广西北海涠洲岛典型岸滩剖面短期冲淤变化特征
Short-term shore change characteristics of erosion and deposi-tion on Weizhou Island in Beihai, Guangxi Province
摘要
Abstract
Based on data of beach profiles and sediment grain acquired from Weizhou Island in December 2012, July 2013, and December 2013, the short-term shore change characteristics of erosion and deposition on Weizhou Island were analyzed from 2012 to 2013. Results showed the following: (1) From December 2012 to July 2013, most of the sections of the island had eroded and that the most seriously eroded area was the middle beach due to the effect of a tropical storm; (2) From December 2012 to December 2013, eroded sections occurred mainly in the southeast, southwest and on the low beach of the northwest, moreover, silting sections appeared in the north and upper part of the northwest; (3) Results of a mean particle diameter analysis showed that there were coarser sedi-ments on the high beach than on the low beach, illustrating that the high beach had a relatively high hydrodynamic environment. Changes in coastal sediments were consistent with scouring and silting changes of each beach profile. During a short time period, the factors affecting scouring and silting changes on Weizhou Island were waves, tides, storm surges, human activities, etc.关键词
