充分利用波浪要素（波高、周期）玫瑰图推算沿岸输沙率和对设计波浪进行验证。

This paper proves the calculation of long-shore sediment discharge rates and design waves by making full use of the roses of wave factors (wave height, period).

用什么特征波要素来推求破波要素以计算出沿岸输沙率，尚有一些问题业未澄清。

Using which of the deep water characteristics to compute the breaking wave characteristics and then the longshore transport rate is a problem yet not being clarified.
