基于“四预”的永定河洪水预报调度系统研究与应用

Development and application of Yongding River flood forecasting and dispatching system based on “four forecasts” system

  • 摘要: 近年来,我国洪水频发,对人民群众的生命财产安全造成了严重的威胁。为能够提前研判洪水态势,减轻洪灾损失,依照水旱灾害防御的业务特点,遵循预报、预警、预演、预案的理念,提出了以“数字汇聚-数据底板-孪生平台-四预体系”为主线的洪水预报调度系统总体架构,梳理了系统的业务功能与需求。结合永定河流域特点,采用流域洪水预报调度、模型与系统实时交互和二三维地理信息渲染展示等关键技术,构建了基于“四预”体系的永定河洪水预报调度系统,支撑永定河洪水调度预演,为洪水预报调度“四预”体系的建设提供借鉴与参考。

     

    Abstract: In recent years, floods occur frequently in China, which poses a serious threat to the safety of people’s lives and property. To study and judge the flood situation in advance and reduce flood losses, according to the operational characteristics of flood and drought prevention and following the concepts of “four forecasts”, this paper puts forward an overall architecture of flood forecasting and control system based on “digital convergence - data backplane - twin platform - four pre-system”, and combs the business function and logic of the system. Based on the present situation of river system and flood control project in the Yongding River Basin, key technologies such as coupling simulation of hydrological hydrodynamic model and flood control operation model, real-time interaction between nested model and system data, and dynamic display of two- and three-dimensional geographic information are adopted, and a flood forecasting and control system of the Yongding River based on “four forecasts” is constructed to provide support for the flood dispatching decision-making of the Yongding River.
