At present, I am conducting a field-based research on water flow and salt transport in the shallow saline aquifers and soils of the San Joaquin Valley (Southern Central Valley of California). Recent community-based projects include monitoring of the upper Fresno River watershed and the Upper San Joaquin River watershed involving water quality and discharge measurement, watershed delineation and snowpack calculations using GIS, and estimation of the climate change effects on the watersheds. Other basic and applied studies include measurement and modeling of unstable or finger flow in porous media (basic science), engineering improvement of irrigation systems in the San Joaquin Valley to raise water use efficiency, and irrigation scheduling.
