长江潮区界上界河槽浅层沉积结构探测研究
Sub-bottom Sedimentary Structures Research and Detection at the Upper of Tidal Limit in the Chang Jiang River
摘要
Abstract
Sedimentary structure is one of the important methods on the understanding of the migration of river.However,as the momentous interface of the material and energy transportation,there has never been a report of the sub-bottom sedimentary structure research at the upper of the tidal limit in the Chang Jiang River." Full coverage" detection by a sub-bottom profiler is made at the upper of the tidal limit in the Chang Jiang River from July 2015 to August.The results show that a lot of symmetry-to-downstream dunes develop at the upper of the tidal limit in the Chang Jiang River (Chongwenzhou tail).In contrast,dunes develop on both sides of the downstream waterway of the Chongwenzhou tail with a smaller scale in the height and spacing.The sub-bottom sedimentary structure shows that there are layers developed in part of the Guichi waterway under the riverbed.关键词
