Major Results of Gravity and Magnetic Studies at Yucca Mountain, Nevada
About 4,000 gravity stations have been obtained at Yucca Mountain and vicinity since the beginning of radioactive-waste studies there in 1978. These data have been integrated with data...

Finite Element Approximation to Heat Transfer Through Construction Glass Blocks
The purpose of this study is to investigate the heat transfer through combined solid and fluid media, taking into account the interaction between the solid and the fluid. The main example...

A Contact Problem Modeling the Squeeze-Film Mode of Synovial Joint Lubrication
A contact problem modeling synovial joint lubrication under squeeze-film conditions is studied. In this model, the thin synovial fluid layer is incompressible and linearly viscous, and...

Spherical Shells with Nonuniform Rigidity
An iterative finite difference technique is presented in this paper for the analysis of axisymmetric spherical shells with variable wall thickness. The proposed method of solution is based...

Experiments on Stratified Flows: A Comparison with Theory
Stratified flows caused by salt wedges in estuaries, fjord flows and power station cooling waters represent very complicated flow situations with regard to their stability and rates of...

Standing Wave Measurements of Bedload Thickness: Feasibility in an Air System with Model Sediment
A novel technique would yield information about bedload thickness from measurements of a standing wave pattern produced by a sound source insonifying the bottom at normal incidence. The...

Influence of Hydrodynamics on Biofilm Accumulation
The influence of hydrodynamics on biofilm thickness was investigated under laminar and turbulent flow conditions. The maximum biofilm thickness was found within the transition region between...

Environmental Requirements of Lysimeters
Some of the more common environmental problems affecting measurement of evapotranspiration (Et) with lysimeters are discussed, including deviation...

Access Tube Characteristics and Neutron Meter Calibration
Neutron meter calibration was found to be influenced by material type, thickness and size of access tube. Meter counts were decreased by an average of 15% for a 20% increase in tube diameter...

Unsteady Flow of Bingham Viscoplastic Material in an Open Channel
An analytic solution for transient flow of a Bingham viscoplastic material in an open channel is presented. The solution for the response to a time-varying pressure gradient predicts shear...

An Experimental Study of Oil Spreading in Ice Covered Waters
In this paper the experimental procedure and some preliminary observations from a new series of experiments on the mechanism of oil spreading under fragmented ice are presented. Laboratory...

Riprap Stability in Channel Bends
A systematic test series is underway in a large test channel to define the stability of riprap on the outer bank of channel bends. A 'practical equilibrium' concept...

Design of Steel Tunnel Liners
The paper presents a detailed development of the fundamental equations for internal pressure design, considering an elastic interaction between the steel liner and the surrounding rock...

Guidelines for Design and Construction of Pozzolanic Stabilized Base Course Mixtures
The American Coal Ash Association (ACAA) has developed a manual of recommended practice which contains guidelines for the design and construction of pozzolanic stabilized base course mixtures...

Epoxy Update
Epoxy-coated reinforcing steel protects against corrosion if it is used correctly. Several construction practices, such as prescribing the limits on permissible coating damage due to shipping...

Gradation and Layer Thickness Effects on Riprap
Since riprap has become a costly and in some areas, scarce commodity, proper design maximizing the level of protection with a minimum rock size and layer thickness is an important goal....

Settlement of Light Buildings on Loose Sand
This paper reviews several cases of settlement of lightly loaded structures supported on granular soils. The concept of settlement ratio is presented. Measurements indicate that the settlement...

Concrete Block Paving for Marine Terminals
This paper describes the application of concrete block pavements to marine terminals. The Corps of Engineers flexible pavement design approach can be modified to provide a conservative...

In-Place Permeability Measurement of Slurry Trench Cutoff Walls
A suggested procedure for the in-place measurement of slurry trench cutoff wall permeability is presented. The H. Bouwer and Rice method, employing a single observation well and variable-head...

Design for Whipping Pipe Impact on Reinforced Concrete Panels
This paper describes determination of local and overall effects on reinforced concrete panels due to whipping pipe impact in postulated pipe break events. Local damage includes the prediction...
