If soldiers and horses enter, they may suffer a heavy setback.

Wen Bo did not explain too much to Xue Chuan. He asked them with a dark face to seriously consider the direct impact this matter might have on southwestern Liang and northwestern Huaihe.

Geography, arithmetic, engineering and other subjects are compulsory for mid-level and senior military attaches to enter the military academy for training. Xue Chuan and Wen Yuan studied them very seriously.

After the Yu River is seriously silted up at Wenbo Point and the river bed is likely to hang out of the flat land on the south bank, the subsequent impacts can also be deduced accordingly.

Once the Yu River (Yellow River) completely changes its course to the south, it is not difficult to imagine how serious the disaster will be in the areas along the Honggou and Shaying Rivers. However, in addition to the war situation in the Central Plains becoming worse and more chaotic, Huaixi will also not be immune.

will be directly and profoundly affected.

This is mainly determined by the geographical location of Yinghe Estuary to the west of Shouchun.

The Kashikou in the northern part of Shouchun is less than 70 feet wide. This extremely special terrain has seriously affected the discharge of water from the upper reaches of the Huaihe River during the summer and autumn rainy seasons. However, seven to eight years out of ten years, water will flow west of the Kishikou.

A large flood detention area is formed on both sides of the Huaihe River.

In the past ten years or so, when Xu Mingzhen was the governor of Shouzhou, he organized the military and civilians to build levees on the south bank of the Huaihe River, which is eight kilometers away and west of Shouchun City, and almost restricted the flood detention area.

In Yingzhou on the north coast.

If the Yu River takes over the Jialu River, the Shaying River diversion becomes a reality before summer, which means that the water potential in the upper reaches of Xia Shikou will expand three to five times after accommodating the water from the Yu River.

This is no longer a question of how much the flood detention area on the north bank will expand. It also directly involves whether the levee on the south bank can withstand the impact of such a large flow of water.

Once the south bank levee fails to hold up, it means that Shouzhou will become a vast ocean this summer.

With advance precautions, the loss of men and horses will be extremely limited. However, according to the resettlement plan in Shouzhou, 500,000 to 600,000 acres of cultivated land will be submerged. After the year, it is planned to start the Yanhu project in Longchi Mountain, the dredging of the Bei Feishui River, and

A series of subsequent matters to build Shouchun into an important town in the northwest of Huaihe will be delayed, and the losses in money and food will be extremely heavy, which may interrupt the current construction and development rhythm of Tangyi.

Perhaps the losses in Huaixi are still limited. The diversion of the Yu River has a more serious and tragic impact on the area currently controlled by the Liang Army in the Hehuai River. This will involve the situation in the Hehuai River becoming more complicated and chaotic. Even Emperor Zhu Yu of the Liang Dynasty did not

If it can hold on in Xu Ru and other places, it will cause the Mongol cavalry to drink their horses on the north bank of the Huaihe River. The negative impact on the war situation in Huaixi and the Central Plains will be even more frightening.

Wen Bo gathered some of the military attachés and set off from Liyang on horseback, arriving at Shouchun City before seven o'clock on the first day of the new year.

The Shaying River is currently the lifeline of the Hehuai Liang Army. Tangyi supplies reinforcements to the Hehuai Liang Army, as well as Xu Ruying, Chen and other prefectures that are suffering from severe drought. The main grain fields are distributed on both sides of the Shaying River. Zhou Daoyuan, the minister of the Liang State Ministry of Industry, arrived in Ying at the end of the year.

The prefecture inspected Yingshui River Affairs. When he received the news from Guo Duanduo from Shouchun, Zhou Daoyuan had not yet left Yingzhou.

After receiving the news, Zhou Daoyuan sent people to Xinzheng to report to Liang Emperor Zhu Yu, and he himself rushed directly to Shouchun to meet Han Qian.

Emperor Zhu Yu of the Liang Dynasty attached great importance to the management of the Yu River watercourse. After he ascended the throne, he specially set up the River Affairs Department in the Ministry of Industry. It also happened that before the sudden change in Heshuo, the Ministry of Industry of the Liang Kingdom had just organized manpower to conduct a survey on the hydrological conditions of the middle and upper reaches of the Yu River.

Survey, thus having the latest data that Han Qian urgently needs.

Due to the special terrain, the water regime in the Xingyang River section is extremely complex, and the siltation conditions in the river vary from light to heavy. As the Minister of Industry most valued by Emperor Liang, Zhou Daoyuan did not need to transfer data from Bianjing, and he was familiar with all kinds of data.

Familiar with it.

Before the news came from Tangyi, Emperor Zhu Yu of the Liang Dynasty had just sent someone over to summon him back to Xinzheng in order to ask him to assess the possible impact of the dike excavation in Xingyang.

The mouth of the river chosen by the rebels to dig the embankment was indeed the most heavily silted section of the river. Even if the river bed did not hang out of the ground, it was almost there.

