Embodiment 1

[0060] like figure 1 As shown, in the present embodiment, 1, a kind of method for forecasting and early warning of mountain torrents based on digital twin is provided, it is characterized in that: comprise the following steps,

[0061] S1. Construct a digital twin database; perceive and obtain meteorological data, hydrological data, soil data and topographic data of the target watershed in real time, and transmit them to the digital twin database in real time to realize the dynamic update of the digital twin database; and collect the target watershed The meteorological data, hydrological data, soil data and terrain data of the historical stage are stored together in the digital twin database;

[0062] S2. Build a digital twin watershed; based on the digital twin database, build a digital watershed simulator with a gridded hydrological and hydrodynamic model as the core, coupled with a real-time assimilation module and a digital sand table, and generate a digital twin watershed...

Abstract

The invention discloses a mountain torrent forecasting and early warning method and system based on digital twinning, and the method comprises the following steps: constructing a digital twinning database; constructing a digital twinborn basin; on the basis of collecting multi-source rainfall forecast products, generating a future ensemble average rainfall forecast result by adopting a geometric averaging method, forming rainfall ensemble forecast by the future ensemble average rainfall forecast result and a single rainfall forecast product, and updating future rainfall data in the digital twin database in real time; coupling rainfall ensemble forecasting with the digital twinborn basin to achieve mountain torrent rolling forecasting; and based on a mountain torrent forecast result, intelligently identifying a mountain torrent risk level according to an early warning grading standard, generating an early warning decision and sending out early warning information. The method and system have the advantages that the problem that an existing mountain torrent forecasting and early warning method cannot accurately describe and reflect current and future conditions of a drainage basin at the same time is solved, mountain torrent disaster early warning information can be accurately provided, the risk level can be dynamically evaluated, and an early warning decision can be automatically issued, so that mountain torrent disaster defense work can be smoothly carried out.

Description

technical field [0001] The invention relates to the technical field of mountain torrent disaster early warning, in particular to a method and system for mountain torrent forecast and early warning based on digital twins. Background technique [0002] Flash floods generally refer to sudden floods caused by precipitation in small and medium-sized watersheds in hilly areas. my country has many mountains, uneven distribution of precipitation, and frequent rainstorms. Therefore, mountain torrent disasters have the characteristics of high frequency and great destructive power, which pose a serious threat to the local environment and the safety of residents' lives and properties. Therefore, flash flood warning has always been the focus of scientific research and operational work. At present, the commonly used early warning methods mainly include: static critical rainfall, dynamic critical rainfall, hydrological model method, etc. [0003] Critical rainfall method is the most wide...
