Yuzhou Island, almost every time he comes to Yuzhou Island, Zhu Mingzhong can feel the changes here, at this time Yuzhou Island is not only the base camp of the navy, but also the most important port in Jiangbei.

The strait between Haizhou and Yuzhou Island, which is only a few miles wide, forms a large typhoon shelter, and the existence of Yuzhou Island blocks the wind and waves at sea, even if there is a typhoon blowing in the open sea, it is also a calm place.

And the Qishan Mountain in Haizhou and the Yuzhou Mountain in Yuzhou Island, the forts on the two mountains are guarding this harbor.

"Who would have thought that there would be such a natural harbor in Jiangbei!" Standing on the fort of Yuzhou Mountain, staring at the yellow strait, Zhu Mingzhong sighed that after hundreds of years, northern Jiangsu has been suffering from the lack of a good port, which restricts the development of northern Jiangsu.

But who would have thought that in this era, northern Jiangsu has such a natural harbor. At present, two ports have developed on both sides of the strait, the Haizhou side is the civilian port, which is specially used to berth merchant ships of various countries, and the port on Yuzhou Island is a military port, which is the home port of the loyal and righteous army fleet.

"King, I'm afraid that sooner or later, this port will have to be moved, and it must be ......" Compared with the king's sigh, Wang Anmin, as the admiral of the fleet, looked a little dull.

"Oh, why is that?" Zhu Mingzhong looked at Wang Anmin with some puzzlement,

"My lord, do you see the sea in this strait? What color is it? Pointing to the strait, he said.

"Yellow?" Isn't the water of the Yellow Sea itself yellow?

"King, out of Yuzhou to the south less than two hundred miles, is the mouth of the Yellow River, the Yellow River sediment is so much, the world is rare, the Yellow River huge amount of sediment at the mouth of the river poured into the coastal zone of Jiangbei, so that the coastline of Jiangbei silted up to the sea, and there are many sediment carried by the wandering impact to Haizhou, and the formation of an underwater sand bar between the strait, over time, it will lead to the siltation of the port, it has been recorded in the history books, the depth of Haizhou in the Tang Dynasty is more than ten zhang, and today's deepest is only a few zhang deep, over time, this strait must be full of quicksand, when the time comes, Naturally, this port is unusable. Listening to the narration, Zhu Mingzhong's mind immediately thought of the Yellow River to seize Huai!

In the history of thousands of years, the coastline of Jiangbei is extremely stable, and the sand banks along the coast are developed normally, but since the 12th century after the Yellow River seized the sand, the coast of northern Jiangsu is no longer as stable as it was then, although a huge amount of sediment has been deposited on a large amount of land, but it has brought a nearly devastating blow to the coast of Jiangbei, so that in the long coastline of northern Jiangsu in later generations, there is no good port, and there are almost no real coastal cities, and even the so-called sedimentary land, if it were not for the construction of a large number of protective dams, Its shores are also eroded by the waves.

Erosion ...... Thinking of an article he had read, Zhu Mingzhong's eyes suddenly lit up, looked in the direction of the south, the Yellow River, and then said.

"The Yellow River has been taking Huai for hundreds of years, it can be said that it is a victim of one party, not to mention others, only the sediment backflow leads to the elevation of the Huai River bed, which leads to the Huai River basin from the land of fish and rice of the year, and becomes a place of frequent drought and flood this year, so that every year Jiangbei suffers from the suffering of relief along the Huai, since Emperor Gao, my emperor Ming for more than two hundred years, although the Huanghuai River has been painstakingly managed, but has not been able to fundamentally solve the problem, there is no outlet to the Huai River is still the victim of the party, millions of people on both sides of the Huai River have suffered from floods and droughts...... "As the ruler of Jiangbei, Zhu Mingzhong naturally knows where Jiangbei's weakness is, that is, the Huai River!

The Huai River is a harmful river, nine floods in ten years, floods on both sides of the river, more than 200 years of people are displaced, all because of floods, and the reason why the floods continue is precisely because the Huai River has no outlet to the sea, and even the big lake in the north of the river - Hongze Lake, is also a word out of the reason for its formation, because of the flood, and this flood is the Huai River water that cannot flow.

From the end of the Yuan Dynasty to the 20th century, in the past 700 years, all dynasties wanted to fundamentally solve the problem of the Huai River, and the problem of solving the Huai River was very simple, one is that the Yellow River returns to the old river in the north, and the other is that the Huai River flows into the sea.

