Abstract : The feasibility of performing laboratory experiments to aid in the modification and enhancement of existing numerical models for predicting the physical fate of dredged material discharged into open water is addressed. First, appropriate scaling laws are investigated to determine if prototype dredged material disposal behavior can be accurately simulated in a physical test facility for various cohesive and noncohesive sediments. Information gained from this investigation is used to determine the general design requirements of the test facility. These requirements include the types of equipment and measurement techniques required to monitor rates of cloud entrainment, rates of spreading on the bottom, disposal material properties, suspended sediment concentrations, and other parameters of interest. Typical testing scenarios for various discharge conditions are included.
