Flood forecasting system of river system

Abstract

The invention provides a flood forecasting system of a river system. The flood forecasting system comprises a river system setting module, a data acquiring module, a parameter calibration module and a forecasting system, wherein the river system setting module is used for setting the upstream-downstream topological relation of all sub-catchment of the river system; the data acquiring module is used for acquiring the real-time rainfall value and real-time flow value of all the sub-catchment of the river system and historical flood data during floods; the parameter calibration module is used for calibrating the parameters of a preset forecasting model according to the historical flood data; the forecasting module is used for acquiring a forecasting result of all the sub-catchment of the river system according to the upstream-downstream topological relation, the real-time rainfall value and real-time flow value of each sub-catchment, a preset future rainfall value, a preset upstream sub-catchment reservoir regulation manner of each sub-catchment and the parameter-calibrated forecasting model. By the flood forecasting system high in efficiency, flood forecasting can be performed on multiple sub-catchment of the river system.

Description

technical field [0001] The invention relates to the technical field of flood forecasting, in particular to a river system flood forecasting system. Background technique [0002] Flood disasters in my country are sudden, frequent and uncertain, and they pose a serious threat to human survival and development. Therefore, flood control issues have attracted more and more attention. In the process of dealing with flood disasters, flood forecasting is one of the important tasks of flood control and disaster reduction, and its results can provide scientific support for flood control engineering system scheduling and flood control decision support. Therefore, the flood forecasting system came into being. [0003] Current flood forecasting systems use a single river basin as the main target for flood forecasting. [0004] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: [0005] The workload...

AI Technical Summary

Problems solved by technology

[0005] The workload of flood forecasting for large-scale basins and multiple basins is very heavy, especially when reservoir scheduling is involved in the basin. The flood in the downstream basin is usually composed of the superposition of upstream basin water flow, reservoir discharge and upstream and downstream interval water flow. The efficiency of flood forecasting using the existing flood forecasting system is low
