From spring 2015 to winter 2016, faculty and students from Calvin College worked together to create a hydrologic model of the Plaster Creek watershed using the United States Army Corps of Engineers software, “Hydrologic Engineering Center Hydrologic Modeling System” (HEC-HMS), as part of a 319 Grant from the Michigan Department of Environmental Quality (MDEQ). Professor Robert Hoeksema, PhD, Professor Julie Wildschut, P.E., and student research assistant Ryan De Groot comprised the hydrology team for this project. The purpose of this project was to create a model that would highlight the trouble areas of the watershed, those that contribute excessive amounts of runoff to the creek, and to help Plaster Creek Stewards plan where Best Management Practices (BMPs) could be installed to help improve the quality of the water in Plaster Creek. The model will also allow users to estimate the changes within the watershed due to the installation of various BMPs.
