摘要
采用声学多普勒水流剖面仪(ADCP)对麻涌河清淤前后水下地形进行测量,并结合实时动态GPS测量技术,通过相关软件获取清淤前后河底高程,然后分别应用AutoCAD、Excel常规软件法和南方CASS6.1测绘软件法对麻涌河清淤量进行模拟计算。通过对两种计算方法的结果分析比较,表明南方CASS6.1法从计算耗时和准确度而言更具优势。
Acoustic doppler current profilers was used for surveying underwater topography of Machong river before and after dredging, combined with realtime kinematic GPS technology, acquiring river bed elevation via relevance software. Then, AutoCAD, Excel, Google Earth and South CASS6. 1 were separately applied to simulate the calculation of dredging volume of Machong river. The results show that the CASS 6.1 is with higher efficiency and more accurate.
