According to the spatial movements of the Nak-dong river watershed, the changes in heavy metal concentrations were simulated by WASP7.3. The risk assessment was performed using the predicted data of WASP7.3. The target heavy metal was manganese (Mn). In the simulated manganese data of WASP7.3, the average concentration by regions was from 0.03 mg/L to 0.07 mg/L. It is lower than drinking water standard in korea. The risk assessment was presented that it was high at the junction of Nak-dong river and Kumho river. It was influenced by the discharge of industrial complexes and large cities which were located in the junction. In comparison of drinking water standard and predicted data of WASP7.3 risk assessment, whole watershed was also low level at predicted data. However, to keep the similar risk value ($10^{-7}$) in adults and children anywhere, it requires the additional treatment of the point source discharges. It was also reflected by regions. Through this study, it was possible to evaluate heavy metal influence in unattainable monitoring regions and to estimate heavy metal addition and reduction by locations. Therefore, the outcomes of WASP7.3 can connect with the risk assessment and it can evaluate the safety of human by regions.
