Monitoring and analysis of groundwater flow in Venado Tuerto using a network of boreholes and geospatial tools.

Abstract

The Environmental Laboratory of UTN-FRVT has established a network of piezometers in urban and rural areas to monitor groundwater levels and provide valuable information about local water resources and their management, which is essential for addressing challenges related to these waters in a constantly changing world. Topographic data, groundwater levels, and reference points were used for this study. Using them, hydraulic equipotential maps and groundwater flow lines were created using GIS software and geospatial modeling tools. It is observed that groundwater flows in a northwest-south direction. A recharge area is identified in the northwest, divergent flow lines, and a discharge area near 'Estancia La Victoria' lagoon, where the flow lines converge. Furthermore, a depression cone is evident in areas with localized pumping, representing a forced discharge zone.
