This project included testing and development of traditional and new tools to characterize groundwater flow in fractured crystalline rock, including multi-well pumping tests, downhole flow measurement technologies, downhole fracture detection and borehole geophysical and cross-hole seismic data, and fracture distribution and geometry data. Constructed numerical model to simulate groundwater flow, including calibration to pumping tests. Developed analytical solution of transient crossflow between aquifers that can occur because wells connect different fracture zones.
Research was funded by the U.S. Department of Energy and U.S. Department of Environmental Protection, and the site was located in Raymond, California.
