Model comparison in simulating the atmospheric dispersion of a pollutant plume in low wind conditions

by Inderscience Publishers  (Oct. 13, 2012)

This study investigates the performance of different air pollution dispersion models in low wind conditions. The models have been applied to two sites frequently characterised by weak winds: the cities of Modena and Reggio Emilia, in the Po River Valley (Northern Italy). The emission sources are the municipal waste incinerator (Modena) and a ...

Comparative study of fecal bacterial decay models for the simulation of plumes of submarine sewage outfalls

by IWA Publishing  (Aug. 8, 2013)

In the literature, analytical models have been shown to be extremely useful for estimating the decay rates of coliform as fecal indicator microorganisms, providing reliable predictions of bathing conditions in coastal and continental waters. Although a number of different formulations have been developed in the literature, each one may only be ...

Using plume rise schemes to model highly buoyant plumes from large fires

by Inderscience Publishers  (Feb. 8, 2011)

The atmospheric dispersion model Numerical Atmospheric-dispersion Modelling Environment (NAME) is used to simulate the smoke plume from the explosion at the Buncefield oil depot. Simple modelling, in which the plume rise is included through an effective elevated source term, captures the transport and spread of the plume well. More complex ...

Prescribed burn smoke impact in the Lake Tahoe Basin: model simulation and field verification

by Inderscience Publishers  (Dec. 30, 2013)

Smoke dispersion modelling based on the Fire Emission Production Simulator and the Hybrid Single Particle Lagrangian Integrated Trajectory (FEPS-HYSPLIT) model was applied to prescribed burns in the Lake Tahoe Basin (LTB) during fall 2011. This, in conjunction with measurements at sources and real-time ambient PM 2.5 monitoring around LTB, ...

The plume model MODIS: integration in the Hydro-Quebec shell

by Inderscience Publishers  (Sep. 17, 2009)

The comprehensive numerical model MODIS for the simulation of pollutant dispersion from a point source is integrated in the graphical shell of Hydro-Quebec. The shell has been developed by Hydro-Quebec to offer a valuable scheme for various applications of software products, which were originally conceived only for scientific purposes. MODIS, ...

Characterising uncertainty in plume dispersion models

by Inderscience Publishers  (Sep. 1, 2005)

For management decisions related to effects of releases of toxic chemicals, it is useful to consider not only the expected or most likely impact of the release, but also the envelope of possible outcomes, the latter of which involves an assessment of the uncertainty in the modelling results. In this paper, we provide quantitative estimates of ...

An agent-based modeling framework for sociotechnical simulation of water distribution contamination events

by IWA Publishing  (Jun. 25, 2013)

In the event that a contaminant is introduced to a water distribution network, a large population of consumers may risk exposure. Selecting mitigation actions to protect public health may be difficult, as contamination is a poorly predictable dynamic event. Consumers who become aware of an event may select protective actions to change their water ...

A fluctuating plume model for pollutants dispersion with chemical reactions

by Inderscience Publishers  (Oct. 13, 2012)

A fluctuating plume model for pollutant dispersion is developed. The model is able to include chemical reactions, accounting for segregation. The model is tested against measured data in wind tunnel experiment, where NO is emitted from a source in an environment of ozone. The results are presented in terms of the plume centre line dispersion and ...

Numerical Simulations on Aerodynamics of Thermally Induced Plumes

by SAGE Publications  (Mar. 1, 2008)

Since the physics of air entrainment is not yet clearly understood, most of the fire plume expressions reported in the literature were derived empirically. Experiments with different fire geometry, fuels, and ambient conditions would be difficult when trying to derive comprehensive plume temperature and velocity fields from existing theories. ...
