Abstract
While studies have been actively conducted to build a prediction system of dust diffusion at
a large-scaled reclaimed land the objective of this study is to develop an aerodynamic numerical
model to collect fundamental data for the studies. Saemangeum area, the experimental place of this
study, is located at the western costal area, and its total area reach to 28,300ha. CFD model were
developed to overcome the difficulties of field experiment depending on very limited measuring
points as well as dealing with the spacious area. The 3-D CFD model is designed with dust
generation computed by the local GIS data is used to design the topography of Saemangeum area.
All the seasonally collected data were used as the CFD input data as well as to improve the accuracy
of the developed CFD model. The experimental results indicated that dust generated at
Saemangeum is diffused very extensively and strongly depended on weather condition. Moreover,
the dust contain salty contents which can be very harmful to plant production while the dust itself
causes respiratory and eye diseases for human and animals. Through this study, it is recognized that
the aerodynamic simulation can be very effective tool to build the prediction and alarm system of
dust diffusion.
