| 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,本文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“数字汇聚中心-数字流域建设-智慧孪生体-四预能力建设”为主体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,采用水文水动力模型与防洪调度模型耦合模拟、一体化模型与系统数据实时交互、二三维地理信息动态展示等关键技术,构建了基于“四预”体系的永定河洪水预报调度系统,为永定河洪水调度预演提供技术支撑。 |

| 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 the overall architecture of flood forecasting and control system based on "digital convergence center-digital watershed management-intelligent twins-‘four forecasts’ capacity building", and combs the business function and logic of the system. Combined with the present situation of river system and flood control project in 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 Yongding River based on " four forecasts" is constructed to provide support for flood dispatching decision-making of Yongding River. |
