Abstract
Before and after the flood season,the potential of Naban Reservoir will change greatly,and the slope is prone to collapse and siltation of the reservoir bed,so the reservoir management department must monitor the chang-es in the reservoir.It is difficult to achieve high bathymetry accuracy and the processing efficiency is low by relative-ly single traditional reservoir monitoring methods such as single-beam measurement.In order to better manage the reservoir,bathymetry system is used to survey the underwater topographic map for the reservoir,the underwater point cloud of a large area of the reservoir is measured and collected.Based on the accurate measuring data,the un-derwater topography and siltation of the reservoir are depicted without omission by use of CAD.Analysis is made on the underwater topographic map,three-dimensional modeling,fixed profile and alluvial situation of various scales.The monitoring provides a large amount of basic data for reservoir management,and the results of analysis can fully reflect the law and trend of reservoir topographic changes,which improve the technology and level of reservoir man-agement.关键词
