| 摘要: |
| 本文分析了杭州湾北岸张家厍潮滩450个测波记录,讨论了潮滩带波浪特征、波能衰减及波浪的统计分布;发现破碎波波高同水深间的比值γ比“常规”破波临界值(0.78)小得多,波能快速衰减;波高服从瑞利分布,周期及波高与周期的联合分布同理论分布偏差较大。 |

| CHARACTERISTICS AND STATISTICAL DISTRIBUTIONS OF WAVES ON A MUDDY FLAT, NORTHERN COAST OF HANGZHOU BAY |
|
|
| Abstract: |
| The 450 wave records on tidal flats at Zhangjiashe, northern coast of Hangzhou Bay, are analysed in this paper. The wave characteristics, transformation of wave energy and statistical distribution of waves are discussed. The critical values of wave breaking, r(r=Hb/hb), are much smaller than the "conventional" values. The wave energy decays rapidly. The wave height corrdlates well with the Rayleigh distribution. The distribution of wave periods and the joint distribution of wave heights and periods, deviates, however, from the theoretical distribution. |
