Application and Analysis of Multi-Beam Bathymeter in Ultra Shallow Water Area
When recovering the coastal shrimp and crab breeding pits,it is necessary to backfill the pits,which are generally obtained through underwater measurements to obtain the water depth value of the bottom of the pits.The traditional measurement method of manual rowing supplemented by RTK has low efficiency and large personnel investment,and the single-beam sounder has the disadvantages of narrow coverage and low measurement accuracy,which cannot meet the requirements of short,flat and fast daily surveying and mapping.The continuous development and maturity of multi-beam sounding technology has brought the possibility of improving underwater measurement methods,and after analysis,the use of multi-beam sounder has obvious effects in the measurement of ultra-shallow waters such as pit ponds,because it has the advantages of large measurement range,fast measurement speed,high accuracy and high efficiency,and is especially suitable for large-area underwater exploration.Compared with the measurement accuracy of the traditional method,it is concluded that the measurement of multi-beam sounder in ultra-shallow waters can meet the daily surveying and mapping requirements of coastal shrimp and crab breeding pits.
