Abstract

Objectives of the study

Based on hydrological observation data of the upstream and downstream control stations of the cutoff river section, this paper analyzes the characteristics of water and sediment transport and ratio variation in such three stages as before, during, and after the natural cutoff of Shatanzi, and studies how the water and sediment conditions affect the formation and development of the natural cutoff at Jingjiang River.
