Villa Angela beach in Northeast Ohio has been closed multiple times over the past decade due to high influxes of E. Coli bacteria. Problems often arise after large rain storms due to the flooding of multiple combined sewer overflow systems feeding into the streams of the Euclid Creek watershed and being deposited off the shore of the beach. This project is an attempt to use discharge data to assess times of high flow and assess the content and contamination influx of these dates using specific remote sensing techniques. Landsat-8 images were combined with the KSU spectral decomposition method of image analysis, which employs varimax-rotated principal component analysis (VPCA) to determine the main contributors to the water’s overall content and their interaction with the aquatic systems in the lake and around the mouth of the creek. This more cost- and time-effective method can reduce potential biases in traditional remote sensing techniques by separating individual components based on their respective spectral fingerprints and comparing against a known library of spectra.
