Abstract
Grand Valley State University was founded in 1960 and since then over 120 acres of impermeable surfaces, runoff from which was channeled into the ravines, have been constructed. This resulted in erosion, slope instability, and sediment discharge into the Grand River. As part of the June, 2011 library construction project, stormwater runoff from impermeable surfaces was redirected from the Little Mac Ravine to a new wetland west of campus. In order to observe how runoff diversion alters certain water quality parameters, water samples were collected from the Little Mac ravine throughout the summer of 2011. Different surfaces in the Little Mac ravine watershed affect runoff and stream discharge and will be mapped using a Geographic Information System (GIS), aerial photos, and LIDAR topographic data. The rational runoff equation, combined with watershed surface delineation, will allow for a semi-quantitative analysis of peak discharge changes resulting from 2011 storm water diversion.
