Becker Test Results from Gravel Liquefaction Sites
A Practical Perspective on Liquefaction of Gravels
Large-Stone Aggregate-Modified Asphalt Mixes
Uncertainty in Economic Evaluation of Upgrading Gravel Surface Roads
Many highway links in the world are still gravel surfaced. As traffic volumes increase, the demand for upgrading these surface also increases. The challenge to highway infrastructure management...
Geologic Assessments and Characterization of Marine Sand Resources?Gulf of Mexico Region
The U.S. Geological Survey conducts geologic surveys and research in marine areas of the United States and its territories and possessions. An objective in some of the investigations is...
Artificial Gravel Beaches in the Coastal Protection
Gravel beaches on the Caucasian Black Sea coast are intensively eroded mainly because of man meddling in natural course of coastal processes (sediment withdrawal from beaches and river...
Specific Features of Shoreline Development in Sochi Region and Engineering Methods of Coast Protection
A coast segment from Tuapse City to the Psou River, 113 km long, is extended in this paper. Geological description of the coast has been made, and approximate values of the abrasion rate...
Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...
Sediment Budgets in Gravel Bed Streams
A sediment budget/mass balance technique is presented for use in assessment of sediment transport by river reach in gravel bed streams. Selection of appropriate gravel bed transport equations,...
Design of Pre-excavated Scour Hole Below Flip Bucket Spillways
A number of tests were performed on a model-scale flip bucket spillway with a gravel-bed plunge pool in order to develop equations to describe the geometry of the scour hole created by...
Video Analysis of Gravel Saltation
Experimental results concerning saltation characteristics of gravel particles in a movable bed channel are analyzed by using video imaging techniques. Ensemble averaged values of saltation...
The Flushing Flow Problem on the Trinity River, CA
Flushing flows are high flow releases designed to remove fine sediment accumulated in river gravels downstream of reservoirs. These releases must be designed to maximize transport of sand-sized...
An Application of Nonhomogeneous Poisson Process in Sediment Infiltration Into Gravel Bed
The compound homogenous Poisson process (CNHPP) model (Shen & Todorovic, 1971 ) is found applicable in sediment infiltration into gravel bed due to the unsteady and nonuniform...
Prediction of Gravel Transport Using Parker's Algorithm
This paper demonstrates that sediment discharge in gravel streams can be reasonably estimated by calibrating the Parker and Klingeman procedure. This paper also identifies the need for...
Selecting Sediment Transport Equation for Scour Simulation at Bridge Crossing
Gravel transport formulas were tested in order to select a formula for simulating stream channel changes of Stony Creek in northern California. At a stream reach undergoing scour, the...
Harry Seed, Liquefaction & the Gravel Drain
The late Professor Seed of the University of California at Berkeley established criteria for gravel drain design in a 1977 ASCE paper. Without historical proof for its viability in a real...

U.S. Experience With Armor-Stone Quality and Performance
In the past 30 years problems with deterioration and cracking of armor stone in the United States have been concentrated in northern regions, particularly around the Great Lakes. The explanation...
