processes and sustainable management of the resource". In order to do this, zoning of the location was used, which required us to divide the CBRCH into 9 different subzones by using different maps. Through analyzing the information provided by SENAGUA (2019), a map of the concession concentration. The resulting map shows that the highest concentrations of concessions are located in the main rivers, to this result we need to overlap the slope map and the appliance of soils map, in order to determine which zones would be the 9 zones that are mainly delimited by rivers. For each zone, the water availability were estimated, distinguishing the groundwater sources from the superficial water sources, both with the project's sample catalog and with SENAGUA’s database (2019) for 7 different kinds of usage. The sector that has more water usage in the CBRCH is agriculture, the irrigation process results in a total of 590 concessions granted. With the analysis of the geodiversity proposed by Carcavilla et al., (2007) it was possible to determine that the Chambo River and the East Side of the CBRCH present a high geodiversity due to the presence of geological formations from the Jurassic and Cretaceous times including geoforms of volcanic origin, fluvial and hillside.
