that the determination of EMCs (equation 4.3) would be of importance with respect to
pollutants, which are transported in particulate form and are associated with suspended
matter. Also, these findings confirm the trend of correlation found in the previous section.
The higher concentrations of COD and TSS at the end of the storm event could be
associated with heavier particles and debris, which have not been carried out with the
flow, but remain in the channel after the storm wave subsides.
The characteristic parameters of this storm event are presented in Table 4.3. EMC was
calculated by equation 4.3, and the flushing effect of the storm was calculated based on
cumulative load curves (Choe
