Description

Our previous papers presented the practical system to predict pollutant dispersion in a complex terrain. The study included the field experiments conducted in such region.<BR>At first the field of wind flow in an area concerned is determined by a modified potential flow model. Second the ground level concentration is calculated by the modified plume model.<BR>This paper presents the effect of various parameters in the wind field model on calculated wind field in comparison with the observation of the experiments in Tochigi area.<BR>As a result of analysis, the desirable parameter of power law is estimated to be 0.14 and the pseudo-resistance parameter 1.0 to calculate the wind field in neutral condition in Tochigi area by the proposed model. Though the effect of wind boundary condition seems to be significant, the proposed model is found to be applicable when the above mentioned parameters are determined properly.
