| 摘 要： | 利用Sea Bat 7125多波束测深系统,对长江河口南港河段进行了沙波的高分辨率观测研究。结果表明:南港河段沙波发育广泛。统计的沙波中,最小波高0.12m,最大波高达3.12m;最小波长为3.12m,最大波长为127.89m。其中,南港上段、南港中段主航道、南港下段沙波陡坡有向海倾斜的趋势,而南港中段主航道南侧沙波陡坡有向陆倾斜的趋势。

| Abstract: | High resolution observations of sand waves in the South Channel is carried out by using Seabat712 5.multibeam sounding system.The results indicate that sand waves widely developed in the South Channel of theYangtze Estuary.Statistics show that minimum wave height is only 0.1 2.m while maximum wave height is 3.1 2.m,andminimum wave length is 3.1 2.m while maximum wave length is 127.8 9.m.The sand wave slopes have a tendency to tiltto the sea in the upper reach,lower reach and middle-reach main channel of the South Channel,however,the sandwave slopehas a tendency to tilt to the land in the south of the middle-reach main channel of the South Channel. |
