A Continuum Mechanics Approach to Loose-Bed Motion
A mathematical model is presented for simulation of loose-bed motion. The physical system is separated into two regions, a bottom region and an upper region. The bottom region is representative...

Integral Length Scale in Sediment-Suspending Flow
The Clauser integral length scale is an adequate scaling parameter for velocity defect profiles in clearwater and sediment-suspending flows in open channels. Velocity defect profiles plotted...

Near Bed Sediment Concentration as Influenced by Turbulence
Suspended sediment concentration profiles are developed based on the conservation of mass and conservation of momentum equations of sediment laden flows. The resulting concentration profile...

Energy Relations for Suspended Sediment Transport
One of the main difficulties in predicting transport rates of suspended sediment on the basis of the Rouse-expression for relative sediment concentrations, is the lack of any reliable...

The Structure of Intermittent Sand Suspension Events Under Mild Wave Conditions
Nearshore sedimentation processes are being actively investigated through a series of research projects at the University of Miami. Quantitative measurements of waves, currents, and suspended...

Highly Concentrated Sediment Loads of the Yellow River
A set of high concentration data for the Yellow River in China is examined and compared with low concentration data and laboratory experimental results....

Sediment Transport in Hyperconcentrated Flows in Sand-Bed Streams
This study advances the understanding of sediment transport of bed material discharge in sand bed streams through application of recently developed theoretical concepts related to the...

The Relationship of Milligrams Per Liter to Parts Per Million
Derivations of the relationships between mg/l and ppm are presented. Although forms of these relationships can be found in scattered references, the author's intent is to...

Prediction of Time Development of Local Scour
The prediction of the time development of local scour is commonly solved by means of model tests. A brief description of the time-scale and the relation between the time and the scour...

Suspended Sediment Regression Model on Mud Coasts
Two statistical models of the concentration of suspended sediment on mud coasts have been developed by using the stepwise regression method. The statistical analysis in this paper is based...

Suspended Sediment Model of Offshore Tin Mining
The three dimensional dispersion equation is integrated vertically to use in describing the suspension of silt from offshore tin mining. The resulting two dimensional equation includes...

Two Dimensional Nonequilibrium Transport of Nonuniform Sediment
Mathematical models based on diffusion and/or diffusion convection equations have been widely applied to study sediment transport in suspension. Some of the studies were reported by C.C....

On the Coexistence of Bedload and Suspended Transport for a Uniform Grainsize Material
A sensitivity analysis and an experimental verification have been made to assess the validity of the equations that describe the sediment transport in non-equilibrium conditions, when...

Sediment Transport Rate for Non-uniform Sand
Based on the equations of bedload transport by authors, the functional relation of total sediment transport capacity of flow has been found. The modifying coefficient due to non-uniformity...

Daily Suspended Sediment Model for Water Resources Management
A daily model of streamflow and suspended sediment (SS) concentrations has been developed to analyze daily suspended sediment records from tributary basins. The model provides a method...

Total Sediment Discharge Measurement
A procedure for measuring total sediment discharge using point-source suspended-sediment data was developed. The procedure, Total Sediment Discharge (TSD), was compared to field and modified...

Estimation of Unsampled Sediment Discharge
A procedure is developed to estimate the total bed material load without using the size distribution of suspended load. Because of the uncertainties involved in the calculation of the...

Convective Sedimentation from a Stable Turbid Layer
A set of experiments was conducted to test T Green's criterion for the existence of double-diffusive convective motions at an originally sharp, horizontal interface separating...

Measuring Resuspension of Sediment by Barge Tows
An earlier effort to measure resuspension of sediment relied on U.S. standard depth-integrating sediment samplers. In designing a new effort to collect field data on resuspension, the...

Intrusion of Turbid Water into a Two-Layer Stratified Environment
The horizontal intrusion of a turbid water with some intermediate density spreading on the interface of a two-layered homogeneous body of water is investigated. The study is directed towards...
