黄河三门峡至花园口区间(简称三花间)是当前威胁下游防洪安全的主要洪水来源地区。为增长该区洪水预报预见期,发挥已建工程的防洪效益,一九七八年来由黄委会科技办公室负责,组织力量进行改善该地区水情、雨情数据收集和洪水预报作业系统的研究。一九八○年十二月经外经部和联合国开发计划署批准,列为由开发署提供技术、设备援助的项目,帮助完成建设三花间自动测报系统的第一期工程。
The Yellow River Sanmenxia to Huayuankou interval (hereinafter referred to Sanhuajian) is the current flood threat to the downstream flood control areas. In order to enhance the flood forecast benefit of the flood forecast in this area and take full advantage of the flood control benefits of the existing projects, the Office of the Science and Technology Commission of the Yellow River Council has been responsible for organizing the research on hydrological and rainfall data collection and flood forecasting systems in the area in 1978. Approved by the Ministry of Foreign Economic Relations and the United Nations Development Program in December 1980 as a project funded by UNDP to provide technical and equipment assistance, the first phase of the construction of the Sanhuada Automatic Report System was completed.
