Dujiangyan is a super water conservancy project more than 2,000 years ago. It was because of its existence that it created a rich abundance of land, and it has been operating continuously since 2000, but do you know what Dujiangyan works? Looking at the wisdom of the ancients from the sky is really impressive, let’s take a look at it!

First of all, Dujiangyan has a very important setting, that is, the water divider fish mouth. It divides the Minjiang River into the inner river and the outer river. The outer river is composed of natural river channels, and the inner river is a river channel dug manually. Therefore, during the dry season, most of the River water will pour into the Neijiang River, and during the flood season, the excess river water will be washed away, and the third waterway is also set up with a dump, which can play a role in sand discharge and drainage here, so here The water flow has passed through layers of water, and the special terrain can be used to guide the water flow here to the plains and corresponding water-scarce areas, so that these areas have water resources for irrigation.

What do you think of this?
