NTGS February Meeting 11:30 AM Thursday Feb. 15 at the Wichita Falls Country Club PLEASE REMEMBER to RSVP

Understanding the nature of stream-aquifer interaction is important for understanding the degree of hydraulic connection between streams and adjacent aquifers within any given watershed. Such information is necessary before the effects of groundwater pumping on streamflow, or the effects of surface-water runoff on aquifer recharge, can be assessed. Traditional techniques to analyze stream-aquifer interaction are based on digital groundwater flow models; however, aquifer parameters for model calibrations are generally unavailable or difficult and costly to obtain. Recession curve analysis is an alternative approach to determining stream-aquifer interaction. read more
