Yuanshan reservoir water storage

How much water is stored in Chinese reservoirs?

Results show that the multiyear-averaged water storage of all Chinese reservoirs at the maximum water area is estimated at 784.60 km 3 from 2017 to 2022, and the water storage at the year-long water area is approximately 318.86 km 3.

Which reservoir has the largest water storage in China?

We further calculated the NS for the Three Gorges Reservoir (the reservoir with the largest water storage in China) and Danjiangkou Reservoir (the water source of Chinese South-to-North Water Diversion Project) at different water storage states (Fig. 12).

Is water storage regulated in large-scale reservoirs in China?

One of the most intensive human-induced alterations of the hydrological cycle is the regulated water storage in reservoirs, however, its quantification in large-scale reservoirs in China is inadequate. The lack of such information limits the rational management and utilization of water resources in reservoirs.

What factors influence reservoir water storage in China?

Inter- and intra-annual variability in reservoir water storage is mainly influenced by natural inflow in Northeast and Northwest China, while anthropogenic factors dominate in the YR, Eastern, and Southwest China. Reservoirs can supply water, control flood and provide electricity.

How much water does a reservoir store?

We estimated the water storage of all reservoirs corresponding to different WFs in 2017–2022. Similar to the trend of area change, the total annual maximum water storage of reservoirs fluctuated between 741.08 and 819.97 km 3 from 2017 to 2022 (Fig. 4 b), with the highest value recorded in 2022.

Where are Sichuan reservoirs located?

For example, reservoirs in Sichuan province are clustered along the main stems of Fujiang River, Jialing River, and Yangtze River. In addition, as a major water supply, many reservoirs are concentrated in urban areas such as the Shandong Peninsula urban agglomerations.
