KSU Watershed group graduate students Vladimir Karimov, Gia Nguyen, Tobias Oker and an undergraduate research assistant Reggeany Friesen presented their research at the 2016 Student Water Conference on March, 24-25 at Oklahoma State University. Vladimir presented results on the impacts of precipitation patterns on ephemeral gully erosion processes. Gia showed his findings on water productivity of mobile drip irrigation technology. Reggeany presented results on soil erodibility testing under different soil moisture content with JET. Tobias showed critical sources of sediment in the Little Arkansas Watershed. Great job by all young researchers!

The workshop gathered 24 participants from five universities, who were interested in testing soil erodibility parameters with JET. The speakers included experts Dr. Garey Fox from Oklahoma State University and Dr. Erin Daly from Abraham Baldwin Agricultural College. The first day focused on theoretical background and methods, while JETs were ran at Campus creek in day two.

We presented our work on impacts of variability of climate datasets on watershed hydrology under changing climate at the ASABE 1st Climate Change Symposium: Adaptation and Mitigation in Chicago, IL. The study related to capturing climate variability predicted by NEXRAD, PRISM, and NCDC in the Smoky Hill watershed in western Kansas and how it impacts SWAT model results under different climate scenarios.
