Evaluation of Disposal Areas in James River; Hydraulic Model Investigation.
Abstract
The existing comprehensive fixed-bed model of James River was used to study the major disposal areas used during maintenance dredging operations for the existing 25-ft-deep navigation channel to determine if the disposal areas are performing satisfactorily in terms of retaining dredged material placed therein. If the test results indicated a probable excessive rate of return of dredged material to the channel, the tests were expanded to include studies of an alternate area or areas in the same general vicinity to determine if a more suitable disposal area could be defined. The tests consisted of the release of lightweight sediments at surface depth in the disposal areas, tracing patterns of movement of material from the areas, and defining areas where these sediments would probably deposit. The results indicated that, in general, the disposal areas and operating procedures presently employed are satisfactory with respect to areas of material deposition and material retention characteristics.
