The Yellow River delta in China has been changing a lot over the years due to sediment, river movements, and human activities. Scientists studied how the delta channels adjust after river changes. They found that after each river shift, the channels moved towards the sea at slower rates and the slopes decreased over time. A model was created to describe these changes in the channels. By using this model, they could predict water levels at different points along the delta. This method could help predict how the delta will change in the future.
