Hydro-Kansas Research Project: Multi-Scale Dynamical Understanding Of Statistical Scale Invariance In Floods And Riparian Evapotranspiration In River Networks

Aug. 21, 2018

Gupta , Vijay 1 1 CEAE Abstract The Hydro-Kansas (HK) is a multi-institutional, multi-investigator, multi-disciplinary research project. It represents the first illustrative example of a Natural Laboratory (NL), as described in the Water, Earth, Biota (WEB) report to the National Science Foundation ( http://cires.colorado.edu/hydrology ). HK combines theoretical analyses, numerical...

Hydrology At The Bottom Of The World - A Key Influence Of Ecosystem Dynamics In The McMurdo Dry Valleys, Antarctica

Aug. 21, 2018

Gooseff , Michael 1 1 Penn State University In numerous extreme environments on Earth, the notion that ā€œwhere there is water, there is lifeā€ has generally held. The ā€˜barrenā€™ landscape of the McMurdo Dry Valleys, Antarctica, characterized by harsh conditions (e.g., air temperature ranges from <-40ā°C to >0ā°C), is no...

Non-Parametric Paleo-Reconstruction Of Lees Ferry Annual Streamflow Ensembles

Aug. 21, 2018

Gangopadhyay , Subhrendu 1 1 AMEC Hydrosphere A non-parametric method for paleohydrologic reconstruction (NPP) of streamflows using tree-ring chronologies is developed. The method uses pattern matching of chronologies in EOF-space (Empirical Orthogonal Function) to identify a set of K-nearest neighbors (similar years) from a contemporary period (common period of tree-ring...

The Impact Of Bed Disturbance On The Growth Of The Nuisance Diatom Didymosphenia Geminata In Boulder Creek

Aug. 21, 2018

Cullis , James D 1 ; Miller , Mathew 2 ; McKnight , Diane 3 1 University of Colorado 2 Penn State University 3 University of Colorado Didymosphenia geminata, or ā€œrock-snotā€, is a nuisance diatom species that can form large amounts of stalk material that covers the streambed. These blooms...

How Water In Extreme Locations Helps To Control The Current Climate On Mars

Aug. 21, 2018

Brown , Adrian 1 1 NASA Ames The Martian poles are the most dynamic regions on the Red Planet, changing almost daily, and exchanging icy material between each pole as the surface warms or cools with the season. Two ices freeze and thaw as part of this cycle - CO2...
