broad crested weir

Using boundary layer and critical depth of flow theories, the hydraulic calculations are carries out for streamlined broad-crested weir. The method open a new way in the calculation of the broad-crested weir.

采用边界层理论和临界水深理论，实现了流线形宽顶堰流的水力计算，此方法为宽顶堰流流量的计算开辟了一条新途径。

The method was adapt broad crested weir theory derivation to calculation flood rate of discharge and conjecture design rate of discharge through field investigate information of bridge.

该计算方法是通过实地调查桥前水深等资料，采用严密的宽顶堰理论推导，求得洪水流量，进而推求设计流量。

The text submit calculation flood rate of discharge of small bridge with broad crested weir thory.

提出用宽顶堰理论检验法计算小桥涵洪水流量。
