Trihalomethanes in Chlorinated Sacramento-San Joaquin Delta Drinking Water Simulated with the EPA WTP-THM Model
Trihalomethane (THM) concentrations at a representative water treatment plant simulated with the EPA Water Treatment Plant THM (WTP-THM) model were used to assess potential drinking water...
Quantification of the Mechanisms Controlling the Removal Rate of Volatile Contaminants by Air Sparging
Air sparging is a technology for removing dissolved and volatile phase chemicals (VOCs) from the saturated zone. It is used in conjunction with soil vapor extraction (SVE) and sometimes...
Plain flooding: near field and far field simulations
The paper deals with the problems met in the attempt of simulating the plain submersion produced by a levee breaking in the inertia dominated region (near field), scaling with the typical...
Two-Dimensional Dam-Break Flow Simulation in a Sudden Enlargement
The paper presents the use of a two-dimensional depth averaged mathematical model for an unsteady dam-break flow simulation in a sudden enlargement. Continuity and two momentum equations...
Interactive Models for the Regulation of Lake Ontario
Extensive studies are underway to improve the regulation of Lake Ontario. These studies not only involve the inclusion of factors and interest groups not previously considered, but also...
Near Field Behavior of a Far Field Circulation Model
Output from the 3-D far field circulation model ECOMsi was compared with output from EPA initial mixing models in two simulations of coastal sewage outfalls - an idealization with steady...
Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...
High-Resolution Upwind Schemes for Solving Mass Transport Equation
A fractional-step algorithm is employed to solve the mass transport equation by decomposing the advection-dispersion equation into two portions, pure advection and pure dispersion. High-resolution...
Treatment of Nonhomogeneous Terms in Flow Models
A study of the relative significance and treatment of nonhomogeneous terms in unsteady open-channel flow simulation models has been conducted. The effects of nonhomogeneous terms including...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
On Habitat Simulation in Mountain Rivers
Mountain rivers are quite different from other rivers and one of the characteristics that distinguish them from others is the large variation in velocities with time, with location in...
Multi-Reservoir System Simulation Design Using C++ and Object Oriented Programming
Scientists and Engineers intuitively perceive the world as objects with interactions and internal processes. Physicists may view there work as different particles exerting forces on each...
An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...

Travel Demand with Forecasting Microsimulation
Transportation planners forecast travel demand using techniques that are based on dissagregate models estimated from cross-sectional data. Their forecasts are usually single future time...
Using Interactive Simulation to Model Driver Behavior Under ATIS
This paper discusses the development and implementation of FASTCARS (Freeway and Arterial Street Traffic Conflict Arousal and Resolution Simulator), an interactive microcomputer based...
Use of TRAF-NETSIM to Estimate the Traffic Impacts of an Urban-Resort Area Development
Urban-resort areas are concentrated visitor destination districts that are located within or in close proximity to urban areas. The combination of visitor-related and urban activities...
The Integration of the Highway Capacity Manual and the TRAF-NETSIM Simulation Model
