Beach morphodynamic state is one of the important contents to understand beach processes and land-ocean interac-
tion. Few studies on geomorphology and deposit for sandy beaches in response to strong-tidal action in China have ever been
conducted. Based on the measured profile change and associated depositions of Yintan Beach in March, 2010, deposition cha-
racteristics of strong-tidal beach profile in response to externally-driven actions were analyzed. The results show that: 1) It is
of simple geomorphologic composition for Yintan Beach, and its geomorphologic state is attributed to one of the dissipated
types. 2) Deposition of Yintan Beach is a kind of sand with main compositions of fine sand and medium sand. The sorting of
depositions is relatively well. In addition, the percentage of both medium sand and the median size in deposition gradually
decreased from land to sea, and the percentage of the super-fine sand in depositions from land to sea gradually increased. 3)
Depositions along the transverse profile for Yintan Beach can be divided into three types: backshore cell, beachface, and in-
shore part. Sediments in the backshore part consist of mainly saltation load under the control of wind action. Sediments in the
beachface are of bilateral movement resulted from swash actions driven by broken waves. However, sediments in the inshore
part consist of mainly siltation load with the determination of combination of tidal current and wave.
