Modification to John H. Overton Lock and Dam
The Red River Waterway Project, Mississippi River to Shreveport, Louisiana, will consist of a navigation channel 9 feet (2.7m) deep by 200 feet (61.0m) wide, 5 locks and dams providing...
The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...
Comparison of Correction Factor for Dispersion Coefficient Based on Entropy and Logarithmic Velocity Profiles
Recently, new velocity distribution equations have been developed by Chiu (1987, 1989) through the use of maximum entropy principle. A comparison will be made of the correction factor...
On the Problem of Sediment Deposition in Large Reservoirs
Sediment deposition and its accumulation in a large reservoir depends on the inflow and reservoir storage content, respectively. This fact is used to model the cumulative deposition of...
Application of the Ackers-White Procedure for Transport by Size Fractions and Testing in HEC-6
Modification of the Ackers-White method for the calculation of sediment transport by size fractions has led to a procedure which not only permits such calculations, but also increases...
Numerical Modeling of a Trench Fill and Scour
The sediment fill and scour in a dredged trench was numerically simulated by the nodal-collocation finite element method and an explicit scheme. The one-dimensional unsteady sediment-laden...
Urban 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 an all too familiar problem of cattails growing in the...
Equivalence Between Regular and Irregular Waves in Movable-Bed Models
Laboratory experiments were conducted to evaluate various irregular wave parameters to determine which provides the best match for the regular wave parameter used to develop design guidance....
Data Acquisition for Determining the Physical Impacts of Navigation
Research is being conducted to determine the physical effects of navigation on the Upper Mississippi River System (UMRS). Extensive field data on various aspects of physical effects of...
Computation of Sediment Transport Resulting From Snowmelt and Rainfall in a Sierra Nevada Watershed
Erosion within a watershed can cause extensive damage to the land and adjacent properties. It is a common problem throughout the United States, and has become severe in many areas of the...
Performance Test of Some Selected Sediment Transport Formulas
Performance of some selected sediment transport formulas was tested using a parameter-sensitivity analysis and a series of numerical experiments with an imaginary channel data. Selection...
River Sediment Discharge Study?San Diego Region
Procedures and general results are presented of a recent study performed to estimate the average annual sediment delivery (sand sizes and larger) from sources discharging to the southern...
Hydraulic Modeling of Boating Hazards and Sedimentation?Union Avenue Dam, Denver Colorado
Hydraulic jump type energy dissipators are a hazard to recreational boaters. Many white water boaters have been trapped in 'reverse roller' hydraulic jumps. Numerous...
The Study and Practice of the River Regime Planning and Sediment Management in Gezhouba Project of the Yangtze
Based on the Practice of Gezhouba Project, the first water control project on the mainstem of the Yangtze and the largest hydroproject in China, this paper lays emphasis on importance...
Cumulative Impacts Analysis on a Midwest Fluvial System
The US Army Corps of Engineers recently completed an analysis of the cumulative impacts of erosion control structures on the Platte River in Nebraska. This was done in response to concerns...
Sediment Yield and Accumulation in the Cache River
Sediment data collected in the Cache River basin of southern Illinois were used to calculate the sediment yield from tributary streams draining into a significant wetland area. Sediment...
Geomorphic and Sedimentologic Evaluation of a Proposed Flood Control Project, Truckee River, Reno, Nevada
Geomorphic observations, sediment data and shear stress analyses were integrated to evaluate the potential responses of the steep, coarse grained Truckee River to a proposed flood control...
Sediment Management with Submerged Vanes
Submerged vanes are small river training structures used for protection of streambanks against erosion and for amelioration of shoaling problems in navigation channels, at water intakes,...
Experimental Study on the Hydraulic Characteristic and Trapping Efficiency of a Vortex Tube Sediment Trap
In this paper, an expression of water extractor ratio of a vortex tube has been obtained according to the principle of energy conservation and transformation; based on the feature of sediment...
Corps of Engineers Sediment Management Program
The existing sediment management program includes sediment investigations of reservoir, river and levee projects; gathering and maintaining sediment load records; providing sediment investigation...
