摘　　要：在缺少海洋水文观测资料的情况下,利用风浪后报推算设计波浪参数是工程上常用的方法。探究了我国现行《海港水文规范》中"深水风浪要素计算图解法"诺谟图存在的缺陷,并与美国工兵团新版《海岸工程手册》的波浪图解后报方法进行了比较分析,所得结论对于我国海岸与近海工程的波浪后报计算具有重要参考意义。It is a common method to estimate the design wave parameters by wind wave hindcasting method in the case that there is no observed hydrologic data at engineering site.This paper discusses the defect in the nomogram for calculating deep-sea wind wave factors in Chinese Code of Hydrology for Sea Harbor,and analyzes it comparatively with wind wave hindcasting method in a new edition of Coastal Engineering Manual（CEM） by U.S.Army Corps of Engineers.The conclusions will be references to hindcast wind wave in higher accuracy for coastal and offshore engineering practice in China.
