Morphological change and siltation in North Passage Deep Waterways in Yangtze Estuary, China
摘要
Abstract
Taking the North Passage of the Yangtze Estuary as a research object, based on topographic data and maintenance dredging materials of deep⁃water channel from Dec.1997 to Feb. 2013, morphological change and siltation of the North Passage Deep Waterways were analyzed. Results show:(1) there were wide range deposition in the north beach of the North Passage upside;the south beach of the North Passage downside presented widespread deposition;the bend section was focused area to silt;the channel form developed to the direction of narrow and deep;(2) siltation were large amount about 64 million m3 since the three phase 12.5 m waterway project with section and season difference;(3) siltation distribution was great different along the North Passage channel, siltation volume of middle section (H⁃O) accounts for 70%of total volume;(4) siltation was great different during flood season and dry season, siltation volume during flood season accounts for 80%above of yearly volume;(5) siltation in the south sec⁃tion was higher than the north section of about 4 million m3 to 13 million m3;(6) siltation distribution during three phase 12.5 m waterway project was different with two phase 10 m waterway project.关键词
