- Regularly clean up the sediments in the structures, remove algae and freshwater mussels attached to the surface, and apply roughness-reducing materials if necessary.
- Modify the shapes of the inlet and outlet structures of the crossing water-conveyance structure with undesirable flow regimes.
- Dredge and expand the drainage structures on the left bank with a high flood risk, raise the levees at the inlet and outlet, and set up grit chambers upstream.
- Explore the option of adding water-conveyance channels in the case that the existing crossing water-conveyance structures cannot be modified.
- Add automatic monitoring sections and advanced monitoring equipment to improve the intelligent sensing and precise control ability of the Main Canal.
- Increase the frequency of daily inspections during periods of water conveyance with a high flow rate and periods when rainstorms, floods, and geological disasters likely occur.
- Check the margin of safety of the structures under long-term water conveyance with a high flow rate and take structural strengthening measures if necessary.
- Check the aeration conditions of the water conveyance with a high flow rate in the underdrains and increase the number of aeration facilities if necessary.
- Take engineering and management measures to reduce the roughness of the canal and mitigate the impact on its flow capacity due to damming at the outlet of the structure.
