Application of multibeam sounding system in siltation calculation of navigation channel

Abstract:

Influenced by the storm surge of the Yellow Sea and the Bohai Sea on March 18, 2015,the navigation channel of Sendamei Port in Weifang City was silted up. In order to calculate the sediment volume, three sections of the channel with different distances from the coast and different degree of siltation were selected based on the tonner and length of the channel to conduct undersea topographic survey with the multibeam sounding system. Compared with the channel terrain data before the storm surge, the sediment volume of the three sections of the channel after being affected by the storm surge were figured out and the sediment volume of the whole channel was calculated, and the loss brought by the storm surge to the construction unit of the channel were assessed.

Keywords: multibeam sounding system   channel survey   siltation calculation
