Flow and Transport of Nonaqueous Phase Liquids in Groundwater Systems
Nonaqueous phase liquids (NAPLs) are present at numerous hazardous waste sites and are suspected to exist at many more. Due to the numerous variables influencing NAPL transport and fate...

Mass Transport in Mud Layer Induced by Wave Action
This paper analyzes the mass transport velocity in a two layers system produced by wave action. In a previous paper, Piedra Cueva (1933), a theory for linear water waves propagating in...

Assessment and Prediction of Debris-flow Hazards
Study of debris-flow geomorphology and initiation mechanism has led to better understanding of debris-flow processes. This paper reviews how this understanding is used in current techniques...

Oxygenation Experiments in the Wave Breaking Zone
Experiments on oxygenation due to waves breaking on a uniformly sloping beach were carried out at the laboratory of Harbor Works, National Technical University of Athens. The influence...

Force Transfer in Composite Columns
The force transfer from steel to concrete without mechanical transfer devices in composite columns at points of load introduction is studied. A mechanism of force transfer and the factors...

Perimeter Load Transfer in Drilled Shafts in the Eagle Ford Formation
Results of six full-scale compression loading tests at four sites in the Dallas area are considered. Compressive strengths (qc) of the rock varied...

The Financing Fray
Interview with two executives of the U.S. firm Morrison-Knudsen: Donn Smith, senior vice president of project finance at M-K's International Group, and Richard White, vice...

Problems With Armor-Stone Quality on Lakes Michigan, Huron, and Erie
The instances of deterioration of armor stone at coastal structures on the Great Lakes result from numerous distinct causes, both intrinsic and extrinsic. However, the proof of specific...

The Durability of Rubble Mound Armour in Service ? A Case Study
Over the past decade, the ongoing monitoring of Gold Coast rubble mound structures in service has demonstrated a serious loss of durability over a period of time in the rock units after...

The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...

Frictional Aspect of Rocking-Sliding of a Rigid Block with Surface Impact
During the very short time of impact between a rigid rectangular block and a rigid foundation, the interface pressure distribution varies with time in a complicated manner. Due to this...

Joint Network Modeling and Scale Effects in Rock
Joint networks play a vital role in the mechanical and hydraulic behavior of rock masses. A realistic representation of joint geometry in rock masses and correct understanding of the mechanical...

Steady-State Nonlinear Heat Transfer in Multilayered Composite Panels
A two-dimensional computational model is developed for the nonlinear heat transfer in multilayered composite panels. The model is based on a first-order thermal lamination theory with...

Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...

Application of a Boundary Fitted Coordinate Mass Transport Model
A three-dimensional, boundary fitted coordinate, finite difference, mass transport model was applied to the Providence River in Upper Narragansett Bay, Rhode Island. The governing advection-diffusion...

Approximation of Convective Processes by Cyclic AOI Methods
Convective or advective processes play a role in many models for civil engineering applications. For example in transport equations, in hydrodynamic equations or wave energy equations....

Advancing Anchorage Technology
An overview of earth anchorage technology, with emphasis on current U.S. corrosion protection practice as compared to that used in Europe. Comments from U.S. practitioners involved in...

Norway's Olympic Cavern
A mountainous task had been undertaken by Norwegian firms in constructing the world's largest in-mountain colosseum for the 1994 Winter Olympic Games in Norway. The Norwegian...

MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...

Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...
