### Assessment of Climate Change Vulnerability
#### 3.2.4 SSP-585 Scenario  
The CCVI was determined using the climate change exposure and the sensitivity and adaptive capacity from the sub-watershed calculations for the SSP-585 scenario. The results are presented in Table 14.  
The highest climate change exposure for the SSP-585 scenario was 81.73 in the Nakdong Estuary sub-watershed and the lowest was 22.15 in the Geumhogang sub-watershed. Similarly, the highest CCVI was 66.45 in the Geumhogang sub-watershed and the lowest was 18.50 in the Wicheon sub-watershed. The CCVI results by sub-watershed according to each scenario are shown in Figure 3. The spatial distributions of the CCVI by scenario were similar because the sensitivity and adaptive capacity did not only change under changes in the climate exposure according to the climate change scenario. The CCVI was high in the Naeseongcheon sub-watershed upstream of the Nakdong River, the Geumhogang sub-watershed in the midstream of the Nakdong River, and the Namgang and estuary sub-watersheds in the downstream of the Nakdong River. The CCVI was low in the Andong Dam, Imha Dam, Habcheon Dam, and the Wicheon sub-watersheds in upstream and midstream Nakdong River. The high CCVI observed in the Geumhogang sub-watershed might be because of its low exposure to climate change and its high adaptive capacity that results from the high percentage of seaweed population and the capacity for sewage treatment owing to urbanization. Although the highest climate exposure was observed in the estuary, its CCVI was high due to the low sensitivity and high adaptive capacity that result from urbanization, as with the Geumhogang sub-watershed. Low CCVIs were derived for the Wicheon, Hoecheon, Nakdong Gumi, and Hwanggang sub-watersheds because of the low percentage of seaweed population and low capacity for sewage treatment in these areas. \begin{table}

Table 14: Climate change vulnerability in the SSP-585 scenario. The sensitivity for each SSP scenario associated with each proxy variable for the Geumhogang sub-watershed, and the Wicheon sub-watershed, with the highest and lowest CCVI, respectively, in every scenario, is represented graphically in Figure 4.  
Figure 3: Spatial distribution of CCVI by Nakdong River sub-watershed (the closer to blue, the higher the CCVI, the lower the vulnerability to climate change; and the closer to red, the lower the CCVI and the higher the vulnerability to climate change). **(a)** ssp-126, **(b)** ssp245, **(c)** ssp-370, and **(d)** ssp-585. As shown in Figure 4, the CCVI became lower (vulnerability increases) as (E) and (S) extended closer to 100, and the CCVI became lower as (A) became closer to 0.
