The study looked at how water is taken from the Yangtze River to the Hanjiang River. By studying the flow of the river and doing experiments, the researchers learned about the speed and patterns of the water in the diversion canal. They also looked at how energy is lost at the entrance and how to remove sediment and snails from the water. The results showed that the river didn't change much at first, which is good for the project. These findings can help engineers design similar projects in the future.
