Stress on natural resources in urban areas has been increasing continuously in proportion to increasing urban density. Managing water resources through an ecotechnological approach is important for stormwater management and water pollution mitigation. Retrofitting existing infrastructure by well-established Green Infrastructure (GI) combined with emerging technological advancements in informational system can provide a sustainable solution for managing urban water resources. In such effort, our research is exploring application of GI retrofit integrated with upgrade of ponds with remote sensing and artificial intelligence support systems for their optimized operation. For example, our retrofit study for an urban area has projected to reduce runoff volume for a one-inch rain event by 29% on annual basis. Our poster will present details of our study area, our approach for GI retrofit of non-point source areas and retrofit of a pond for automatic operation based on weather forecast. In addition, we will present our hydraulic modeling simulation model set-up and results.
