摘要： 本文从Palnard Conside[1954]提出的岸线演化方程出发,提出在沿岸流作用下,海湾岸线的不冲不淤点位置与海湾形态的对称性、外海破波角和输沙率有关.海湾不冲不淤点随时间向湾外迁移,曲折岸线的不冲不淤点位于它的中心,位置稳定.

关键词: 海岸线, 河口

Abstract: Under long-term action of alongshore drift,the statistical sediment movement on a coast is proved to be a linear diffusional process.An evolution equation of the coastal line can be denoted by where x,y are illustrated in Fig.I,respectey, a is a parameter dependent on the sea coast,t is time.

Key words: coastal line, estuary
