Intermediate-Scale Experiments in Solute Transport at Los Alamos: Role and Experiences

Parking Lot Drainage Design: Gainesville, Florida
The construction of a 10-acre (4. 05 ha) parking facility (1,000-car capacity) at the University of Florida during 1984 presented the potential for increasing downstream flooding and for...

Contaminant Transport from an Array of Sources
The authors show analytic solutions to the problem of contaminant dispersion from an array of point sources in a waste disposal site. These solutions are for waste sources in a fluid-saturated...

Water Table and Salinity Movement in a Silty Clay Soil
The movement of the water table and profile salinity in a shallow drained soil in permanent pasture overlying an artesian aquifer was observed. Soil samples were taken before and after...

Large Mat Foundation Analysis on Expansive Soil
This paper describes a comparison of predicted and observed performance of mat foundations on stiff expansive soil. Foundation performance was predicted using a new computer program BOSEF...

Dispersion in an Unbounded Stratified Porous Medium

Transport in a Porous Medium with Randomly Varying Parameters

Field Permeability Test for Earthen Liners
A sealed double-ring infiltrometer (SDRI) was developed for in-situ measurements of the hydraulic conductivity of earthen liners and covers. The characteristic of the SDRI that distinguishes...

Permeability, and the Field Pumping Test
Methods of estimating in situ permeability of soils are discussed including laboratory tests, borehole tests and field pumping tests, with emphasis on the latter. Techniques for designing...

In Situ Measurement of Permeability in Soft Clays
As part of an extensive field programme, the magnitude of errors due to clay remoulding and filter clogging in tests performed in common piezometers is evidenced. Comparisons between variable...

A Field Study of Water Movement Through Clay Liners
A monitoring system has been designed for the field verification of a numerical model of water movement through the cover clay liner of hazardous waste landfills. The most unique aspect...

Effects of Artificial Recharge on Ground-Water Quality, Long Island, New York
Artificial-recharge experiments were conducted at East Meadow in central Nassau County, Long Island, N. Y. , from October 1982 through January 1984, to evaluate the degree of ground-water...

Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...

Endangerment Assessment in a Multilayered Aquifer Using a Microcomputer Based Transport Model
An endangerment assessment describes the types and degrees of potential hazards to public health, welfare, or the environment that may result from the release of hazardous substances into...

Leakage from Pressure Tunnels and Shafts
Several issues related to leakage from unlined pressure tunnels and shafts are reviewed and discussed. They include confinement, or cover requirements relative to hydraulic jacking of...

Thermal Monitoring of Leakage Through Dams
The technique involves very accurate temperature measurement at shallow depth below the reach of the surface diurnal cycle. Temperatures respond to subsurface water movement (with advective...

Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...

Seepage in the Unsaturated Zone: A Review
This paper briefly reviews the procedures whereby the seepage rate, depth of penetration of nonreactive pollutants, and the depth of the wetting front can be calculated when the assumption...

Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...

Grout Penetrability
The ability of a grout to penetrate a formation is always a selection requirement for projects in which fracturing is undesirable. The major grout properties affecting penetrability are...
