The watershed health, vulnerability and recovery potential for determining protection and restoration priorities were assessed for the Han River basin (34,148 km²) in South Korea. Six components, including the watershed landscape, stream geomorphology, hydrology, water quality, aquatic habitat conditions, and biological conditions, were used to evaluate the watershed health (basin natural capacity). The Soil and Water Assessment Tool (SWAT) was utilized to examine the hydrology and water quality components in the study basin, which includes 237 sub-watersheds, three multipurpose dams, one hydroelectric dam, and three multifunction weirs. Four components, namely, the future impervious area, future climate conditions, future water use, and recent land cover changes were used to evaluate the watershed vulnerability to artificial stressors. We determined the protection and restoration priorities by evaluating and comparing the health and vulnerability of each sub-watershed. Sixty-seven sub-watersheds out of 237 were classified to have restoration priorities with high recovery potentials.

对汉江流域（34,148 km ²）在韩国。流域景观，河流地貌，水文，水质，水生生境条件和生物条件等六个组成部分被用来评估流域健康（流域自然容量）。利用土壤和水评估工具（SWAT）来检查研究盆地中的水文和水质成分，包括237个子集水区，三个多功能水坝，一个水力水坝和三个多功能堰。四个要素，即未来的不渗透区域，未来的气候条件，未来的用水量和最近的土地覆被变化被用来评估流域对人工压力源的脆弱性。我们通过评估和比较每个子集水区的健康和脆弱性来确定保护和恢复的优先顺序。
