第5代多波束测深系统在水库库容测量中的应用

Application of the 5th generation multi- beam depth- sounding system in reservoir storage survey

传统测绘技术获取的库容数据已经难以满足当前水库精细化管理的要求,可采用多波束测深系统获取高分辨率水下地形信息,通过计算处理获取满足管理需要的库容数据。主要研究使用第5代多波束测深系统进行水库水下地形测量及相关数据的处理方法和流程,并基于DEM法,采用Arc Map计算了某水库的库容-高程关系,绘制了高程-库容关系图。测试结果表明,该方法在水库库容测量和计算中具有广阔应用前景。

Since the traditional survey technology is difficult to meet the requirement of fine management of reservoir,the multi- beam depth- sounding system can be used to achieve high resolution data through computer processing,so the reservoir storage data that meets the fine management requirement could be obtained. The underwater topography survey by the 5th generation multi- beam depth- sounding system is studied,and the processing method and procedure are introduced. The relationship of reservoir storage versus elevation is analyzed by Arc Map based on DEM,and the curve of reservoir storage versus elevation is drafted. The result shows that this method can be widely used in reservoir capacity survey.
