The researchers studied how underground water levels respond to changes in river water levels near the Yangtze River in Wuhan, China. They created a new model that accurately predicts how the groundwater levels in the area change over time. By analyzing data from 2017 to 2019, they found that their model was much more accurate than previous ones, with only an 8% prediction error compared to 26%. This improved model can help engineers better plan for construction projects near rivers, especially in the Yangtze River's first terrace.
