Estimation of the Water Balance in the Vinces River Watershed Office Automation and Geomatic Tools

Abstract

The Vinces River basin, located in Ecuador, faces significant challenges in its water management due to anthropogenic pressures and climate change. This study estimates the water balance of the basin using office automation (PETP and InnerSoft ISBH) and geomatics (QGIS) tools, to evaluate water dynamics, identify patterns of water deficit and surplus, and propose sustainable management strategies. Using the Thornthwaite method, an average potential evapotranspiration of 1,307.63 mm/year and an annual excess water balance of 1,322.97 mm/year were determined. In addition, the spatial analysis made it possible to map vulnerable areas and establish conservation priorities. The results show that the basin can generate approximately 6,240.37 Hm³/year, with an irrigation potential of 422,927.73 ha/year, which represents an opportunity to optimize water use in agricultural activities. The tools used proved essential for integrating climate and spatial data, providing a solid foundation for water planning and decision-making. This approach contributes to the sustainability of water resources, aligning with Sustainable Development Goal 6, promoting equitable and resilient water management in the region.
