| Abstract: | The hydrological and sediment conditions are complex and morphology is highly varied in the
Yangtze estuary. The temporal and spatial distribution of siltation is also complex in the deepwater navigation channel of the Yangtze estuary. The shallow spots can inevitably take place at the edge of the navigation channel.This paper analyzes the distribution characteristics of shallow spots at the edge of the navigation channel during the periods of 10.0 m-water-depth maintenance and 12.5 m-water-depth trial navigation, as well as the factors that influence the occurrence of shallow spots. The quality control standard of shallow spots at the edge of the deepwater navigation channel in the Yangtze estuary is proposed and adopted, which has obtained favorable application effect. |
