Discrete Mechanics of Sediment Transport
Usually a granular medium is being represented by a continuous approximation in which the degrees of freedom of individual grains are averaged away in favor of a partial differential equation...
Erosion of Steep River Banks and Time Evolution Towards Equilibrium Channel Shape
A numerical analysis of the time evolution of straight river channels is presented. The bed and bank, material is taken to be coarse, non-cohesive and uniform in size. As a result of the...
Three-Dimensional Eulerian-Lagrangian Transport Model
An Eulerian-Lagrangian algorithm, based on operator-splitting techniques has been formulated for the three-dimensional advection-diffusion equation. This combines the advantage of a fixed...

An Experimental Model Using a Graphical User Interface
This paper describes a program named Plume which runs on a microcomputer. The intended function of the program is to enhance an investigator's understanding of the estuarine environment...
Modeling Three-Dimensional Circulation and Sediment Transport in Lakes and Estuaries
The transport of fine sediments due to currents and wind waves in estuaries and lakes have been studied by means of field experiments, laboratory experiments, and a comprehensive three-dimensional...
Passive Dispersive Transport Modelling: Comparison with Experimental Rhodamine Data in the Elbe Estuary, Germany
Aiming at modelling of the complex water mass, suspended matter and pollutant transport in a tidal estuary, the ability of simulating the transport of passive, conservative tracers is...
A PC Modelling System for the Simulation of Transport and Fate of Solutes and Suspended Substances
PARTICLE is a numerical computer model for the simulation of transport and fate of discharged, dissolved or suspended substances. The model is based upon the Lagrangian approach and calculates...
The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...
Modeling the Pathways of Nonconservative Substances in Estuaries
ELAmet is a model for nonconservative chemical transport which solves the advection/dispersion/transformation equation using a modification of Eulerian-Lagrangian methods. In this paper...
Modeling Transport and Fate of Micropollutants in Coastal Waters
In order to assess rate and risk of pollution of coastal waters, attention should be given to the input of pollutants, the transport of pollutants, the transfer of pollution between water...
Modeling Tidal and Wind Driven Circulation in Sarasota and Tampa Bay
As part of an effort to quantify the effects of hydrodynamics on water quality within Sarasota Bay, Tampa Bay and their adjoining waters, a field and modeling study of circulation and...
A Three-Dimensional Simulation of Buoyancy and Wind-Induced Circulation and Mixing in the New York Bight
A three-dimensional simulation of the circulation and mixing in the New York Bight has been conducted, forced by (i) wind stress for the year 1987 and monthly-mean heat fluxes at the sea...
Assessing
The New York Bight had been receiving waste disposals, dredged spoils and acid dumps for the past 30-40 years causing accumulation of trace metals such as Cu(II) in water and sediment....
Sensitivity of Flow and Salt Transport to Uncertainties at Open Boundaries: A 3-D Experience
Understanding the transport due to tidal and sub-tidal exchange processes enables many environmental issues in estuarine systems to be addressed. To achieve this goal, a reliable numerical...
Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...
Differential Motions in Sedimentary Valleys
The differential motions (strains), induced in sediment-filled valleys due to incident seismic waves, are investigated. The response of a two-dimensional model of an asymmetric wedge-shaped...
Prediction of Sedimentgraph from a Small Watershed in Poland in a Changing Environment
Estimates of sedimentgraphs and temporal distributions of sediment concentrations are essential for prediction of pollutant concentrations in streams and reservoirs. In such predictions,...
Linking GIS with Hydrologic Modeling
A GIS-based methodology for conducting rapid assessments of pesticide and nutrient transport within agricultural watersheds was recently developed. This methodology is based upon the use...
