Short summary
The Korean government has tried to create and is tasked with implementing programs designed to repair the damage already done to the environment in the Han River basin. However, there is an absence of an integrated approach method for considering water supply, water quality improvement, and natural ecosystem maintenance. The objective of the study is to conduct integrated watershed health assessment of the natural environment, hydrology, water quality, and aquatic ecology of the Han River basin.
