Abstract
In case of studied area located around the sea, the data measured from the regionalmeteorological office is highly different from the local weather data because the diffusivity offugitive dust varies considerably with meteorological conditions. Especially, it is very difficultto predict the amount of fugitive dust accurately as wind speed remains high frequently. In thisconsider the effect of wind speed on the amount of fugitive dust generated from thereclamation site. The amount of fugitive dust estimated as mentioned above was simulated byusing ISCST3 model. As a result, in case of using only the Fugitive Dust Formula which isusually used in Environment Impact Assessment, the predicted PM10 concentrations withpoints were 43.4~67.8mg/m 3particulates, the predicted values of PM10 with points were 43.3~69.1mg/m 3, 49.5~90.4mg/m 3and 76.0~182.6mg/m 3 with the wind speeds of 4.4, 5.8 and 7.7m/s, respectively. It could bepossible to predict the amount of fugitive dust accurately because these predicted values werefugitive dust in this area damaged by fugitive dust which is caused by wind.
