Book excerpt: The influence of meteorological conditions and the physical, chemical, and mineralogical properties of fine-grained dredged material on the formation of crusts resulting from evaporative drying in confinement areas was evaluated. After decantation, the moisture content of the surface layer is equivalent to about 2.5 times the liquid limit. Evaporation of moisture during the first stage of drying is nearly the same as that from an open pan until the moisture content decreases to about 1.8 times the liquid limit. After this, drying proceeds at a rate dependent on the transport of moisture to the surface. As the material desiccates, surface cracks open. The volume shrinkage is equivalent to the volume of water evaporated as the crust forms, and evidence is given that the volume change is irreversible. Rainfall is shed from the crust and drains into the cracks, from which it can run off if channels are provided to the outflow weir. Management practices, including stirring and the removal of a thin layer of crust, produced only small increases in evaporation rate for a few days. Systems were developed to dig drainage trenches in the confinements and to remove the consolidated crust. A small dredge appears to offer the most promise for cutting deep or wide surface drainage ditches.

Book Synopsis Management Plan for the Disposal of Contaminated Material in the Craney Island Dredged Material Management Area by :
Download or read book Management Plan for the Disposal of Contaminated Material in the Craney Island Dredged Material Management Area written by and published by . This book was released on 1993 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Craney Island Management Plan was developed to extend the life of the Craney Island Dredged Material Management Area (CIDMMA). The CIDMMA is used to dispose maintenance and new work dredged material from the project area. With current practice, CIDMMA would reach ultimate capacity by the year 2000. If, however, suitable material is barged to the sea and only contaminated material is placed in the facility (Restricted Use Program), then the life of the facility can be extended. Two tasks were addressed in this study: (a) determine service life under Restricted Use and (b) determine contaminant losses and conduct a Comprehensive Analysis of Migration Pathways (CAMP) expected to occur under Restricted Use. The results showed that the service life of the CIDMMA could be extended under Restrictive Use for approximately 140 years under baseline coniditions or 90 years under Worst Case conditions. The CAMP analysis was conducted along three major contaminant migration pathways (effluent, leachate, and volatile). Effluent was the most significant pathway for metal losses and volatilisation and for polynuclear aromatic hydrocarbon (PAH) losses. Leachate losses under a fully dewatered condition would not exceed effluent losses for some metals. PAH losses for a fully dewatered condition would not exceed effluent losses.

Book Synopsis Geotechnics of High Water Content Materials by : Tuncer B. Edil
Download or read book Geotechnics of High Water Content Materials written by Tuncer B. Edil and published by ASTM International. This book was released on 2000 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reasonable estimates indicate that approximately a billion cubic meters of high water content soil-like wastes are produced annually worldwide, and a large portion of these are deposited hydraulically in diked impoundment areas, some of which are among the largest earth structures in the world. The major problems emanating from this disposal method are the difficulty in dewatering the wastes, their low strength and hydraulic conductivity, their high compressibility, their potential to contaminate the groundwater, the stability of the confining dikes, and the ultimate reclamation of the disturbed land. Following a brief explanation of how many of these wastes are generated, quantitative values for key engineering properties are summarized and compared for a wide variety of waste materials and some reference soils. Then, many concepts that have been applied with success will be presented together with the advantages each offers, the difficulties involved in using it, and the limitations in our knowledge. Discussed briefly will be state-of-practice developments in mathematical modeling, laboratory testing and associated interpretations, and material property formulations.

Download or read book An Evaluation of Progressive Trenching as a Technique for Dewatering Fine-grained Dredged Material written by Michael R. Palermo and published by . This book was released on 1977 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a study conducted within a confined disposal area concerning the effects of progressive trenching on dredged material dewatering and drying are documented. The study consisted of an initial field and laboratory testing program, construction of a surface drainage system within the disposal area using a progressive trenching approach, evaluation of trenching equipment, and a field instrumentation and monitoring program. Effects of the progressive trenching efforts were evaluated by monitoring dredged material surface elevations and dredged material groundwater elevations within the study area. Field data indicated that the surface drainage system was effective in lowering the dredged material groundwater table. An average surface settlement of approximately 0.75 ft was achieved throughout the study area. Economic evaluations indicated that progressive trenching operations were economically feasible with both comparatively low unit cost and favorable benefit/cost ratio.
