The fundamental reason for the annual flooding of many provinces along the Yellow River is that the upstream soil erosion is severe, resulting in silt and blockage of downstream silt. When heavy rainstorms come during the flood season, it will break through the river and cause heavy water.

If you want to cure the root cause, you naturally have to start with soil erosion in the upper reaches. However, with the level of social development power of the Ming Dynasty, this was almost impossible to accomplish, so there is only one way to control water.

In the dynasties that followed the Song Dynasty, including Xu Youzhen’s memorial, the method chosen was to “diversion and kill”. That is, to dig new tributaries of the river and divert the fierce and surged Yellow River water during the flood season, thereby reducing the pressure on the main river embankment.

The advantage of this method is that the project difficulty and project volume are small, and even the requirements for project quality are not high. It is a water control strategy that does not seek to be reliably but does not seek to be ineffective.

The disadvantages of this method are also obvious. Digging a river channel means encroaching on large areas of farmland and land, which will cause many farmers to lose the land they rely on for their livelihood, resulting in complaints from the people and their families and their families are destroyed.

In addition, digging new river tributaries is not a one-time solution. If you do not pay attention to maintenance and dredging, you will often be blocked by the mud and sand brought by the Yellow River water in a year, and the water flows across the river to flood the crops and farmland, which will expand the scope of the disaster.

Another important disadvantage is that local gentry will continue to occupy these excavated river channels to build fields.

As a result, the farmers were deprived of the river tributaries excavated from the land. After a round, the farmers' land was gone and the river was gone, and in the end only the landlord's land was left.

"Binding water to attack sand" has taken another completely different principle. Not only does it not dig new river tributaries, it blocks all the diversion rivers, allowing the Yellow River water to concentrate on a single river channel.

This will increase the velocity of the water flow in the river trough and wash away the silt silted from the riverbed. Only by clearing the silt of the Yellow River silt can we truly cut off the risk of river embankment and avoid the land of farmers being encroached on!

Of course, Chen Tao, the chief clerk of this water control plan, could have imagined that so many capable people and patriots in all dynasties could not have imagined that they could not have imagined that so many people in history had dynasties.

Why don’t they do it? The problem arises in the cost!

"Binding water to attack sand" increases the flow rate of the water flow, which is equivalent to artificially creating flood peaks to wash away mud and sand, which has extremely high requirements for the solidity of the river embankment.

Just now, Shen Yichen could step on the tofu slag on a river bank, and could it withstand the erosion of the water flow?

Don't let the water control fail at that time, it will cause greater floods to form a vast ocean. Shen Yichen may be called an eternal sin.

"Then what is the clean and yellow brush?'

Stripping water to attack sand is not a new plan, but Shen Yichen has never heard of the word "storing clear and brushing yellow". I want to hear what unique water control plan does this Yanggu County chief clerk have.

Seeing Shen Yichen constantly asking about his ideas for water control, Chen Tao at this time had completely lost the fear he had before. On the contrary, he was filled with a zeal of talking!

"Qianxian, the Yellow River has seized Qing and entered the sea several times in history. It is better for us to go the other way and lead the clear water into the yellow. With the help of the water potential of the clear water, it will impact the silt silted by the Yellow River, thereby greatly improving the effect of binding water and attacking sand!"

Qingshui is the nickname of the Huai River in the Ming Dynasty. Because compared with the turbid "yellow" water of the Yellow River, the water of the Huai River is obviously much clearer, so the Huai River is called Qingshui.

The reason why he can spend a small amount of money to do big things is very simple. Chen Yichen can guarantee that there will be no geese plucking hairs under him, and all kinds of rifts are not corruption. These money will be used in river workers and disaster victims.

But many times the plan cannot keep up with the changes. What Shen Yichen doesn't know yet is that both the water conservancy and the people's strength may be more difficult than he expected.
