Further, a coupling model of hydrodynamic model and water quality model was developed and it can be applied to simulate the water environment of a tidal river network controlled by gates.

But the barrier will require laborious circumnavigation by villagers, through roads, checkpoints and army-controlled entrance gates, turning a five-minute journey into a five-hour one.
