一、前言在规划设计防洪工程中,需要考虑在洪泛区域内产生的波浪的预报问题。现存的预报风生波的方法(1)是基于低糙率情况导得的方程。当风暴生波穿越具有植被的浅滩洪泛区后,将产生较大的摩擦应力,因此必须估算其波高和周期。Camfield(2,3)已经扩展了小水深情况下的预报曲线,并提出了一些估算技术的建议。 I. Introduction In the planning and design of flood control projects, the problem of forecasting of waves generated in floodplains needs to be considered. The existing method of forecasting wind wave (1) is based on the equation derived from the low roughness. When a storm wave passes through a bank floodplain with vegetation, a large frictional stress will be generated, so its wave height and period must be estimated. Camfield (2, 3) has extended the prediction curve for small water depths and has put forward some suggestions for estimation techniques.
