The Water Diversion from Han River to Wei River Project aims to address water shortages in the Guanzhong Area of Shannxi Province. By analyzing water demand and usage patterns, researchers found that a regulation project is needed to coordinate water supply and use effectively. The study looked at water use over a ten-day period from 1955 to 2007, focusing on domestic and production water use. It was discovered that additional measures are necessary to ensure efficient water management in the benefited areas.
