Measuring and Modeling Hydrologic Fluxes and States from Aquifer to Atmosphere at Multiple Scales
Abstract
This project made advances in data assimilation and modeling capabilities for predicting soil moisture states and fluxes at the sub-watershed scale by using calibration information from a network of high-quality observation sources at a range of scales including remote sensing data and field sites. The sub-watershed is the semiarid mountain front above Boise, Idaho which has two well-characterized field sites (Boise Hydrogeophysical Research Site, BHRS, a riparian setting at the base river boundary of the block, and Dry Creek Experimental Watershed, DCEW, spanning open to forested slopes to the crest of the block). We have added instrumentation and monitored saturated and partially saturated moisture behavior between river, aquifer, vadose zone, and atmosphere at the BHRS to quantify fluxes and support direct and noninvasive geophysical (especially radar and electrical) method development for measuring moisture and physical properties and their spatiotemporal variations at high resolution. Similar activities have taken place at the DCEW as well as model developments and assessments of DCEW data on the ground and from satellites for validation and verification in data assimilation including downscaling of fractional snow cover and slope-aspect moisture regimes. Students and collaborators (within Boise State and extramural) are involved in all aspects of this project.
