Study links groundwater with surface water in Devils River
A Southwest Research Institute (SwRI) study provides detailed models linking groundwater in a Texas aquifer to the surface flows in one of the state's most pristine rivers. The study shows how karstic pathways of the Edwards-Trinity Aquifer follow the same channels as the Devils River watershed, creating natural springs that sustain the river. "Natural springs play the major role in sustaining flows in rivers located in a semi-arid climate that experiences extended dry periods," said Ron Green, the SwRI scientist…
