INVITED KEYNOTE PRESENTATION: Hydrological Processes Inferred From Geochemical Data -- Or Vice-Versa?

Aug. 23, 2018

Hornberger , George M. 1 1 University of Virginia Understanding the mechanisms by which rainfall is transformed into streamflow in forested catchments is a key prerequisite to understanding pollutant transport, biogeochemical cycles, and aquatic ecosystem functioning. Geochemical tracers often are used to infer water flowpaths and residence times in upland...

Numerical Simulations Of Vortex Stirring Associated With Fertilization Efficiency In Marine Invertebrates

Aug. 23, 2018

Hartford , Jillian R 1 ; Crimaldi , John P 2 1 University of Colorado--Â鶹ӰԺ 2 University of Colorado--Â鶹ӰԺ Various benthic invertebrates (e.g. sea urchins, anemones, corals) rely on broadcast spawning, a fertilization strategy whereby male and female adults simultaneously release sperm and egg into the surrounding flow [1]. In...

Inverse Modeling Of Soil Hydraulic Properties From Surface Temperature

Aug. 23, 2018

Gutmann , Ethan D 1 ; Small , Eric E 2 1 University of Colorado 2 University of Colorado Soil Hydraulic Properties (SHPs) play an important role in regulating heat and moisture fluxes in land surface models. Currently, SHPs are estimated from soil texture class. However, studies have shown that...

INVITED KEYNOTE PRESENTATION: Integration Of Science And Decision Making For Watershed Management: Reducing The Uncertainty Of Key Water Balance Components At The Basin Scale.

Aug. 23, 2018

Goodrich , David C. 1 1 USDA-Agricultural Research Service, Tucson Decision-makers and natural resource managers increasingly require much more sophisticated levels of expert findings and scientific results to make informed decisions. No single scientific discipline is typically capable of providing integrated solution for decision-makers and managers. Significant effort beyond the...

INVITED TALK: Hydroclimatology Of The North American Monsoon: Bound By Terrain But Courted By ENSO?

Aug. 23, 2018

Gochis , David J 1 1 National Center for Atmospheric Research Research into the North American Monsoon reveals a continental-scale climatic system possessing marked intra- and inter-regional variations in hydroclimatology. Some works have elucidated the striking role that regional physiography (e.g. terrain and proximity to water bodies) within the monsoon...
