Seven regional DMRP studies were conducted throughout Corps of Engineers maintained waterways to determine dredged material island use by nesting waterbirds and the succession of vegetation on these islands as affected by bird use, to compare diked and undiked islands and natural and man-made islands and sites, and to study migratory and year-round use of dredged material islands. These data and pertinent management information are synthesized in this report. Recommendations and guidelines for management of existing dredged material islands and creation of new islands are set forth by the authors. Five major factors determining selection for waterbird colony sites on dredged material islands are set forth: isolation from predators and humans, habitat diversity, nesting substrate stability, species behavioral characteristics, and species feeding and foraging habits. Management for waterbird colonies has been proven feasible and may be accomplished by several important facotrs: (a) incorporation of management plans into routine dredging operations, (b) interagency and intraagency cooperation, and (c) public education and cooperation. It was determined that dredged material islands are often crucial habitat for colonial waterbirds and should be maintained and managed as such. (Author).

A 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 Techn disposal models (developped 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 date 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 th US Army Engineer Waterways Experiment Station and presents calibration results using field data from the Duwamish, New York Bight, and Lake Ontario disposal sites. In addtition, 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 Techn 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 present 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 elements models. In addtion, limitations of the models and their current status are discussed.
