Application of multi-beam sonar technology in reservoir capacity measurement
To accurately monitor the dynamic changes in the reservoir capacity of the Foziling,Mozitan,and Bailianya reser-voirs since their construction,satellite positioning technology was used to precisely obtain control point coordinates.An airborne lidar and mul-tibeam sonar system were employed to conduct full coverage measurements of both the water surface and under-water topography.The results showed that the three reservoirs were affected by sediment accumulation and other factors,and the current storage capacity was significantly reduced compared with the approved value of storage capacity.In the operation and management of reservoirs,it was necessary to carry out dredging work in an orderly manner to ensure the normal perfor-mance of its comprehensive functions such as flood control,irrigation,water supply and ecological maintenance.The measure-ment data of this technology were accurate and comprehensive,and the measurement results can provide reference for reservoir safety assessment and flood control operation.