And if, as Han Qian expected, all this is a carefully calculated strategy by Liang Shixiong and the Mongols, they only need to recruit 30,000 to 40,000 soldiers and civilians, and it is relatively easy to build a water dam slightly downstream, and it is very likely to successfully force the Yu River to flow.

Water flows southward from the Jialu River and the Shaying River into the Huaihe River and into the sea...

After confirming this information, Han Qian ordered the main soldiers and horses of the Second Town Army to assemble in Shouchun, and ordered the Youshenwu Army to return home to recruit new soldiers, and all went to Shouchun to assemble for training.

The state issued a military order to recruit 10,000 young and strong civilian men to gather in Shouchun.

A few days later, Emperor Zhu Yu of the Liang Dynasty sent news from Xinzheng, confirming that the Mongols had established an additional camp on the north and south banks of Zhaotang Dike downstream of where the Weizhou rebels were digging the embankment.

Zhaotang Embankment in Wuzhi County is located on the west side of the Jialu River connecting to the Yu River gate. The river bed is more seriously silted. It is also an excellent place to build a river dam downstream of the embankment breach.

At present, the Yu River is still frozen, and there is still about a month and a half of ice-free period. The water flowing under the ice is also very shallow. Although no further actions by the Weizhou rebels and the Mongol people can be seen for the time being, the entire

Since the plan was determined to be carried out jointly by the Weizhou rebels and the Mongols, it was unrealistic for them to hastily send troops to attack Xingyang City at this time. It is not an exaggeration to predict the worst-case development of the situation.

According to the request of Emperor Zhu Yu of the Liang Dynasty, Han Qian immediately sent from Shouchun 120,000 shi of brown rice, 3,000 dans of rock salt, 30,000 dans of fine iron, 5,000 armors, 2,000 fine steel crossbows, and 200 bed crossbows.

As well as 10,000 bundles of iron arrows and other supplies, the prefectures and counties controlled by the Hehuai Liang Army organized manpower to transport them to Xuzhou by land before the Hehuai River warmed up and the ice melted, in order to avoid that the floods would wash down in the future and the transportation capacity would not be able to keep up.

.

On January 20th, in addition to the 10,000 elites of the Second Town Army, 2,000 generals of the navy, and 1,000 cavalry guards in Shouzhou, the newly formed Youshenwu Army was released for nearly half a year's family reunion holiday.

Twelve thousand generals, as well as 40,000 young men recruited from the outer prefectures and 20,000 young men recruited from the three counties of Huoqiu, Shouchun, and Fengtai, all assembled in Shouzhou with unimaginable efficiency.

.

Han Qian signed a military order on the 21st of the first month of the lunar month, officially setting up a government in Tangyi. In addition to the first, second, and third town armies, Tangyi water army, and guard cavalry, a fourth town army was added, and Wen Bo was appointed.

As the capital commander, Tan Yuliang is the deputy capital commander.

On the day the Fourth Town Army was formed, the generals did not immediately issue soldiers, armor, and weapons. Instead, they directly distributed a large number of shovels and shoulder burdens. The 60,000 young men and women who were temporarily recruited were also temporarily incorporated into the Fourth Town Army.

.

The current task of the Fourth Town Army is, first of all, to do its best to reinforce the embankment on the south bank of the Huaihe River west of Bagong Mountain before May.

Ji Xiyao and the engineering officers and engineers from the Engineering Institute who specialize in water conservancy and river affairs have conducted new emergency mapping of the terrain around Shouchun City in the past half month.

After obtaining first-hand data, Han Qian decided to designate the lower reaches of the Beifeishui River, Wabudang located east of Shouchun City, and the surrounding shallow area with a total area of ​​3,000 to 4,000 square miles as a specific flood storage area.

The few households in this area will be relocated and resettled.

However, the flood detention area is on the west side of Shouchun City and may extend westward to Huoqiu this year, but the tile dump is on the east side of Shouchun City. A road three to four meters deep and two meters wide will be dug between the two areas.

It is impossible for 50,000 to 60,000 people to complete a three-hundred-meter, fifty-mile-long flood-carrying river in three to four months.

Then we can only draw a relatively open, low-lying flood channel between the west embankment of Shouchun City and Wabu Dang.

What needs to be done now is not only to build shallow embankments on both sides of the flood channel to protect the irrigation area and Shouchun City behind it, but more importantly, to dig out all terrain obstacles in the flood channel that are not conducive to the rapid discharge of flood water.

This will ensure that a large area of ​​flood detention will be formed between Shouchun and Huoqiu, and the flood can be directed to Wabu Dang through the flood channel as quickly as possible, thus greatly reducing the impact on farming.

The Longchishan Weir Lake also needs to be built according to the original plan, but a new channel needs to be urgently excavated between the Longchishan Weir Lake and the Bei Feishui River so that the stream water in the Longchi Mountain area can be directed north before the rainy season.
