A city called Vulcania that was able to pioneer the northern forest.
Going south from there, the river is flowing.
The castle north of the river is now almost an accommodation town for coming from the city of Fontana to Vulcania.
A river that leads to the moat of the castle, but then flows west.
Hot springs erupted at a point traveling west from the castle in the north of the river.
I'm pulling the hot spring from here directly through the cured brick tube to Linda Village, the neighbouring village.
It's just like a simple spring that doesn't even smell like sulfur when it comes to hot springs.
There is no such thing as crops being difficult to grow downstream of the river, so water downstream than a fountain pond could also be used as agricultural water.
Basically four villages in the western position from Vulcania are my territory.
Considerable yields are expected as those with the Barca surname actively improve the land within this territory.
Perhaps once or twice a year, to the extent that wheat is harvested, there will be no more water in the land.
Because it snows in the winter.
The problem is if [soil improvement] is repeated over and over again to produce vegetables with short growing periods.
Many farmers with the Barca surname do it because this way they can pick unprecedented quantities of food.
but in that case, brother hector is worried about what the moisture content of the land will be.
Let's keep it now so we can pull water from the river for that.
That's what happened, but I might not be able to deal with it right away when something happens when I make a tube that goes through the ground like a hot spring.
Very troublesome then.
Therefore, I want to be able to provide water in a stable manner even without me.
So let's use it as a dam so that we can supply water for the river.
Dig the ground in the middle of the river, keep it in a large pond, and if necessary open the plug connecting it to the waterway so that water is transported to the agricultural land.
I was going to make it that way as an image.
"I'm glad you followed me, Brother Ars. If it had been acted upon just by the thought of it, would it have been a flood?
"I'm sorry, Kyle. Though I wanted to build a dam, I almost worked without thinking about how to do it."
"All of a sudden I built a wall next to the river and it was a levee, I was surprised when I said something. Wait a minute. I'm going to calculate the amount of water and stuff properly, so I hope Brother Ars will change the terrain as Bogus and Gran say."
"Yes, I understand. Best wishes, Dr. Kyle."
If you go over the ground big enough to build a wall by the river, like a levee, it will be a pond that will store water, Lake Tortoise Dam.
That's what I thought.
but suddenly Kyle, who was rushing to come with me when he saw me start working, went into a stop.
That would be so.
If I made it that way, it would usually be nice, but if the amount of water increases due to heavy rain, etc., it would be a big deal.
Assuming there is more water beyond the dam's tolerance, and even if the embankment collapses, we don't know what kind of damage will happen to the surrounding area.
When I heard that, I stopped working right away, too.
I'll build a tower where Kyle tells me to, check the terrain with binoculars from the top of the tower, and interview old people in nearby villages and other people about what heavy rains have been in the past on the land around here.
Based on that information, Kyle and Grant created a blueprint.
Especially amazing is Kyle's magic.
The structure of the dam will be determined on the basis of the data, starting at high speeds with the amount of water, momentum, and expected changes in water level.
Until now, when building roads, etc., it is possible that a seriously calculated structure can be built in Barca, which was forced to build a straight road in the middle without surveying techniques.
"Kyle's magic is amazing. Really, a genius."
"I suppose so. Awkward people will want to try the same magic when they look at Lord Kyle."
"You really are. Yeah, because of that, and why don't we name the dam we make here so we can see how awesome Kyle is, like Kyle Dam or something?
"I hope so, Lord Ars. It's the biggest compliment to have a maker named after you. One day, the awkward will want to make something splendid and name it Gran."
"Haven't you since you named Gran on the hard tooth sword? Well, there's always a chance."
"Is it true, Lord Ars? I want you to promise me that if I have to make something, I will speak to the awkward."
"Okay, okay. Gran takes care of me. When the time comes, I'll ask Gran for it."
Speaking to Gran like that, it looks like all Kyle's calculations are done, too.
A blueprint for a solid dam will be completed so that there will probably be no flooding in the future.
Based on that, I proceeded with my work.
In the end, we were to try to stop the water flow along the river and save the water.
So instead of suddenly digging through the place, connect upstream and downstream of the planned dam construction site once with a newly dug surrogate waterway.
Make it look like a bypass, change the river flow, and in the meantime get your hands on a dam construction site.
The area beside the river is also reinforced by consolidating the ground so that the water is well stored and not shredded by the flow of water.
Then, while ensuring a constant or higher water level, a dam drainage path is provided so that the flow of water can be regulated so that it does not accumulate too much.
In addition, it is necessary to allow water to flow from the dam to the field to the waterway if necessary.
Honestly, I didn't fully understand what mechanism was affecting me.
but I will work silently as directed, believing that Kyle and Gran are "okay with this".
Basically, my magic is the main thing, but let me use people to make places that are fragile and so on so that I can repair anything other than me as long as I have a brick.
Thus, the Knights of Barca created a dam capable of securing only a steady supply of water to all villages and preventing flood damage.
