INNOVATIVE AND BENEFICIAL USE OF DREDGED MATERIAL FOR STORMWATER MANAGEMENT Muhammed Bahcetepe | Advisor: Rui Liu, Assistant Professor, College of Architecture and Environmental Design, Kent State University BACKGROUND More than 1.5 million cubic yard (CY) sediment needs to be removed annually from fifteen federal harbors, and smaller ports for recreational navigation along the Ohio’s Lake Erie coast. Devaluation and destabilization of neighborhoods around the unremediated brownfields, and the impervious surface increases flooding concerns in combined sewer overflow areas where many brownfields are located. Green infrastructure (GI), e.g. green roof, rain gardens, emphasizes infiltration and hydrological retention, and could potentially provide a flexible and affordable solution to remediate urban brownfield in Cleveland. The dredged material may supply nutrients for plant growth in GI and raw mineral materials for aggregate production, which has high hydrological retention capacity for GI construction. Confined Disposal Facility in Cleveland is currently the only place to store dredged material in Ohio. INNOVATION OF THE PROJECT RESEARCH OBJECTIVES • To evaluate the suitability of dredged material from Cleveland Harbor for use in green infrastructure e.g. green roof, rain garden etc in brownfield remediation. The innovation in this study is to sinter(bake) the dredged material under different temperatures, and with different proportions of ingredients. • To prepare and produce “green” aggregate with high porous surface and inner microstructure, which is made from dredged materials and possibly other mineral admixtures such as fly ash. In Cleveland there are over 14,000 acres of brownfields with over 90% impervious surface.
