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...

Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...

Evaluation of the Potential for Release of Residual Coal Tar by Flood Scour at a Superfund Site
To address the potential for release of residual coal tar by flood scour, stream cross-sections, stream discharge and sediment grain size data were collected during the Remedial Investigation...

An Expert Advisor for Selective Withdrawal Operations
A rule-based computational advisor that aids in the selection of selective withdrawal operations for project release temperature maintenance is discussed. This advisor couples a one-dimensional...

Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. 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....

Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...

The Equivalence of Path and Node Methods for Water Distribution Network Analysis
This paper deals with the equivalence between commonly employed methods, path and node adjustment methods, for analyzing water distribution networks. The basic equations for steady-state...

Coronarization of the Autonomous Water pump
The conventional hydraulic pressure multiplier has been successfully used by Belgian technician Robert Houman (1986) to provide a dependable source of water supply to the NATO-base at...

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...

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...

Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...

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...
