江河风浪计算中的一些问题

讨论了江河堤防设计中波浪要素计算的一些问题，如计算风速选取，风区长度确定，波高统计分布等。基于实测风浪资料验证分析后认为：目前常用的计算方法，用于计算风向大致垂直于水流方向时是可行的；但当计算风向与水流方向大致平行时，计算结果误差甚大。

Some Problems in the Calculation of Wind Waves

This paper discusses some problems in the calculation of wave factors when designing riverembankments, such as the selection of calculated wind velocity, the setting of fetch length andthe statistics distribution of wave height.After verification based on observed data of wind waveand through analysis, it is showed that currently used calculation methods are suitable when winddirection is vertical to the direction of water flow. But the calculation results are not accuratewhen wind direction is parallel to the diretion of water flow.
