| 摘 要： | 概述了铜鼓航道地理位置及水流泥沙条件。根据2008—2009年铜鼓航道5次水下地形测量资料,结合铜鼓海区水文泥沙环境,从航道沿程水深变化、航道冲淤分布、航道回淤量和断面形态变化4个方面,分析了航道的时空冲淤分布特点,并计算了铜鼓航道的年回淤量和平均年淤积强度。得到如下结论:铜鼓航道年平均回淤量为573万m3,平均年淤强为0.82 m,并且回淤呈现"洪季多淤、枯季少淤"和"主槽回淤较多、边坡回淤较少"的特点。

| Abstract: | The location and current & sediment conditions of Tonggu channel are described.According to the topographic survey data between 2008 and 2009,combining with the water and sediment environment in Tonggu sea,and from four aspects including the water depth's change along the channel,scouring-siltation distribution,siltation volume and shape's change of the cross section,this paper analyzes the temporal and spatial distribution of scouring-siltation in the channel,and calculates the annual quantity of back-silt... |
