    abstract = {In this study, the maximum downwind distance
xmax was calculated according to the dispersion parameters
and by using four methods the power law function,
standard, Klug and Pasquill-Gifford method sat three
effective heights of 5, 100 and 250 m, respectively. The
maximum ground level concentration of air pollution that
based on the Gaussian model can be calculated by using
the estimated and actual values of the x<sub>max</sub> for different
stability classes. The estimated and actual x<sub>max</sub> are
summarized as 0-492 m in power law and standard
method, also the percentage of the error between
estimated and actual maximum downwind distance in the
range of 0.005-14.2, respectively. Comparison between
the results of estimated and actual x<sub>max</sub> in case of power
law and standard method with the previous work used
Brigg method (Ronbanchob2015) is carried out.}
