HHSW·NUG-1型光电测沙仪在黄河干流典型站的应用研究
Application Research of the HHSW·NUG-1 Photoelectric Sediment Meter at Typical Stations in the Main Stream of the Yellow River
摘要
Abstract
The Yellow River is characterized by its scarce water resources and abundant sediment,leading to an imbalance between water and sediment dynamics.With the advancement of hydrological monitoring and forecasting capabilities,there have been significant strides in water level and flow monitoring.However,sediment concentration monitoring technology has yet to see a breakthrough.In order to slove the issue of sediment monitoring,the Hydrology Bureau of the Yellow River Conservancy Commission developed the HHSW·NUG-1 photoelectric sedi-ment meter.This instrument overcame the limitations of traditional optical sediment measurement methods,which were constrained by flow velocity and range requirements.It enabled year-round online continuous monitoring,providing stable and highly accurate data.This paper fo-cused on the comparative testing and application of this instrument at the Xiaolangdi and Huayuankou hydrological stations on the Yellow Riv-er.The study found that during the comparative testing period,the Xiaolangdi Reservoir is undergoing regulation,resulting in significant wa-ter and sediment processes and favorable sediment conditions.The performance of the photoelectric sediment meter is relatively stable,with no abrupt changes in sediment data.The overall trend of the data from the photoelectric sediment meter is consistent with the unit sediment concentration.The photoelectric sediment meter is capable of real-time online monitoring of sediment concentration data,accurately capturing the rise and fall processes and trends of sediment concentration.This aids in the rational arrangement of sediment discharge measurements at the stations,allowing for more precise judgments on abnormal sediment conditions and peaks,and the rational scheduling of tests.This not only reduces labor intensity but also enhances the rationality and timeliness of the testing process.关键词
