Environmental cost benefit analysis for a coal-fired power plant: An application of dispersion modelling coupled with GIS

摘要

In this study, local air quality impacts of a proposed conventional coal-fired pwoer at Icel region has been ivestigated using numerical dispersion modeling studies coupled with a GIS application. Within the impact area of the facility, Industrial Source Complex Short Term (ISCST2) dispersion model has been used to estimates ground level concentrations of air pollutants originating from the power plant. For the same impact area, GIS applications have been utilized to determine the agricultural yield distribution. For this purpose, relevant satellite images were digitized, classified and statistically analyzed. Based on the predicted ground level pollutant concentrations and sensitivity of the agricultural crops to those, agricultural yield loss was estimated for the impact area.
