摘要
The Edwards aquifer of south-central Texas, U. S. A. , a highly fractured and faulted group of limestone formations, is the major water supply for the San Antonio area. A discrete-state compartment (DSC) model or mixing-cell model, based upon the conservation of environmental tritium within the aquifer, was used to obtain estimates of groundwater mean ages, recharge, effective porosities and storage in the Edwards aquifer near San Antonio. The model confirmed previous analyses of flow in the Edwards system. Groundwater mean ages ranged from 16 to over 130 yr. The storage volume of the confined portion of the Edwards aquifer is 30. 9 km**3. The average annual recharge to the Edwards aquifer during the period 1953-1971 was 0. 614 km**3. Refs.
