December 15-16, 1992, chaired by the Department of Science and Technology of the Ministry of Communications, held in Tianjin, “downstream of the dam river cut and its mathematical model,” the results of the identification of acceptance. After listening to the report on the achievement of the project and after careful discussion, the Commission of Accreditation and Acceptance agreed that the subject of the study was to study the characteristics of the process of undercutting downstream of the dam, especially the downstream channel after the construction of the Three Gorges Project and its impact on shipping. Clearly, it is of great significance to the construction of the Three Gorges Project and its research achievements are as follows
