dc.descriptionTechnical Report-
dc.description.abstractA summary of the results from three work units (1B06, 1B07, and 1B09) of the Dredged Material Research Program, concerned with predicting and monitoring dredged material movement, is presented. Work Units 1B06 and 1B09 were concerned with the prediction of the short-term fate of dredged material discharged in open water. In particular, 1B06 was an evaluation and calibration of the Tetra Tech disposal models (developed under Work Unit 1B02 of the DMRP by Tetra Tech, Inc.) using field data collected at several disposal sites, including the Duwamish, New York Bight, and Lake Ontario sites. The collection of these field data was performed under Work Unit 1B09 by Yale University. Work Unit 1B07 involved an evaluation of two two dimensional finite element models (developed under Work Unit 1B05 of the DMRP by the University of California at Davis) for the long-term prediction of sediment transport in estuaries. Part II of the report discusses the modifications of the Tetra Tech models made by the U.S. Army Engineer Waterways Experiment Station and presents calibration results using field data from the Duwamish, New York Bight, and Lake Ontario disposal sites. In addition, a summary of observations from a field data collection program on the mechanics of the placement of dredged material at open-water disposal sites is presented. Major conclusions noted are a.) The Tetra Tech models should only be used in a qualitative sense until knowledge of the required coefficients is improved. b.) Proper material characterization is extremely important in obtaining realistic predictions from the models. c.) Entrainment and drag coefficients in the descent and collapse phases appear to be the most sensitive coefficients in the models. Part III of the report presents a discussion of the factors involved in the long-term transport of sediment in estuaries and how they are handled by finite element models. In addition, limitations of the models and their current status are discussed.-
