Predicting Overland Flow and Infiltration
The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply...

An Infiltration Based Runoff Model For Use With a Design Store
The feasibility of using an infiltration approach for routine runoff prediction has become a reality with the development of approximate infiltration models based on physical principles...

The Upstream Zone in Concrete-Face Rockfill Dams
The upstream zone of small rock, the supporting zone for the slab at many recent concrete-face rockfill dams has contained less than 20% of particles smaller than the No. 4 sieve. Such...

Numerical Analysis of Two Embankment Foundations
Two case histories of the performance of a compressible embankment foundation are analyzed using the Cam-Clay constitutive model and a finite element consolidation program. The I-95 highway...

Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...

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...

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...

Does Landfill Leachate Make Clay Liners More Permeable?
Most environmental regulations require that clay liners exhibit permeabilities less than 1 x 10/u-⁷ cm/sec. While permeability is typically determined...

Can Clay Liners Prevent Migration of Toxic Leachate
According to recent research, low permeability clay barriers, used by landfill operators to contain hazardous wastes, can be rendered highly permeable by certain aggressive chemicals including...

New Uses For Soil-Cement
Since 1961, the use of soil-cement in energy and water resource projects has increased from 51,000 yd� to over 9,100,000 yd�. Its primary applications are erosion protection and seepage...

Teton Dam Failure
In June 1976, Teton Dam in Idaho failed. It was an earthfill dam 305 ft high. It failed by piping through the impermeable core of the dam. Among factors believed contributing to failure:...
