本文建立了一个理论模型，对紊流孔中的水流、流速剖面、剪应力、能量耗散等进行了较为详细的描述。对紊流前缘趾部的水流条件进行了分析，结果表明，该模型与通常基于有限振幅浅水方程的描述有很大的不同。结果表明，该模型能更好地描述实际物理条件。最后，数值结果表明，该模型是如何工作的，并测试其有效性与已知属性的例子。
A theoretical model is developed giving a moderately detailed description of the flow in a turbulent bore, the velocity profiles, the shear stresses, the energy dissipation, etc. An analysis of the flow conditions at the toe of the turbulent front indicates significant differences from the usual description based on the finite-amplitude shallow-water equations, and it is shown that the present model gives a closer description of the actual physical conditions. Finally, numerical results are presented that illustrate how the model works, and test its validity on an example with known properties.
