Dr. Naomi Tague and PhD students Kyongho Son and Xiaoli Chen attended the CUAHSI Fourth Biennial Colloquium on Hydrologic Science and Engineering – “Water Across the Critical Zone: Scaling from Local to Global Hydrology” – July 28-30, 2014, at the National Conservation Training Center in Shepherdstown, WV.

Kyongho Son presented “Effect of soil parameter uncertainty on assessing climate change projection in two small Sierra Nevada watersheds”, covering the key points: 1) Model estimates for a transient snow watershed has higher predictive uncertainty for streamflow, evapotranspiration and net primary productivity than those for a snow-dominated watershed; 2) The effect of soil parameter uncertainty is larger in the drier years and summer; and 3) Accounting for soil parameter uncertainty in modeling for climate impact analysis is necessary.

Xiaoli Chen presented “Modeling Nitrate Exporting Patterns during Storm Events for a Semi-arid Mountain Watershed”, explaining how we downscale a daily version of the RHESSys model to an hourly version, and how we implement ”fill and spill” in RHESSys.
