With the traditional dynamic evolution model of the seabed terrain of the dumping area, the gradual evolution process of the seabed dumping area terrain can be analyzed, but for the long-term evolution analysis process, there are some problems such as low analysis efficiency and high uncertain factors. To address this problem, dynamic model of long-term evolution of seabed terrain of dumping area based on side-scan sonar detection technology is designed in this paper. XTF embedding technique is used to embed the seabed side-scan sonar detection. The environment dynamic model is built with Windows multi thread mechanism combined with open GL Technology. The quantitative data of the evolution of the dumping area and the time quantitative data of the dumping area are calculated. The dynamic model of long-term evolution of seabed terrain of dumping area is built. Experimental results show that, compared with the traditional model, the analysis efficiency of the proposed dynamic model is increased by 60.48%, and the uncertainty is reduced by 71.23%.
