What is a "flood storage area"? What does it do?

The flood storage area is a type of flood diversion area that performs flood control functions. It refers to an area used to temporarily store excess floods discharged from the river section, and then discharge to the outside of the area when the flood control conditions permit.

Function:

1. It can effectively solve the problem of river siltation, restore and expand the floodway discharge, and promote the development of local shipping after the river is deepened.

2. Significantly improve the traffic and flood control conditions in the flood storage area, increase the storage capacity, provide irrigation water for people on both sides of the floodway, conserve underground water resources, and improve the local ecological environment.

Extended information:

Flood discharge will undoubtedly bring huge losses to the people in the flood storage area. However, today with such perfect infrastructure, we still have to use this method to reduce Total flood damage.

This has a lot to do with the characteristics of floods. When Dayu controlled the floods, people understood that it was better to drain the water than to block it. Water cannot be blocked. Dams can block it for a while, and reservoirs can be diverted. But we cannot build dams to the sky or dig reservoirs into the sea, so there will always be floods that cannot be stopped or diverted by dams and reservoirs. Flood discharge is the only real solution to the problem of flood control.
