IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
Total Maximum Daily Loads (TMDL) management system is a policy in new era to achieve both the development and
conservation of watershed through a scientific method different from conventional one which focuses only on regulations
for the conservation of water quality. Recently, sixteen weir were built in four major rivers as part of the river environment
change business and of those sixteen, eight of the hydraulic structures (multi-functional weirs) were installed and
dredged in Nakdong River which caused the change of the river cross-section. It eventually led to the change of river
environment and hydraulic properties such as hydraulic retention time, river cross-section, longitudinal section of
stream, water level, energy grade, flow velocity. The characteristics of river are mostly affected by hydraulic and
hydrologic characteristics. Therefore, one should consider the importance of hydraulic properties which influence water
quality prediction during water quality modeling.
In this research, we have applied new hydraulic properties by the change of river environment and conducted
water quality modeling in order to predict target water quality and water quality prediction using pollution load
reflecting the pollution source, i.e., population, sewage treatment plant in unit watershed along with TDML in
Nakdong River, Korea
