Abstract

The invention relates to a dual-core dual-drive flood forecast method. The dual-core dual-drive flood forecast method includes hydrological mode selection; runoff producing parameter calibration; confluence parameter calibration; rainfall uniformity determination; zone dividing; runoff producing calculation; confluence calculation; superposition; and forecast result issue. The dual-core dual-drive flood forecast method for non-uniform rainfall divides a drainage basin into a rainstorm core zone and a non-rainstorm core zone according to spatial distribution of non-uniform rainfall centers on the basis of rainstorm food features of semi-humid semi-arid regions and arid regions, establishes hydrological modes to perform runoff producing calculation and confluence calculation, fully utilizes rainfall distribution information of each rainfall site in the drainage basin during rainstorm, considers differences of the soil water content in drainage basins at the beginning of rainfall, is simple, and is easy to operate.

Description

technical field

[0001] The invention relates to a dual-core and dual-drive flood forecasting method, which is a real-time hydrological forecasting method and a real-time flood forecasting method aiming at non-uniform precipitation through modeling. Background technique

[0002] For the distribution of a rainfall process on the watershed, unevenness is absolute, while uniformity is relative. In humid regions, where annual rainfall is high, the water content of the surface soil layer is high and relatively uniform. Due to the climatic conditions, it is easy to form a large area of ​​rainfall, which makes the distribution of rainfall in the basin relatively uniform. However, in semi-humid, semi-arid or arid regions, not only is the distribution of rainfall concentrated within a year, but the distribution of a rainfall process on the watershed surface is often very different, and local torrential rains occur frequently. The runoff at the outlet section of the watershed is ofte...
