The article explores different ways to control the flow of water in large gates in water transportation channels. By studying a specific gate in the South-North Water Transfer Midline Project, researchers found that adjusting the flow in stages can help manage water levels more effectively. For example, they recommend limiting the increase in flow to 16m3/s in one hour and 20m3/s in two hours to minimize the impact on the channel. This approach can help maintain a stable water level and reduce disruptions in the water transportation system.
