Water Level Maps In The Edwards (BFZ) Aquifer Jun Xia Environment and Water Resource Engineering Department of Civil Engineering University of Texas, Austin

Edwards (Balcones Fault Zone)

Edwards (Balcones Fault Zone) The Edwards aquifer covers approximately 4,350 square miles. It contains 11 counties. Water from the aquifer is primarily used for municipal, irrigation, and recreational purposes. San Antonio obtains its entire municipal water supply from the Edwards aquifer.

Data Collection well sites water-surface elevation in wells

Data Collection Problems: • characters every a few lines in the table which shows well sites • water-surface elevation in wells is not altitude from sea

Solving Problem 1

Well Sites in Texas totally 7098 wells in the state. two important areas

Well Sites in Edwards Aquifer

Solving Problem 2 get DEMs of the aquifer get elevation of each well site water elevation = well elevation - water surface elevation

Applications of The Map change of water level with time relationship between water level and precipitation use of groundwater resource
