黄河口“烂泥”波浪特性的分析

ANALYSES ON WAVE CHARACTERISTICS AT MUDDY SEDIMENT OF YELLOW RIVER ESTUARY

根据１９９１年１１月２３～２４日现场波浪测量资料，分析了黄河口“烂泥”的 消波效应。结果表明，波浪传至“烂泥”后波高和周期均有明显减小，波浪频谱也有 较大的变化，“烂泥”是一个天然的“避风港”。

Based on the field measured wave data at Muddy Sediment and Yellow Harbour in Nov. 23-24, l991, wave characteristics and wave spectra have analysed. Te analyses shows: since waves propagate into Muddy Sediment, is a clear reduction of wave heigts and wave periods (thus wave lenghts) there is also a clear reduction of 0-moments of wave spectrum and spectral peak values, but there is a clear increace of wave spectral peak frequencies, and there is a clear variation of wave spectral shape. So the Muddy Sediment is nutural haven.
