Methods & Models

The GWRP supports many types and levels of research from basic hydrologic research conducted by the National Research Program to development of new field techniques, geophysical methods applications, and computer model development. The Program is always trying to find more efficient methods of evaluating groundwater resources at a variety of different scales and these listed activities are examples of what is currently underway.

• Geophysical Methods and Applications
• Groundwater Model Development
• Estimating Groundwater Recharge in Humid Areas
• Darcian Method of Estimating Recharge
