# Limit Concentration of Suspended Sediment

*It is found from experiments that there is a limit on suspended sediment concentration. The limit concentration of uniform sediment varies with sediment diameter, and it is about 1000...*

Scour in Non-Cohesive Beds at Culvert Outlets

*An empirical relationship was developed to estimate the depth of scour in non-cohesive material at culvert outlets. The scour depth is expressed as a function of mean particle size 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...*

Stratification by Solid Particle Suspensions

Hydrodynamic Characteristics of Particles in Biological Fluidized Beds

Erosion Processes in Upland Areas

*After a soil particle is detached and entrained, it will be transported by the surface runoff. However, depending on the eroding and transport capacities of the surface runoff, some of...*

Deposition of Airborne Particles from Fractured Spent Fuel or High-Level Waste

*Preliminary equations are developed to predict the amount of deposition of airborne particles that may result from an accidental release in a hot cell. The fraction of these airborne particles...*

Derivation of a Stability Principle from the Shields Criterion

*The widely used specific energy equation, which defines the subcritical and supercritical states of the open channel flow, is a direct result of the integration of the Froude number corresponding...*

Towards a Distinct Treatment of Incipient Motion for Bed Forms of Low Regime

*The principle methods for estimating the incipient particle motion on developed bed forms in the lower regime are compared with each other. Usually only a part of the total wall shear...*

Laboratory Analysis of Hyperconcentrations

*The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses...*

Sediment Transport Due to Turbidity Currents

*The processes of sediment transport in a horizontal channel due to low-Reynolds-number turbidity currents are evaluated. A multiple-layer numerical model was developed to predict the flow...*

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...*

Areal Sampling Techniques

*Three areal methods, commonly used for sampling the coarser surface layer of gravel-bed streams, are examined. An idealized sediment deposit, that consists of cubic particles and accounts...*

Surface Water Particles: Coagulation and Sorption

*A size-dependent particle and particle-associated contaminant transport and fate model is presented. The unsteady, two-dimensional model couples the water column and bed and enables analysis...*

Radiation Hazards to Space Construction - The Energetic Particle Environments

*Many aspects of the space environment are recognized hazards for activities above the Earth's atmosphere. One of the most dramatic hazards is that posed by the diverse energetic...*

Acoustic Determination of Suspended Particle Size Spectra

Dispersion of Coal Particles at the Sea Floor

*Due to coal unloading, certain quantities of this material arrive at the sea floor, and may pollute the beaches. This study provides a theoretical analysis and numerical simulations of...*

Inactivation of Total Coliform Bacteria Associated with Particles by Ozonation

Modeling Cohesive Sediment-Pollutant Interaction in Surface Waters

*Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating two-dimensional...*

Cellular-Automata for Hydrodynamic Modeling

*A two-dimensional fluid continuum system can be modeled using a discrete field of particles that interact according to simple deterministic rules. The methodology is called Cellular Automata....*
