AB  - This dataset is aimed at the dynamic control of the operating water level of the Three Gorges Reservoir in flood season. It collects reservoir dispatch simulation results under typical flood processes, different forecast information organization methods (single forecast, multi-scale forecast coupling) and different forecast uncertainty levels. The data includes time series data such as inflow flow, discharge flow, reservoir water level and upper and lower limits of the control region on a 6-hour scale, and provides statistical indicators such as discrete scenario probability of forecast error and maximum/average water level under different forecast periods. It can be used to evaluate the application effect of multi-scale forecast information in dynamic control of the Three Gorges Reservoir during flood season, and provide data support for the comparison and selection of water resource utilization and joint dispatch plans under flood risk constraints. The data files are Excel workbooks, organized into multiple Sheets according to research scenarios, mainly including:1) Forecast uncertainty parameters and scenario probability:- Sheet2: The discrete value of the forecast error multiple ratio x (-1.0 ￣ 1.0, step size 0.1) and the probability of different pass rate scenarios (40% ￣ 85%, etc.).- "Uncertainty Change" Sheet: Give statistics such as pass rate α ( %), allowable error (0.2), mean square error σ calculated back from normal distribution, and maximum/average water level under different foreseeable periods.2) Three Gorges Reservoir dispatch simulation time series results (typical flood process): Sheets such as "Multi-scale 1954- 100a Mapping" and "Multi-scale 2020 Mapping": Dispatch process line with 6 h time steps.Key field meanings: Time (time/time period number); inflow-×× (Three Gorges inflow flow, m³/s); outflow-×× (discharge flow, m³/s); water level-×× (reservoir water level, m); Abandoned water (abandoned water flow, m³/s); Lower limit/upper limit of the co
