广西河流水平式ADCP流速关系模型研究及应用

Study and application of horizontal ADCP flow velocity relationship model for rivers in Guangxi

水平式ADCP是目前最常用的自动化流量监测设备之一,在广西水文系统已得到了广泛应用。指标流速~断面平均流速关系率定是水平式ADCP应用中的关键技术环节。利用国际通则,结合实践经验推导出的水平式ADCP流速关系模型,在广西16处典型河流的流速关系率定中得到验证与应用,取得显著效益。该模型已逐步在区内外水文等涉水行业中推广,促进了流量监测自动化、集成化发展。

As one of the most commonly used automatic flow monitoring devices at present, horizontal ADCP is wide- ly utilized in hydrological system of Guangxi. The calibration of index flow velocity-profile average velocity relation- ship is the key technical link. By use of international general rule and combined with practice experience, the hori- zontal ADCP flow velocity relationship model was derived and has been examined and utilized in calibration of 16 typical rivers in Guangxi, rendering significant benefits. This model has been gradually popularized by water indus- tries including hydrological departments within and out of Guangxi, promoted automatic and integration develop- ment of flow monitoring.
