Hinkle, Nicole AdrieneThis thesis proposes a center and attendant water cleansing systems that will simultaneously cleanse the waterways of the Potomac River in Washington D.C. through filtration and the removal of aqueous impurities as well as hosting research and exhibitions demonstrating ways humans can successfully improve the earths natural watershed systems. This particular example in our nation's capital will also provide recreation and education space for the community to learn about the health of water systems and feature global strategies to improve our watersheds in the symbolic landscape of the national mall and surrounding monumental landscape.enThesisArchitecturecleansingPotomacresearchriverwaterwetlands
