Research for temporal and spatial distribution of ship accidents in the fluctuating backwater area of three gorges reservoir region

Abstract

The Yangtze River is the main artery of the inland water transportation of China, connecting the resource-rich southwest hinterland, the Central China region and the economically prosperous southeast coast of East China. Chongqing, located in the fluctuating backwater of the Three Gorges Project, is the mainstream of the Yangtze River and the Jialing River. It is not only the industrial and commercial center of China but also the most abundant water and intermodal inland hub and material distribution center in the southwest. Based on the ten years of statistical data of ship accidents from 2009 to 2018 of the Chongqing Maritime Safety Administration (MSA), this paper takes the navigation section of the fluctuating backwater area of the Three Gorges Reservoir as the research object, and comprehensively uses statistical analysis, comparative analysis, and data visualization methods. The temporal and spatial distribution characteristics of ship accidents in the fluctuating backwater area and the economic losses in this area are studied. The research results are helpful for strengthening maritime management, improving navigation conditions, and reducing water traffic accidents in the Three Gorges Reservoir area and other similar reservoir areas all over the world. In addition, the research gives detailed guidance for stakeholders and mangers for the prevention of water traffic accidents.
