Title:
MULTI-STEP FLOOD FORECASTING METHOD AND APPARATUS BASED ON GRU-SEQ2SEQ
Document Type and Number:
WIPO Patent Application WO/2024/021966
Kind Code:
A1
Abstract:
The present invention provides a multi-step flood forecasting method and apparatus based on GRU-Seq2Seq. On the basis of a GRU model, a GRU algorithm is improved, a Seq2Seq model is introduced, measured rainfall data and simulated runoff data are together inputted into a GRU encoder to obtain an encoding vector, and then the encoding vector is inputted into a GRU decoder to obtain predicted flow. By means of a GRU-Seq2Seq flood forecasting model, rainfall runoff information under the impact of typhoons can be fully mined, an accurate multi-step-ahead flood forecasting model is established, the problem of time lag in multi-step-ahead prediction is solved, and the effect of the flood forecasting model is effectively improved.
