This book was released on 1978 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a study undertaken to determine the volumetric requirements of a confined disposal site filled with fine-grained dredged material. The method of study required a three-phase approach. The first phase was the evaluation of previous work and the formulation of a new prediction methodology based on modified consolidation theory and standard weight-volume relationships used in geotechnical engineering. The second phase consisted of developing the proposed prediction methodology. The final phase consisted of correlating the volume increase predicted by the proposed methodology with the rate of volume increase measured under field conditions. Also included in the final phase was the creation of a computer program based on the prediction methodology developed during the study. The computer program was developed for the purpose of evaluating the effect of various input variables on the gain in available storage volume. Since the program was designed for applicability over a large range of conditions, the results obtained from the computer program are site-specific.

This book was released on 1983 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report documents studies refining the procedures for calculation of one-dimensional consolidation behavior of very soft fine-grained dredged material. Both the conventional small strain theory of consolidation, which requires linear or constant soil properties, and the more general finite strain theory, which provides for nonlinear soil properties, are presented. Implications of the simplifying assumptions necessary in practical application of the theories are discussed and the general finite strain theory is shown to be superior for the treatment of dredged material. The governing equations for both theories are written in nondimensional terms and appropriate boundary and initial conditions are specified. Solutions in terms of figures relating the percent consolidation to the nondimensional time factor for small strain theory have been previously published. However, similar solutions based on the finite strain theory were not available and thus had to be developed. Using a computer program, a linearized nondimensional form of the general finite strain governing equation was solved for the cases of singly/doubly drained normally consolidated clays, and singly/doubly drained dredged fill. The figures given represent a significant advancement in the ability to accurately predict the consolidation behavior of thick deposits of very soft fine-grained materials having nonlinear soil properties. A method of obtaining soil parameters necessary for use of the new solution charts is proposed. (Author).

This book was released on 1978 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The suspended solids concentration in the effluent water from an upland containment area being filled with fine-grained dredged material can be significantly influenced by the length of the weir and the depth of the ponded water. This study develops a procedure for designing and operating the weir to maintain good effluent quality, given a flow and dredged material type. Stratified-flow and sediment-transport models were investigated to describe the depth of withdrawal, velocity profile, and effluent suspended solids concentration, given a concentration profile and flow. Field data on these parameters were collected at three sites--Yazoo River, MS, Fowl River, AL, and Oyster Bay, AL. The Waterways Experiment Station's selective withdrawal model developed by Bohan and Grace, modified to fit observed data, was selected as the basis of the design procedure. Using this model, nomograms were developed for the design procedure for silt and saltwater clays and for freshwater clays. The nomogram relates the flow, weir length, ponding depth, and effluent suspended solids concentration. The designer manipulates these four variables until he reaches a satisfactory balance between weir length and ponding depth, based on his design flow effluent goal. Sharp-crested rectangular or shaft-type weirs are recommended.
