Abstract

The invention discloses an in-situ observation system for a seabed sand wave migration process, which comprises a set of sand wave sonar system, and is characterized in that the sand wave sonar system is arranged at a selected seabed target position to scan the same seabed area; the sand wave sonar system comprises a sonar assembly, a self-weight anchor, a support and a mooring rope; the sonar assembly is connected with the support, and the support is connected with the self-weight anchor and the cable; and the mooring rope is connected with a floating ball and a buoy from top to bottom. The in-situ observation system for the seabed sand wave migration process is simple and reasonable in structure, convenient to install and use, wide in application range and high in anti-interference capacity. Fixed-point and in-situ seabed sand wave migration observation can be realized, short-time-interval and long-time-period continuous observation can also be realized, and the system is of great significance to research of a seabed sand wave migration rule. The system is worthy of popularization and use.

Description

technical field [0001] The invention is applied in the technical field of marine geological environment detection, is a sharp tool for studying the law of seabed sand wave migration, and has great significance for studying the change of seabed geological environment. Background technique [0002] Sand wave is a deformed micro-geomorphology formed by seabed sediments under the shear action of the bottom current. Sand wave is also a small-scale landform that can cause geological disasters under the influence of external conditions. an important item. [0003] In the prior art, the observation of the seabed sand wave migration process generally adopts irregular measurement and observation by shipborne sonar, and the comparison and analysis of the seabed sand wave sonar images obtained by different periods of observation is carried out to study the law of seabed sand wave movement in the target area. The law of wave migration is used to study and analyze hydrodynamic conditions...
