Abstract

The Jasper (Miocene) aquifer is one of several important hydrologic units in the Gulf Coastal Plain. Because the Jasper aquifer underlies shallower aquifers in many areas, regional water withdrawals from the Jasper are not significant; however, it is capable of yielding 3,000 gallons per minute (200 liters per second) or more of water to wells in certain areas. The Jasper is underlain by the Catahoula confining system (restricted) and overlain by the Burkeville confining system. The Evangeline and Chicot aquifers, in turn, overlie the Burkeville and also are prolific water-yielding aquifers.

The ground-water hydrology of the Jasper aquifer in an area of about 20,000 square miles (52,000 square kilometers) was simulated by a two-dimensional digital model using a steady-state approach. The model represents hydrologic conditions prior to development by wells, when natural recharge equaled natural discharge. The model's grid pattern of 15 x 24 nodes varies from a dimension of 5 by 10 miles (8 by 16 kilometers) in the outcrop to 10 by 10 miles (16 by 16 kilometers) in the artesian section downdip from the outcrop.
