Current Research

Effects of climate change and land management on water quantity and quality; Application of computer simulation models, GIS, and remote sensing in quantifying water balances at multiple temporal and spatial scales. Impacts of global change on water supply and demand. Forestry Best Management Practices in affecting and soil erosion and sedimenttransport in watersheds. Hydrology of forested wetland ecosystems under environmenal change; Impact of wildland fire on watershed hydrology.
