*4.1. Flood Control Capacity (FCC)*

FCC scores 84.9 points nationwide, which is at a medium-high level. The overall flood control capacity nationwide is: the overall RWA reached a medium-high level, and although DRC is still at a medium level, the impact of floods on the security of lives and properties of the people along the rivers was significantly reduced. Nationally, the sense of security of the people along the rivers was effectively guaranteed, laying a foundation for achieving the vision of "a peaceful life with secure rivers".

FCC evaluation results for the first-grade water resource zones are shown in Figure 3. Specifically, FCC scores for the Taihu Lake, the Yellow River, the Huaihe River, the Songhua River, and the Yangtze River all exceed 85 points, reaching a good level, and exceed 80 points for the Pearl River, the Haihe River, the Liaohe River, southeastern rivers, and

#### northwestern rivers, staying at a medium-high level. Southwestern rivers score less than 80 points on FCC, representing a medium level. *Water* **2022**, *14*, x FOR PEER REVIEW 11 of 20

#### *4.2. Water Resources Reliability (WRR) 4.2. Water Resources Reliability (WRR)*

WRR scores 77.1 points nationwide, which is generally at a medium level. The overall water resource reliability nationwide is: AWP stands at a medium-high level against the international warning line for water shortage, WSR is at a good level, and WUR is well below 40%, but water resources are unevenly distributed across regions, which is incompatible with population distribution and allocation of productive forces; the level of water conservancy is yet to be further improved, and there is a clear gap in GDP Output per cubic meter of Water use (GOW) compared with high-income countries; and CSD is generally at a medium-low level. Continuing to play the basic role of happy rivers and lakes to achieve the vision of "an affluent life with reliable water supply" is still on the way.

WRR evaluation results for the first-grade water resource zones are shown in Figure 4. In general, scores in the north are lower than in the south. Specifically, scores for the Yellow River, the Haihe River, the Huaihe River, northwestern rivers, and the Liaohe River are all below 70 points, at a medium-low level. Scores for southeastern rivers and the Taihu Lake are higher than 80 points, reaching a medium-high level. WRR evaluation results for the first-grade water resource zones are shown in Figure 4.
