GEOG Seminar 4/11: Karen Prestegaard, "On the Temporal and Spatial Scaling of Hydrological Processes"

Thursday's GEOG seminar will feature Asssociate Professor Karen Prestegaard from UMD's Department of Geology at 3:45 to 5:00 p.m. (EST) on April 11.

Abstract:
Climate and land use changes can affect hydrological processes, water balances, and hydrological extremes such as floods and droughts. To quantify change, the underlying characteristics of a hydrological system need to be characterized.  In this presentation, I will discuss the research my students and I have been conducting to characterize precipitation temporal clustering and flood spatial scaling.  We developed an index to quantify precipitation clustering that can be used to evaluate changes in precipitation distributions that may affect floods and baseflow.  We have also examined spatial variations in flood magnitudes within river basins of varying morphology as a context in which changes in flood magnitude arising from land-use or climatic changes can be examined.

Speaker Bio:
Dr. Karen Prestegaard is an Associate Professor in the Department of Geology at the University of Maryland. After earning her PhD in Geology from the University of California, Berkeley in 1982, she has studied hydrological processes including sediment transport and depositional processes in mountain gravel-bed streams; mechanisms of streamflow generation and their variations with watershed scale, geology, and land use; hydrologic behavior of frozen ground; hydrologic consequences of climate change and the hydrology of coastal and riparian wetlands.
