Saturation Effects on Initial Soil Liquefaction
Soil liquefaction has become an important consideration in the design of structures in seismically active regions. Many researchers have in the past attempted to determine the liquefaction...

Location of Free Surface in Porous Media
The boundary integral equation method (BIEM) is applied to the problem of locating the free surface in both steady and unsteady flow through porous media. The method is numerical in its...

Characterization of Coarse Porous Media
A methodology is presented to characterize shape factor and surface area of coarse filter media. For several regular geometrical solids the variation of shape factor with a dimensionless...

Nonlinear Adsorption in Layered Porous Media Flow
Dispersion and adsorption of solute in multilayer saturated porous media with constant specific discharge are examined in the present work. Differential equations are formulated for describing...

Aeration of Hydro Releases at Ft. Patrick Henry Dam
A method has been developed for increasing dissolved oxygen concentrations in the turbine releases from hydroelectric power plants. A systematic procedure was used for evaluating promising...

Viscoelasticity of Solidifying Porous MaterialĀ°Concrete
The form of the age effect on linear creep and elasticity is established by treating the hydrating cement paste as a variable composite in which the volume fraction of solid grows while...

Non-Darcy Flow and its Implications to Seepage Problems
Analytical solutions for the problems of drainage spacing in a ditch drainage system and steady-state seepagee through confined aquifer of variable thickness incorporating Izbash's nonlinear...

Radial Dispersion Through Adsorbing Media
The convective-dispersion equation for the transport of a radioactive tracer through an adsorbing porous medium is solved in the cylindrical polar system of coordinates by the Galerkin...

Transient Dispersion in Uniform Media Flow
Analytical solutions are developed for the transient dispersion from a finite line source or a rectangular plane source in saturated steady uniform porous media flow. The sources are oriented...

Porous Friction Course Solves Airport Hydroplaning Problem
Several hydroplaning incidents had occurred at the Greensboro-High Point-Winston Salem Regional Airport, N.C. Hydroplaning occurs when hydrostatic pressure builds up in the field of surface...

Consolidation with Internal Pressure Generation
Cyclic loading on saturated soils usually caused both a rise and fall in the excess pore pressure and a net increase of the pore pressure with each cycle. When no drainage occurs, the...

Diffusion of Water under Subfreezing Temperature
Several workers have investigated the diffusion of water in soil under a temperature gradient above the freezing point. However, only limited studies seem to have been carried out under...

Analysis of Swelling-Soil Column Infiltration Test
The most common procedure for measuring the diffusivity of unsaturated soils is the infiltration test. This note considers the use of the soil column infiltration test on expansive clay...

Seepage from Trapezoidal Canal in Anisotropic Soil
An analytical solution is found for the problem of seepage flow from an unlined trapezoidal canal, taking into account the general anisotropic behavior of the porous medium. Since a canal...

Seepage through Opening in Cutoff Wall Under Weir
A solution to the problem of seepage through an opening in a cutoff wall under an impervious structure lying on the ground level is presented with the use of the conformal transformation...
