Porous Pavement: Research, Development, and Demonstration
This paper discusses the U.S. Environmental Protection Agency's porous pavement research program along with the economies, advantages, potential applications, and status and...

Activated Carbon: Sorption of DOC from Wastewater
Activated carbons were prepared from a lignocellulosic material (prune pits) by pyrolysis to 900°C, and then activation in CO2 at 900°C for activation...

Elastic and Particulate Media
Constitutive relations for soil are proposed which given rise to a diffusion-like equation for the normal stress component. This partial differential equation includes both particulate...

Deformations and Stresses in Finite Porous Medium
Deformations and stresses in a fluid saturated porous medium of finite width are analyzed. The porous medium is assumed to be a binary mixture consisting of a linear elastic fluid and...

Flow Under Weir on Scoured Bed
An approximate analysis for seepage flow under a weir, resting on isotropic porous medium of infinite depth, with a vertical sheet pile at the toe and a segmental circular scour, is obtained...

Consolidation of Anelastic Porous Media
The transient response of saturated anelastic porous media is analyzed. The porous skeleton is modeled as a piecewise linear time-independent solid, and the fluid is assumed to behave...

Mathematical Model of Shallow Water Flow over Porous Media
A conjunctive mathematical model for a surface-subsurface flow system is developed. The unsteady surface flow is explored by a set of one-dimensional dynamic wave equations for shallow...

Advantages of boundary integral equation methods (BIEM) for the analysis of two-dimensional flows through porous media are numerous. The data required and the number of unknowns are significantly...

Seepage From Freewater Above Impermeable Tailings
A proposed model for seepage discharge into a porous embankment from free water above impermeable tailings is described. It is assumed that the discharge is controlled by saturated seepage...

Adaptive Solution of Free Surface Problems

Response to Dynamic Surface Pressure Distributions
This paper uses Biot's theory for poroelastic media to examine the response to dynamic surface pressure distribution of layered systems of fluid-filled soils or porous rock. Pressure distributions...

Damping of Gravity Waves Over Porous Bed
The damping of gravity waves over the contaminated free surface of a viscous layer of fluid that is bounded below by a porous bed is investigated. It is assumed that the bed is saturated...

Singularities in Darcy Flow Through Porous Media
Several types of singularities which threaten the integrity of numerical solutions occur in potential flow problems. The singularity at the tip of a cutoff wall is strong and cannot be...

Flow of Dilute Polymers Through Porous Media
The flow of dilute polymer solutions through porous media is investigated experimentally. Large increases in flow resistance are noted, considerably higher than would be expected from...

Self-Consistent Techniques for Heterogeneous Media
The basis for the estimates is given in the form of an auxiliary solution characterizing the behavior of a single embedded site. Both classical self-consistent methodologies (SCM) and...
