Geophysical profiles (upper panel: RS2; lower panel: RS5) made with the vertical electrical sounding (VES) method (up to 200 m deep). Gravel and sands make up the hydro-stratigraphic units with the greatest potential to store and transmit water, forming the main aquifers.

A hydro-geochemical characterization was conducted in the northern part of the Sonora River basin, covering an area of 9400 km2. Equipotential lines indicated that groundwater circulation coincided with the surface water flow direction. Based on the groundwater temperature measured (on average ∼21 °C), only one spring exhibited thermalism (51 °C)....
