Thus, a data set of joint flood control risks and power generation benefits of reservoirs and flood storage and detention areas was formed. This dataset provides a basis for improving the joint flood control capacity of reservoirs and flood storage and detention areas and coordinating decision-making of flood control capacity.
\r\n1. The power generation benefit analysis table contains the corresponding data relationship between the flood control capacity of different reservoirs and power generation benefits, where the unit of storage capacity is 100 million m3, and the unit of power generation benefit is 100 million yuan;\r\n
2. The flood storage and detention area inundation loss table contains the corresponding data relationship between the flood control capacity of different flood storage and detention areas and the flood storage and detention area inundation loss, in which the unit of storage capacity is 100 million m3, and the unit of inundation loss is 100 million yuan;\r\n
3. For example, the \"50000+3+220\" table contains the corresponding data relationship between different reduced flood control storage capacity and total inundation losses. For example, the table name \"50000+3+200\" means that the calculation environment is a safe flow rate of 50000m3, the loss coefficient is 3, and the flood control storage capacity of the Three Gorges Reservoir is 22 billion m3. The \"0, 10,..., 50\" in the first row represent the reduced flood control storage capacity in the flood storage and detention area, and the first column represents the cumulative probability. The eighth column \"CVaR\" represents the conditional risk value under different confidence levels when the flood control capacity of the flood storage and detention area is maximum, and the remaining data represents the risk losses corresponding to different cumulative probabilities, in units of 100 million yuan.", "ds_time_res": "", "ds_acq_place": "Three Gorges and Qingjiang River Basin", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
