Hydrology and Climate Change Impacts from Field Scale to River Basin Scales in the Pacific Northwest
(Seminar/Conference)

Assistant Professor

Abstract
Ensuring adequate supply and quality of water is critical to meet increasing human and ecosystem needs impacted by climate variability and change in the 21st century. The availability, quality, and timing of water is also severely threatened due to a general intensification of the hydrologic cycle (precipitation, evaporation, streamflow, recharge) caused by climate and land cover/land use changes, as well as increasing water demand around the globe. Climate change will make water resources planning management based on historic climate conditions less reliable in the future. A few selected river basins in Idaho that encompass a contrasting environment for the hydrologic assessment viz. managed/natural, surface/ground water interaction, agricultural/forested ecosystem will be presented. Interaction between the land surface-atmospheric processes and vegetation is evaluated in both natural ecosystems and irrigated agricultural lands in the Pacific Northwest. Results will be presented from the feedback analysis and the complementary relationship between the actual evapotranspiration (ET) and the potential evapotranspiration which can provide an ideal framework for estimating ET in the future.
Biography
Dr. Sridhar's research emphases are: climate change impacts, hydrology, and water resources. Dr. Sridhar joined the Department of Biological Systems Engineering at Virginia Tech in January 2014. Previously he was an associate professor in Civil Engineering at Boise State University. Prior to joining Boise State he was a research faculty at University of Nebraska-Lincoln and University of Washington. Dr. Sridhar earned his Ph.D. in Biosystems Engineering (Hydrology) at Oklahoma State University in 2001. He conducts modeling research to understand the impact of climate change on hydrology and water resources as well as land-atmosphere exchanges. He is a Registered Professional Engineer in Idaho and Nebraska and a member of ASCE, AMS, AWRA, AGU, and AAAS.
