Influence of a Sand Layer on Headcut Advance
The presence of an erodible material layer in the soil profile has been observed to influence headcut movement in earth emergency spillways. Large-scale flume tests were conducted to examine...

West Columbus, OH LPP Gate Closure Analysis - A Study of the Requirements for Multiple Closures
Providing flood protection by levees and/or floodwalls often requires the use of temporary closures, in lieu of the more expensive relocation of highways and railroads, in order to maintain...

Hydraulics and Sediment Transport Processes in a Pool-Riffle Rocky Mountain Stream
Sediment transport processes related to varying channel-bed morphology were investigated from April to November, 1993 along a 1 km pool-riffle and step-pool reach of North Saint Vrain...

Analysis of Selected Prototype Wave and Runup Data
An investigation of wave runup using video camera technology at Duck, N.C. is discussed. Results are provided from a subset of the runup experiment and wave runup level probability density...

Analysis of Sand Movement on Noto Coast by Geochemical Method
The analysis of sand samples by X - ray fluorescent spectroscopy (abbreviated by XRF) gives the ratio of the geochemical elements to construct the sand samples. This shows the geochemical...

Sheet Flow Resistance of Asphaltic Pavements
A statistical study has been conducted by the authors using 400 points of experimental data taken in the 1970's at Texas A&M for sheet flow runoff during artificial rainfall on...

Sandbar Formation in Side-Diversion Channels
Prediction of sandbar formation in side-diversion channels is desirable in a wide range of river engineering problems. However, the mechanism by which they form is still not well understood...

Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...

Numerical Analysis of High Velocity Flow with Zero-Depth Line and Oblique Shock Wave in Steep Open-Channels
This paper deals with the numerical analysis of 2D steady high velocity flows with the zero - depth line and the oblique shock wave in steep open channels by means of the method of characteristics....

Considerations in 2-D Modeling of Hydraulically Steep Flow
Simplifications in the equations used to describe shallow water flow lead to some difficulties in modeling supercritical flow. The hydrostatic assumption produces two significant differences...

Ocean Wave Measurement and Analysis
This proceedings, Ocean Wave Measurement and Analysis, consists of papers presented at the Second International Symposium on Ocean Wave Measurement...

Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...

Coastal Dynamics `94
During the past decade, numerical models of coastal dynamics have provided far more information than could be validated with field and laboratory measurements. Lack of data has restricted...

Reconstruction of the West Breakwater at Port Sines, Portugal
This volume, Reconstruction of the West Breakwater at Port Sines, Portugal, is a collection of papers presented at a seminar held at Sines,...

Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...

Estimation of Near-Regional Seismic Ground Motion from Underground Nuclear Explosion Tests
A problem unique to the location of a nuclear waste repository adjacent to the Nevada Test Site is the assessment of seismic ground motion from potential underground nuclear explosion...

Seismic Considerations in Sealing a Potential High-Level Radioactive Waste Repository
The potential repository system is intended to isolate high-level radioactive waste at Yucca Mountain according to the performance objective - 10 CFR 60.112. One subsystem that may contribute...

Stress Wave Loading of a Tunnel: A Benchmark Study
Five different finite element or discrete element computer codes were used to solve a sequence of problems leading to the problem of stress-wave loading of a circular tunnel in a jointed...

Three-Dimensional Simulations of Ground Motions in Sedimentary Basins
This report describes work being done at the U.S. Geological Survey on 3-D simulations of earthquake ground motions in sedimentary basins. The ultimate goal of this research is to predict...

Nonlinear Dynamic Analysis of Single Point Moored Buoy Under Wave and Current Loadings
In this study, a single point moored spherical buoy under wave and current loadings is analyzed in the time domain considering time memory effects. Geometric nonlinearity of the mooring...
