潮汐河口泥沙物理模型设计方法

潮汐河口水流系一典型的非恒定往复流，水沙运动、泥沙模型的设计远较河流模型复杂，许多问题尚无定论。本文论述了潮汐河口各类泥沙模型的相似律，指出了各类泥沙模型选沙的主要原则和时间变态的处理方法。

Design of Physical Sedimentation Model for Tidal Estuaries

The flow in tidal estuary is characterized by typical usteady reciprocating flow. The state of water flow and sediment movement and thus the disign of sedimentation model for the tidal estuary are much more complianted than that for the river. This article discussed the similarity criterion of the various sedimentation models for the tidal estuary and suggested the main selection principles of the model sand and the methods dealt with the time distortion for the various sedimentation models.
