Sediment Discharge Computation Procedures

Journal of the Hydraulics Division, 1972
An analysis is made of some of the recent and more accepted sediment transport concepts as related to transport rates in flow systems. The analysis covers bed, suspended, and total load discharge computation procedures with descriptions of mathematical modeling techniques where applicable.

Sediment Discharge Computation Using Point‐Sampled Suspended‐Sediment Data

Journal of Hydraulic Engineering, 1991
A procedure, TSD (total sediment discharge), for computing total sediment discharge using point‐sampled suspended‐sediment data is presented and tested with field data. TSD was found to provide total sediment discharge estimates that are similar in magnitude to both turbulence flume measurements of total sediment discharge and modified Einstein ...

Contractor Penalized for Discharging Sediment

Journal AWWA, 1993
As the site‐grading contractor for a project in Alabama, Wright Brothers Construction Company cut and filled a portion of Red Mountain to create a level 60‐acre site for development. The contract said Wright was responsible for erosion and pollution control.

A sediment history of sellafiel discharges

Journal of Environmental Radioactivity, 1990
Abstract A suite of artificial radionuclides, discharged from the BNFL Sellafield works into the Irish Sea, has been measured in sediment cores taken from a nearby disused and undisturbed dock basin (Senhouse Dock, Maryport). This has provided a comprehensive record of Sellafield discharges from the early 1960s, including radionuclides for which ...

Sediment Discharge Model for Small Watersheds

Transactions of the ASAE, 1989
ABSTRACT The sediment discharge component of a watershed simulation model called RUNOFF is presented. The model component uses a runoff simulation component and simulates space and time distributed soil erosion, sediment transport and sediment deposition and computes sediment discharges in a small watershed resulting from a single rainfall event.

Improving sediment discharge prediction for overbank flows

Water Management, 2005
The Ackers and White (Journal of Hydraulic Division, ASCE, 1973, 99, No. NY11, 2041–2060) and the Yang (Journal of Hydrology, 1979, 40, 123–138) sediment transport formulae, both based on the stream power theory, were applied to experimental data for sediment transport during overbank flow obtained from the large-scale UK Flood Channel Facility and ...

Sediment discharge prediction in meandering compound channels

Journal of Hydraulic Research, 2006
Three sediment transport formulae have been applied to experimental data for sediment transport during inbank and overbank flow in meandering compound channels. The experimental tests were undertaken in the large-scale UK Flood Channel Facility and the small-scale Ulster Channel.

Total sediment discharge sampling over sills

Water Resources Research, 1974
Easily installed wooden sills permit collection of bed load sediment normally missed in the ‘unsampled zone.’ Sills also (1) provide a rigid unchanging control at which to sample, (2) reduce the chance of sample bias from sediment stirred up by the wader, and (3) permit control of the sampling interval because the sample points can be marked directly ...

Model Calibration for Sediment Pond Discharge

World Environmental and Water Resources Congress 2007, 2007
The author's two-dimensional model for unsteady sediment discharge at a pond outlet was developed using the finite element method. The model simulates depth-averaged flow velocity in the pond and the depth-averaged suspended sediment moving from the pond inlet to the outlet.

Hydro-Induction Sediment Discharge Technique for Preventing Sedimentation in Hydropower Dams

Critical Transitions in Water and Environmental Resources Management, 2004
Hydro-induction sediment discharge technique (HSDT) aims to prevent reservoir sedimentation by withdrawing the discharge water from the reservoir bottom to suck up and discharge sediments, and by inducing vertical vortexes and undercurrents in the reservoir bay to keep sediments agitated and moving.
