Hydrologic Landscapes of the Western U.S.

Hydrologic Landscapes of the Western U.S.

Salt River, Arizona from landscapes (HLs) have been an active area of research for the Pacific Northwest (PNW) and across the U.S. to determine whether this concept can be used to make spatially distributed assessments of streamflow variability or potential climatic response at statewide and regional scales [Winter (2001), Wolock (2004), Wigington (2013), Patil (2014), Leibowitz (2014), Comeleo (2014)]. Wolock et al. (2004) developed HLs for the contiguous 48 states of the U.S., but higher resolution data was available regionally for some portions of the U.S. Wigington et al. (2013) generated spatially distributed HLs for Oregon using the highest quality data available for the state. At present, Wigington et al. (in progress) has been developing HLs across the tri-state PNW (Oregon, Washington, and Idaho) region using updated methods that utilize data of varying resolution across state boundaries. In this project, I am using HLs across the southwestern U.S. (defined as California, Arizona, and Nevada) to develop hydrologic vulnerability indices. I am also examining how changes in drought vulnerability are impacted by historical and future changes in climate (temperature and precipitation).
