Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
Simulation of Marsh Growth Under Rising Sea Levels
A method for computation of the rise of a marsh surface is presented that includes the effects of tidal and sea level variations, aggregation and deposition of cohesive suspended sediments,...
Modeling Boundary Layer Flow in Stormwater Detention Basins
An iterative procedure involving an implicit finite difference numerical scheme was implemented on an IBM personal computer for solving steady, uniform and nonuniform boundary layer flow...
Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...
Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....
Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....
The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...
Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...
Reliability Analysis of Water System Capacity
The paper presents, by means of an application, a few promising analytical methods for estimating bulk water system capacity reliability. In particular, this paper examines the applicability...
Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....
Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...
SEDIMOT II Application to a Large Coastal Watershed
SEDIMOT II was applied to Barker Reservoir watershed in Houston, Texas, in order to simulate sedimentation in the drainage area and the relative effectiveness of sediment control strategies....
Effect of Tall Vegetation on Erosion and Sedimentation: A Microcomputer Package
A model was developed to predict the effect of standing vegetation on sediment yield. The model is based on the relationship between local scour around standing vegetation and the role...
Coagulation in Natural Waters
The hydrodynamics and chemistry of particle-particle interactions can control the transport of particles and of particle-reactive pollutants. In lakes, particle deposition is accomplished...
Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...
Economics of Hydrothermal Power Development
The overall performance of a hydrothermal power plant with pumped storage is more cost effective than its competitive counterparts such as oil and gas turbine-generators. The operation...
Seasonal Hydrothermal Operating Plans
An interactive computer model is presented which provides graphical displays of alternative generation patterns for an integrated hydroelectric and thermal system. The method for analyzing...
Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...
