J. Agri. Fore. 2013. 62(3): 173-201 - 173 - The Study on Estimation of Fugitive Dust Quantity of Estuary in Wu River Using FDM 應用 FDM模式推估烏溪河口揚塵量之研究 Long-Ming Huang 1) Yen-Hsun Chao 2) Tai-Sheng Chang 3) 黃隆明 趙彥勛 張台聖 more capable of producing better results. As for Abstract the selection of weather data, the order for the The purpose of this study is using FDM stations is Sinjhuang Elementary School, Xitun, (Fugitive Dust Model) to simulate and estimate the Changhwa, Shalu, and Siansi. The FDM model fugitive dust quantity of estuary in Wu River. In execution results show that when the total bare 2 this study, wind tunnel testing was conducted. land area source area equals to 2,130,855m , the Ten measurement points were set along the section simulation value of the fugitive dust quantity is 3 of wind tunnel height and using control volume 8.1μg/m -hr, a mere 9.5% deviation from the 3 method to re-establish the relation between Wu reference base value of 7.4μg/m -hr. Hence it is River fugitive dust quantity (PM10) and wind feasible to use the FDM for the estimation of speed: E=5.63×10-7U2.6952 . To cope with fugitive dust quantity of estuary in W
