Stabilization Of Dredged Materials In Ohio: An Investigation Of Mechanical, Chemical And Biological Dewatering Techniques, Erika Howard Jan 2019

Stabilization Of Dredged Materials In Ohio: An Investigation Of Mechanical, Chemical And Biological Dewatering Techniques, Erika Howard

Williams Honors College, Honors Research Projects

Each year, materials are excavated from oceans and lakes in order to keep the waterways open so that ships can safely pass through. These excavated, or dredged, materials are then discarded, usually being returned to the body of water from which they were removed. Beginning in 2020, the Ohio Environmental Protection Agency (OEPA) will no longer allow this to occur. Therefore, the purpose of this project is to investigate beneficial uses for dredged materials in Lake Erie, and to address the best management practices for dewatering these materials, as set forth in the Lake Erie Protection and Restoration Plan created ...


Investigation Of Dredge Material Dewatering Through Hydraulic And Ground Improvement Methods, Monica Moody Jan 2019

Investigation Of Dredge Material Dewatering Through Hydraulic And Ground Improvement Methods, Monica Moody

Williams Honors College, Honors Research Projects

Every year almost 1.5 million tons of material is dredged from Lake Erie to allow passage for boat traffic. In the past, this material has been placed back into the open waters of the lake. However, starting July 2020 this will no long be permitted due to the passing of Senate Bill 1. Therefore, secondary uses of this dredging material are being investigated. To be used, the material needs to be quickly dewatered and stabilized. This project consists of literary reviews of two methods of rapid dewatering, hydraulic placement and ground improvement methods. Hydraulic placement dewatering requires the use ...
