Flood prevention and disaster reduction benefits analysis of pre-release capacity improvement in Ningbo Zhougongzhai-Jiaokou Cascade Reservoir
The pre-release capacity improvement project of Zhougongzhai-Jiaokou Cascade Reservoirs in Ningbo City improved the pre-release capacity of the two reservoirs effectively.During the defense process of 2212 typhoon"Meihua",the reservoir was optimized for pre-release scheduling,and the reservoir water level was dynamically adjusted quickly,which successfully prevented the over-standard flood(rainfall),and the pre-release capacity improvement project played an important role.By calculating and deducing the pre-release scheduling of Zhougongzhai Reservoir and Jiaokou Reservoir during Typhoon"Meihua",the flood control and disaster reduction effect of Zhougongzhai-Jiaokou Cascade Reservoir pre-discharge capacity improvement project and the benefits obtained were analyzed,which provided technical support for the pre-release scheduling of river basin cascade reservoir,and also provided reference for the function improvement and pre-release scheduling of similar cascade reservoirs(groups).
