1 浮标在流量测验中的作用《水文测验规范》规定,浮标法流量测验是水文测验的基本方法之一。在山区,由于水流涨落较快,其流速较大,其它测流手段一般无法正常实施,浮标成了流量施测的主要方法。即使是在平原河道,如果出现特大洪水超出了水文缆道的测流设计能力,水文缆道无法使用,也必须使用浮标法施测流量。另外,在水文缆道出现故障无法正常使用时,浮标测流也是一种行之
1 buoy role in the flow test “Hydrological test specification” provides that the buoy method flow test hydrological test is one of the basic methods. In mountainous areas, because of the rapid fluctuation of water flow and its large flow rate, other means of flow measurement are generally unable to be implemented normally. The buoy has become the main method of flow measurement. Even in plain rivers, if a catastrophic flood occurs beyond the hydrographic cable’s hydrodynamic design capability, the hydrological cableway can not be used and the buoy method must be used to measure the flow rate. In addition, in the hydrological cable fault can not be used normally, the buoy current measurement is also a
