Abstract : The US Army Corps of Engineers is considering the initiation of five research areas directed toward improving analytical methods and field monitoring procedures related to the physical aspects of disposing and confining contaminated dredged material. These research initiatives are: (a). Evaluation of critical shear stress. Theoretical and mathematical investigations will be conducted to develop the best methodology for calculating shear stress. Field measurements will be performed to obtain data sets for verification of theoretical results. (b). Fate and stability of dredged material disposed in open waters. This research will involve an ensemble of existing numerical models in developing a standard application framework for simulating the hydrodynamic/sediment interactions in offshore and estuarial environments. Standardized techniques and equipment will be developed for monitoring open-water disposal sites. (c). Suitability of material for capping contaminated dredged material. Research will combine integrated field tests and physical and numerical model investigations to establish a standard methodology for the design and placement of stable caps under varying physical, chemical, and biological conditions.
