The Theory of One-Dimensional Consolidation of Saturated Clays
The theory of nonlinear finite strain consolidation is reviewed. A modification of the effective stress equation to account of settling and consolidation as a unified phenomenon is proposed....

Particle Interaction and Stability of Suspended Solids
The physics of particle interaction, which is responsible for the problem of the apparent tardy settling of suspended solids in tailings discharge slurries containing initially low concentrations...

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 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...

Consolidation of Mining Wastes
This paper describes laboratory and field tests for determining consolidation properties of soft sediments, presents data on several types of mining wastes, and presents the results of...

Time and Stress Dependent Compression in Soft Sediments
Results are presented for laboratory experiments using a typical estuarine mud settling from a slurry in columns of 100mm diameter. Measurements have been made of density and pore water...

Prediction of Viable Tailings Disposal Methods
A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for...

Centrifugal Modeling of Phosphatic Clay Consolidation
As a by-product of beneficiation, quantities of dilute clay slurry are produced which are stored in retention ponds. One method of accelerating consolidation is to surcharge the clay with...

Application of Finite Strain Consolidation Theory for Engineering Design and Environmental Planning of Mine Tailings Impoundments
A knowledge of the consolidation behavior of mine tailings, during and after deposition, is important in estimating final impoundment capacity, rate and pore fluid expulsion during and...

Convection-Diffusion Analysis of Sedimentation in Initially Dilute Solids-Suspensions
The settling of suspended solids in solids-suspensions is treated from the viewpoint of the relative fluxes established as a result of the upward diffusion of water and the downward convection...

Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...

New Tools Help Find Flaws
Certain electromagnetic tools for nondestructive evaluation of existing infrastructure, though not widely used, can cut cost and time of identifying flaws in existing infrastructure. Five...

Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...

Infrastructure: Money and Methods
State and local governments have started to cope with their infrastructure problems by passing bond issues, establishing infrastructure banks to centralize resources and decision making,...

Selecting an Economical Water Main Rehab
Many miles of aging water mains exist with carrying capacities that are less than half of what they were when new. Engineers must, therefore, stretch every dollar to eliminate deposits...

Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...

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...

Land Application of Dredged Material at Port Manatee
Maintenance dredging of approximately 600,000 cu yd of highly plastic clay was conducted in October 1983. This material was deposited on a nearly 200 acre tract of farmland in a depth...

Long-Term Planning for Dredged Material Disposal
The dredged material produced from maintenance of the channel in Upper Mobile Harbor (UMH) is disposed into confined upland disposal areas provided by the project's local...

Long-Term Maintenance Dredging Permits - Florida's New Approach to Regulation
Previous approaches to regulating maintenance dredging activities in Florida generally have been myopic and failed to gather information that adequately reflects the needs for environmental...
