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, ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

Support to Aviation Control Service (SACS): an online service for near-real-time satellite monitoring of volcanic plumes

by NILU - The Norwegian Institute for Air Research  (May 16, 2014)

Volcanic eruptions emit plumes of ash and gases into the atmosphere, potentially at very high altitudes. Ash-rich plumes are hazardous for airplanes as ash is very abrasive and easily melts inside their engines. With more than 50 active volcanoes per year and the ever-increasing number of commercial flights, the safety of airplanes is a real ...

Calculations of external irradiation from radioactive plume in the early stage of a nuclear accident

by Inderscience Publishers  (Dec. 28, 2012)

A mathematical method for real–time calculations of cloudshine doses/dose rates used for purposes of online assimilation of model predictions with observations incoming from terrain is proposed. Model predictions of cloudshine doses have to be calculated simultaneously in an array of positions located on terrain around a nuclear facility. A ...
