22、度而定根据渠道深度而定,高出上游水位高出上游水位0.1-0.2cm,一般可采用一般可采用1.00米。量水槽上下游护底长都为槽底高米。量水槽上下游护底长都为槽底高H的函数的函数:上游护底上游护底L=4H;下游护底下游护底L=(6-8)H;同时,由于量水槽内流速较大,喉道中水面的波动也很大,直接在槽中测定水位同时,由于量水槽内流速较大,喉道中水面的波动也很大,直接在槽中测定水位有困难。因此,在槽壁设置后观测井,安量测水尺。井底比槽槛要低有困难。因此,在槽壁设置后观测井,安量测水尺。井底比槽槛要低20-25cm,测井与量水槽可用平置的金属管或混凝土管连接,管子的中心线应高出槽底测井与量水槽可用平置的
23、金属管或混凝土管连接,管子的中心线应高出槽底3cm,上游水尺位于喉道上游距喉道首端,上游水尺位于喉道上游距喉道首端(2/3)处,下游水尺位于喉道末端以上处,下游水尺位于喉道末端以上5cm的的槽壁处。上下游水尺零点与槽底高要齐平槽壁处。上下游水尺零点与槽底高要齐平,观测井要无漏水现象观测井要无漏水现象,井中经常理泥沙井中经常理泥沙,井上加盖井上加盖,避免杂物入内。避免杂物入内。设置在雨水花园内的巴歇尔槽(Parshall flume)Discharge monitoring of Natural drainage systemMeasurementandexperimentalanalysis
