USRWA & UW-Whitewater to bring Watershed Modeling to the Upper Sugar River


In an exciting new partnership with Upper Sugar River Watershed Association and UW-Whitewater, geography students from Professor Dale Splinter’s class will be working to create an Erosion Vulnerability Assessment for Agricultural Lands (EVAAL) model for the watershed. The EVAAL model allows USRWA to better assist farmers who are looking to limit runoff from their fields, including phosphorus.

Developed by the Wisconsin Department of Natural Resources, the EVAAL model evaluates locations of relative vulnerability to sheet, rill and gully erosion using information about topography, soils, rainfall and land cover. This tool enables watershed managers to prioritize and focus field-scale data collection efforts, thus saving time and money while increasing the probability of locating fields with high sediment and nutrient export for implementation of best management practices.

UW-Whitewater students will be working on this project during the Fall 2015 semester and hope to present their findings in December 2015. USRWA thanks Professor Splinter for this beneficial collaboration.
