Abstract

Abstract

The evolution of large tidal flat in estuaries is related to smooth navigation, ecological protection and safety of offshore engineering. It is also a hot topic in geomorphology and engineering. A single beam bathymetric system was used to monitor the Chongming Eastern Beach in the Changjiang River Estuary. The scouring and silting pattern was analyzed based on the environmental factors in recent years. The results are as follows: (1) Chongming Eastern Beach and the north inlet of the North Channel are mainly deposited in 2011−2017 years, and the northern sand terrain of the North Channel is greater than that of the Chongming Eastern Beach, and the central part of the North Branch of the North Channel is −2 m deep in the central area, which is a silt up situation, and the envelope area of the −5 m contour in the study area is basically stable, and the whole pattern is "long height and no growth". (2) Marine sediment is the main source of silting, and the main circulation of the two large circulation formed by the time and space of the rising and falling of the three branches in the study area is the main reason. (3) The reclamation project in the south of the Chongming Eastern Beach and the North Branch is the main factor causing the North Branch atrophy and the silt of the Chongming Eastern Beach, and the ebb tidal diversion of the cross sand channel. As a result, the curvature of the North Channel is a key factor leading to the deposition of North Sand in the North Channel. The siltation of the two beaches directly squeezed the development of the North Branch of the North Channel, which was the main cause of its transition from the tidal trough to the ebb trough, and the siltation situation in the North Branch of the North Channel may cause the next two large sand bodies.
