Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...

Model-Prototype Comparison of the Pressure Fluctuations in the Boundary Layer of a High-Head Tunnel Spillway

Applications of GSTARS Model
GSTARS is a Generalized Stream Tube model for Alluvial River Simulation. Depending on an engineer's need, GSTARS can be used as a fixed boundary as well as a movable boundary...

Rigid-Lid Flow Calculations with MacCormack's Method
R.W. MacCormack's Method is employed for the calculation of subcritical flow in shallow water. The flow is assumed to be incompressible with rigid boundaries above and below,...

Section Three—Geotechnical Thermal Analysis

Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...

Boundary Integral Equation Approach to Earthquake Induced Hydrodynamic Forces

Simulation of Sand Accumulation Around Fences

A 3 MHz Acoustic Sediment Profiling System

Random Wave Forces on Cylinder Near a Boundary

A Comparison of Tidal Sediment Boundary Layer Profiles with Theory
A number of theoretical derivations have been presented for predictions of the sediment concentration profile near or at the bottom of a column of surface water. Ultrasonic transceivers...

Computation of Supercritical Flow in Open Channels
The use of two explicit, shock-capturing, finite-difference schemes, Lax and MacCormack, for the solution of two-dimensional shallow-water equations in steady, supercritical flow is investigated....

Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...

Estimation of Mean Water Depth for Border Irrigation
The mean water depth for border irrigation is derived, using dam-break simple wave solution and boundary layer theory, as a function of inflow discharge, bottom slope, bottom roughness,...

Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Deepwater Sediment Concentration Profiling in HEBBLE using a One Megahertz Acoustic Backscatter System

Shoreline Development in Southern Lake Michigan
This abstract refers to the effect that record-high lake levels, shoreline erosion, and the decline of the steel industry are having on present and future plans for shoreline development...

Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....

Dynamic Soil-Structure Interaction by the Boundary Element Method: A Comparison Study
A comparison study of three Boundary Element Method approaches is attempted on the basis of a typical three-dimensional, dynamic soil-structure interaction problem. The vertical transient...
