ADDAMS Application: Hydrologie Evaluation of Leachate Production and Quality (HELPQ) Module in CDFs
PURPOSE: This technical note describes the application of the Hydrologie Evaluation of Leachate Production and Quality (HELPQ) computer program, which facilitates the design of confined disposal facilities (CDFs) for contaminated dredged material by estimating leachate production rates and leachate quality. HELPQ is part of the Automated Dredging and Disposal Alternatives Modeling System (ADDAMS).
متن کاملERDC TN-DOER-R3, "Validating Pathway Analysis of Organic Contaminants from Aged Dredged Material Using Plants and Worms"
PURPOSE: Contaminants in dredged material (DM) placed in an upland situation, such as a confined disposal facility (CDF), may move from substrates into food webs because of their contact with CDF-colonizing or –inhabiting plants and animals, and therefore may cause unacceptable risks outside the CDF. The primary goal of this technical note is to provide guidance on evaluating bioaccumulation of...
متن کاملERDC/EL TR-14-1 "Taxonomic Evaluation of Cleveland Harbor Lake Areas"
The U.S. Army Corps of Engineers (USACE) performs routine maintenance dredging of federal navigation channels. Prior to dredging, an evaluation of the dredged material may be needed to determine the best management alternative. A dredging evaluation involves chemical and biological analysis to determine the potential impacts of the dredged material in both the water column during placement and ...
متن کاملDesigning Low Impact Wastewater Discharge from Solar Distillation Site to Sea
Dry areas near the sea can obtain fresh water through solar distillation of saline sea water resources. However, these solar distillation sites produce wastewater as a result of desalination of sea water with high salt concentration. Waste must be disposed of with the least effect on the receiving environment (sea, in most cases). Initial dilution and its characteristics play important roles in...
متن کاملTransport of Dredged Sediments after Disposal Operation in Lake Erie
A dredged material disposal operation was monitored on a location in Lake Erie 8 km offshore Ashtabula, Ohio, June to November, 1975. Some 200 sediment cores were collected in the periods before and after dredging and analyzed for the grain-size distribution of the sediments. Two current meters and a wave sensor moored nearby monitored the movement of the water masses. The sediments were dredge...
