Study on the Flood Real-time Forecasting Correction Model of Luhun Reservoir

The function of flood real-time forecasting correction model is to reckon the error between inflow amount and predictive value based on reservoir water level present observations; or to correct the forecast of flow process based on the error between river hydrological observation stations and forecast flow, in order to improve the accuracy of real-time flood forecasting. Flood forecasting adaptive real-time model is used in the correction model, model parameters are handled by variable forgetting factor recursive least squares algorithm, adaptive dynamic tracking. This paper completed the real-time forecasting correction modeling of Dongwan and Luhun station based on original prediction model.