From the Xianfeng period of the Yellow River north embankment burst, back to the north of the old river into the Bohai Sea, since then, the Huai River into the sea has become the choice to solve the Huai River for the harmful party.

But limited by the times, in the age of manpower

After all, tens of billions of cubic meters of earthwork or dredging, relying on manpower is almost an impossible task, and even after the 21st century, its technical conditions and government financial resources can support this project, even so, it is only a will

"The Huai River flows into the sea" became

"Led into the sea" and

The two projects of "leading the Huai River into the river" have reduced the amount of work by more than 70%, but even so, according to the plan, it will take more than ten years to complete in stages.

In particular, you can imagine the difficulty of this project. The Huai River flows into the sea! In the era of manpower, it is an impossible task, but it does not mean that it cannot be done!

It's even easy to complete the project, but it takes a long time.

"If you want to fundamentally solve the problem, you must let the old channel of the Yellow River go to the sea, so after this Northern Expedition, no matter what, you must lead the Yellow River out of the old channel to the sea, otherwise, you can't solve the problem of the Huai River!" Zhu Mingzhong's words were not loud, but he set off a wave in his ears, he had traveled to the north and naturally knew that hundreds of years after the Yellow River seized Huai, now the lives of the people in the middle and lower reaches of the Yellow River have undergone tremendous changes, the old road of the Yellow River has become a new living area, and there are a large number of people living there, and now the king wants to return to the old river again, which ...... This.

"King, this old river has been in disrepair for many years, if you take the liberty of moving the river north, I am afraid it will bring hidden dangers......"

"Hidden dangers?" With a slight raising of his eyebrows, Zhu Mingzhong said with a smile.

"What is the hidden danger, it is nothing more than to rebuild the embankment, this money, compared to the silver on both sides of the Huai River every year, is simply a drop in the bucket, not worth mentioning! Huang Qiang Huai weak is the Huai River out of the sea is not smooth fundamental problem, want to solve the problem, it is necessary to let the Yellow River north return to the old river, in this way, can also solve the problem of Haizhou Port siltation, once there is no Yellow River sediment as a supplement, these years the sediment accumulated on the north coast of the river will be eroded by the waves, less than a hundred years, the north coast of the river can return to normal...... "Of course, those eroded coastal sediment will sink into the sea, but under the action of the current, deposited in the south, the formation of the so-called in later generations

"Northern Jiangsu tidal flats" as well

After all, the sediment carried by the Yellow River now only makes the Fangong embankment a few miles away from the sea, far from being hundreds of miles away from the sea in later generations.

"As for the Huaihe ......" gazed at the land of Jiangbei, thinking of an article that he had read in another time and space.

"As long as the problem of the Yellow River is solved, the problem of the strength of the Yellow River and the weakness of the Yellow River no longer exists, and then all we need is to use the power of nature to restore the Huai River, and the siltation in the middle and lower reaches of the Huai River can be used

"Restraining water and attacking sand" and other methods to solve the problem......" Zhu Mingzhong mentioned

"Binding water and attacking sand" is a method of river control invented by Pan Jitao in the Ming Dynasty, according to later generations

"Pan Yinchuan uses the embankment to restrain the water, and the water brushes the sand, which is really the principle of nature, and it is not a delicate theory at the beginning, so those who talk about the river in the future must be regarded as Jinkeye." Perhaps this method was limited to historical conditions when controlling the Yellow River, and the measures taken by Pan Jitao could not fundamentally solve the problem of the Yellow River's harm at that time.

"The Panji River is confined to the lower reaches of the Yellow River below Henan, but the middle reaches of the sediment source are not treated. It is impossible to transport all the sediment into the sea by relying only on the measure of restraining the water and attacking the sediment, and a part of the sediment will inevitably accumulate in the downstream river. Therefore, after the river is controlled, the partial diversion of the breach still continues to occur, and the effect of accumulating and brushing yellow is not ideal. Because the problem of the Yellow River being strong and weak has not been fundamentally solved, but if we return the Yellow River to its original path, there will naturally be no more use of the problem of the Yellow River's weakness

Without the sediment of the Yellow River as a supplement, the sediment in the abandoned Yellow River waterway in the north of the Yangtze River will naturally be continuously carried away by the water of the Huai River, and over time, the Huai River's outlet channel can also return to normal, or basically return to normal. Of course, this is not Zhu Mingzhong put forward, in fact, as early as the late Qing Dynasty, the Republic of China and even New China, there are hydraulic scientists who put forward the problem of borrowing the Yellow River waterway to lead Huai out of the sea, but at that time, the problem of the high riverbed of the Yellow River restricted the realization of this idea, and now it is different, not after the experience of the Yellow River in the next 200 years, and the sediment brought by the Yellow River is the most after the 17th century - the Jiangbei coast is hundreds of kilometers deep into the sea after the 17th century, before that, the Jiangbei coast only stretched forward a few kilometers.

