Consolidation Performance of Soft Clays: Part 2. Predictions
The simplified version of the model described in Part 1 was used to predict the short-term performance of the St. Alban test fill. The long-term predictive capability of the model was...
Consolidation of Multi-layered Clay
Three kinds of clay with different plasticity were pre-consolidated from slurry and combined into typical two layered systems consolidated under 40 tf/m**2 with single drainage condition....
Consolidation by Sand Drain in Anisotropic Ground
The author reduces Biot's equations of consolidation into a single governing equation with the excess pore water pressure as the only unknown function and derives the theory...
Perspectives on Modelling Consolidation of Dredged Materials
The physical and mathematical aspects of this problem are highly nonlinear and material-property relationships extend beyond the scope of standard geotechnical engineering. The potential...
Instrumentation Performance in Soft Clay Soils (A Case History)
In 1978, IDEAL BASIC INDUSTRIES, INC. initiated construction of a cement manufacturing plant located south of Mobile, Alabama on the Theodore Ship Channel. Because deltaic clays were too...
Charlotte Harbor Beach Nourishment
The project consisted of dredging approximately 300,000 cubic yards (229, 380 cubic meters) of material, utilizing a seagoing hopper dredge, from the entrance channel of Charlotte Harbor,...
Management Plan for Dredged Maintenance Material
The Mobile District Corps of Engineers is responsible for the maintenance of an authorized Federal deep-draft navigation project at Pascagoula Harbor, Mississippi. The development of the...
Modeling the Drying of Dredged Material
The drying of dredged material was modeled mathematically as a diffusive process and the governing equation was solved using an integral method. Closed form solution equations are presented...
Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...
Plant Bioassay of Contaminated Dredged Material
Contaminant mobility from a contaminated saltwater sediment placed in flooded and upland disposal conditions was studied in the greenhouse. Spartina alterniflora was grown in contaminated...
A Biogeochemical Evaluation of Disposal Options
This paper briefly reviews some of the factors that should be considered in selecting an environmentally sound disposal method for contaminated sediments on the basis of the biogeochemical...
Evapoconsolidation in Fine-grained Material
The increased difficulty of obtaining land needed for confined disposal of dredged material and phosphatic clays highlights the need to assess alternative disposal measures by accurately...
Safe Landfilling of Contaminated Dredging Spoil
This paper deals with the assessment of the expected emissions of toxic substances from highly contaminated harbor dredged material. The material in question arises from the canal between...
Aquatic Bioassays in Dredged Material Management
Dredged material ranges from gravel and coarse sand to fine silts and clays, and may be free of contaminants or highly contaminated with a variety of chemicals from industrial, municipal,...
Abrasion Resistance of Polyethylene Dredge Pipe
In recent years there has been a slow but steady increase in the number of dredges using high density polyethylene (HDPE) pipe in discharge lines. HDPE's increased popularity...
Settling of Dredged Material Slurries
Most environmental engineers, accustomed to dealing with clarification of suspensions containing approximately 150 mg/1, find it difficult to comprehend dredged material slurries, in which...
Current Issues in Rock Dredging
An attractive alternative to the use of explosives for deepening shipping channels is the improvement of the rock cutter suction dredger. But, assessing the capability and design parameters...
Accurate Computation of Nonlinear Advection
Advection, the transport of a quantity by the mean velocity, is a process which appears in virtually all equations of free-surface hydraulics. The demonstrated accuracy and efficiency...
Local Scour at Fish Rocks
There is a growing interest in the enhancement of rearing habitat for juvenile anadromous fish in the Pacific Northwest. This has focused attention on the need for a better understanding...
Leaching Analysis of Coal Mine Spoil Material
Arch Mineral Corporation has conducted a column leaching study to analyze the leaching characteristics of surface coal mine spoil material in order to predict post-mining groundwater quality....
