After more than 20 days and nights of fighting, Tianjin’s flood control and relief work has achieved initial results.
Affected by Typhoon Du Surui, since the end of July, there have been heavy rains in many places in the north, and a basin-wide flood has occurred in Haihe River. As the main "estuary" of floods in Beijing-Tianjin-Hebei region, Tianjin undertakes 75% of the flood discharge tasks in Haihe River Basin.
For Tianjin, which is low-lying and located at the end of the Nine Rivers, this is a big battle and a big test.

As long as the incoming water level is higher than the tide level, the sluice will be lifted immediately to discharge flood. He said: "One more minute of water discharge, the upstream water level may drop by one centimeter."
On August 9th, the tidal gate opened for 23 hours, setting a new high of 80.78 million cubic meters of flood discharge in a single day.

He said: "Only when the upstream and downstream cooperate can Tianjin flood more efficiently."
