Service-Learning In Action: Lafayette, Indiana, Rain Garden Installation, Elizabeth Mccleery

Purdue Journal of Service-Learning and International Engagement

Indiana’s Wabash River is being polluted with contaminated water runoff from precipitation events. A lack of pervious land cover has led to an accumulation of fertilizer, sediment, and waste in the river. Green infrastructure, a stormwater management practice that mimics the natural ecosystem, is one of the most effective ways to prevent pollution from stormwater runoff and benefit the community. This project consisted of a rain garden installation at the Lafayette Fueling Station, a site where frequent water drainage and water runoff into the Wabash occurs. The rain garden will allow on-site water infiltration during rain events and promote natural …

Solar-Powered Microgrids In Northern California: An Opportunity For Resilience, Marina Riddle

Master's Projects and Capstones

Planned and unplanned power outages have been increasing in frequency and duration, negatively impacting all public sectors, and threatening public safety. These outages are deadly to those who rely on medical devices. As climate change-fueled extreme weather events (wildfires, earthquakes, storms, etc.) also increase in frequency, our electrical grid must be prepared to bounce back. Microgrids provide necessary redundancy and reliability. Through a novel GIS suitability analysis, based on solar radiation, land use type, local energy demand, distance to transmission lines, distance to roads, and slope, optimal locations for solar-powered microgrids throughout Northern California were determined.