It is precisely because of the relatively small amount of sediment on the riverbed that Zhu Mingzhong believes that the use of the method of harnessing water and attacking sand can make the Huai River return to attack, at least there is this opportunity, of course, this process will take a long time, even hundreds of years, but if this problem can be solved, after a hundred years, the Jiangbei and even Henan will be restored to the land of fish and rice in the past, after all, the entire Huaihe River basin is not limited to Jiangbei, but also includes the southern part of Henan.

As for the so-called diversion of the Yellow River into the Yellow Sea, which can create new land in the Yellow Sea, those barren silted saline-alkali lands are not worth mentioning compared to the interests of the entire Huai River basin.

Rather than sacrificing the entire Huaihe River Basin and making it a harmful river, so that millions of people in the basin fall into a situation of continuous drought and flood in exchange for a little silted saline-alkali land, it is far better to use this energy and financial resources on the expansion of overseas territories and colonies, after all, the world in this era is simply a blank, waiting for the Ming fleet to fill it, waiting for the people of the Ming Dynasty to emigrate.

As for the problems of navigation and other problems that immigrants need to solve, they can always be solved, even if they cannot be solved for the time being, they can be solved by all means, and as for the domestic ...... Instead, you can recuperate and restore nature with the help of nature.

"The king is from a lofty position, and it is definitely not something that the ministers can comprehend!" Although as a soldier, Wang Anmin is not good at sycophancy, but it has long exceeded the scope of his understanding, and it is precisely because of this that he said this, and then Zhu Mingzhong realized that this was the admiral of the fleet beside him, not the army he joined the army.

So he said with a smile.

"In this way, this Haizhou port can also be saved, and even because of the effect of the current, this originally somewhat silted strait will become deeper, and then you need to worry about the fleet port being filled with sediment?" As far as the base camp of the navy is concerned, Qingdao is too north, Hainan is too south, Lushun is too small, and Dalian has no barrier, in contrast, there is no area more suitable than Haizhou to serve as a naval base camp, not only because of the area of Yuzhou Island and the area of the strait, but more importantly, its geographical location is located on the middle line of China's coastline, as long as the problem of sediment is solved, it is the best choice as a naval home port.

And it's not just a bay with a narrow mouth to the sea, it's a strait as a mooring ground, even if the enemy wants to implement blockade tactics, there is no way to close the strait that is several miles wide, but the water is not deep enough!

"King, if the water is too deep, it's not good......" Before he finished speaking, Zhu Mingzhong, who was still worried about the lack of water depth, smiled.

"The depth of the water has the advantage of the depth of the water, after all, in the future, the ship will always be bigger and bigger......" Maybe according to the current development trend, maybe in a hundred years, China will build ironclad ships, who knows?

Look at the oak saplings planted on the hills near the fortress, which the fleet worked out to solve the problem of timber for shipbuilding

"Afforestation" plan, 10 zhang on both sides of the official road in Jiangbei, as well as river embankments and barren mountains will be planted with oak trees, of course, in the future, North American red oak will be planted with better materials, and now only oak trees of the same family can be planted.

In the future, such a policy will be extended to the entire Ming Dynasty. Timber decides the fleet! The navy made a time-consuming choice to solve the timber needed for shipbuilding, but they did not know that perhaps in another hundred years, when these oak trees were made of wood, perhaps, the era of wooden sailing ships would be over.

Perhaps, by that time the world had already entered the era of ironclads, who knows? However, Zhu Mingzhong will certainly not object to the Navy's plan for cultivating forests, after all, in the future, it is not only the need for oak for shipbuilding, but also for other more extensive uses.

"Look at these ships......" pointed to the sailing ships in the strait, which were mobilized from all over the country for this expedition, and it can be said that almost all the ships in Jiangbei, including Taiwan, were gathered.

"In order to transport 50,000 troops to the Northern Expedition, we mobilized more than 300 ships, and if the ships were larger, maybe only a few dozen ships would have been needed to transport so many troops...... In the future, ships will get bigger and bigger! When talking about the Northern Expedition, Zhu Mingzhong's eyes stared at the dense white sails in the strait, the Northern Expedition, compared to Zheng Chenggong's Northern Expedition, perhaps, this is the real Huanglong......
