Measurements to Calibrate Suspended Sediment Model for Adsorbed Contaminant Transport Study of North Fork Holston River, Virginia
A daily suspended sediment (SS) and mercury transport model was developed for a 25-mile reach of the North Fork Holston River below Saltville, Virginia. Daily streamflow measurements;...
Sedimentation Aspects of Floodplain Management
This paper presents sedimentation aspects of a recent disastrous flood that occurred during September 10-12 1990 in the Han River basin, a central part of the Korean peninsula. The flood...
Hydraulic Roughness and Sediment Yield in Wheel Ruts on Forest Roads
Clear water flow and sediment yield from simulated wheel ruts in a forest road were measured at five different sites in the Northern Rocky Mountains. These measurements provided information...
An Engineering Analysis of Sedimentation in Tidal Inlets
The engineering comparative analysis of deposition and scour of noncohesive sediments in the neighborhood of bridges over tidal inlets is a unique problem which does not lend itself conveniently...
Fluvial Recharge of Sand Mining Pit
Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining...

Hypolimnetic Aeration in Three Swiss Lakes
Eutrophication is quite common in low altitude Swiss lakes. Government agencies have set up phosphorus and oxygen limits for streams and lakes. Aeration equipment has been in use for up...
A Decade of Recovery
The Outstanding Civil Engineering Achievement Award for 1991 went not to a single project, but to an entire decade's effort by the Portland (Ore.) District of the U.S. Army...
Engineering Tactics on Lifelines Safety Against Earthquakes
Effects of sediment-filled valley on seismic ground motions have become of major interest in earthquake engineering throughout this decade. This paper presents interesting phenomena of...
Case History of the Point Roberts Marina
This paper presents a fifteen year history of the design performance of the Point Roberts Marina. The 1,000 berth small craft harbor is located on the Strait of Georgia, immediately north...
Design Experience Gained Through Physical Modeling of Small-Craft Harbors
A research work unit has been initiated to determine the state-of-knowledge of small boat harbor design. Existing design criteria for small-craft harbor design is based primarily on 'rule-of-thumb'...
Predicting Sedimentation in Shallow Draft Coastal Ports
The U.S. Army Engineer Waterways Experiment Station is conducting a study to develop and improve design guidance for shallow draft coastal ports. As part of this effort and to fill gaps...
A Case Study of Propeller-Induced Currents and Sediment Transport in a Small Harbor
The operation of vessels in marinas and small harbors can provide important driving forces affecting ambient circulation patterns and current speeds near the bottom. The case study on...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
Rethinking Flood Control Channel Design
Until recently, the standard method of flood control was channelization�converting a natural stream to a uniform channel cross section. But this single objective approach is coming under...
Nagra Performance Assessment of Radioactive Waste Disposal in Crystalline and Sedimentaly Host Rocks
Nagra has evaluated disposal of vitrified HLW in both the crystalline basement of Northern Switzerland and in overlying argillaceous sedimentary formations. Although indicating that both...
Diffusion Coefficients and Hydraulic Conductivity in Unsaturated Hanford Soils and Sediments
Two groundwater transport parameters of some Hanford formation materials, the hydraulic conductivity and the diffusion coefficient, were measured to aid in predicting contaminant migration....
Uranium-Series Dating of Secondary Carbonates Near Yucca Mountain, Nevada: Applications to Tectonic, Paleoclimatic, and Paleohydrologic Problems
Near-surface accumulations of secondary carbonates are common in the soils and sediments of the Yucca Mountain area. These carbonates contain small amounts of uranium that allow dating...
Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair a problem of cattails growing in the low flow portion...
Sediment Management Challenges of the Red River Waterway Project
The Red River Waterway project consists of channel stabilization and construction of navigation locks and dams to provide a 9 foot minimum depth for a distance of approximately 236 miles,...
