Statistical Analysis of Water-Level, Springflow and Streamflow Data for the Edwards Aquifer in South-Central Texas
|Description||Development of data-based simple and multiple linear regression equations for estimating water levels, springflow and streamflow in the San Antonio region of the Edwards Aquifer|
|Report Number||USGS 76-393|
|Publisher||US Geological Survey|
|Location||Edwards Aquifer, Balcones Fault Zone, San Antonio Segment|
Water-level, springflow, and streamflow data were used to develop simple and multiple linear-regression equations for use in estimating water levels in wells and the flow of three major springs in the Edwards aquifer in the eastern San Antonio area. The equations provide daily, monthly, and annual estimates that compare very favorably with observed data.
Analyses of geologic and hydrologic data indicate that the water discharged by the major springs is supplied primarily by regional underflow from the west and southwest and by local recharge in the infiltration area in northern Bexar, Comal, and Hays Counties.
