Swale - Keypoint - Keyline - clarification

let's talk about swell a key point and key line which are three different cultures and there is confusion between the treatment of the trick onset are related to water and the way water flow he'll focus on so we just talked about swell what is the purpose of as well how to create a swell and what is the way to do that we see here in and well will be the tranche we do following the same attitude imagine we do now what we do with the again and we do that and we create the tranche the same altitude etc so what will happen in Aegina it's a heel you have dug the trench right up I'm very importantly at the same high head meaning that there is no declination and one the water is falling what I will I'm falling from the top what I will actually let into this one here if it's well done should not tell me okay so the slide the water accumulate here and over time will you try to solve and we dry the soil if there is not this well Matt you're under the water will flow on the bottom and usually with a strong wine will remove the top layer with all the fertility and then you will have a narrow deal and with little vegetation to the swine we sell to that with have in throwing the water catch capturing the water so that the water will remain here another time will we shrink right the sub sorry as well okay importantly it has to be at the same level or Alice's not so that the water does not flow in that direction or that direction as I'm talking we'll talk about the key point from reminders okay we really we have what what is here so convex shape meaning is like that okay the really from really shape concave is like this the transition between this convex shape curve and this concave one here in the middle and the transition point is the key point why the keypoint important it's in terms of touring water we see that now let's consider I have the money available or the resource available to do a done of this size aside 5 meters I 40 meters long I want to make a done to to capture the water the water rainwater which going from the top will go there and there will be a work done to keep this water yes is my key point is here and I put this dam at the key point okay here and if I put what else you can see that the quantity of water which is toward here which you see when it's quite low there's not a lot of water accumulating why because the angle between the dam and the hill is really sharp so this version which is here in addition now if I put underneath mine yeah consider what our which we go in it much much much bigger a lot of water okay I'm logical because with a low declination you can imagine that travel much larger volume of water meaning that one child adult is identified the point then you will put your done the bit below the key point and with the same effect not as a fault on a or resources to build is done you will have a much bigger larger putting of water and this water you can use them and we can put your house in Oregon turn and your garden here and uses water to boil for the house and for the garden if you put your out here you have no way to keep water to store a good quantity of water the same here so intellectually we the key point very important to identify where to put them we have to put the storage what was the range and therefore the house to take advantage of what else to write by gravity now let's talk about key lines key lines is not so much about throwing water it's more about the water dynamic when it's raining how what is the behavior although on the rain of the water which falling on the farm if you have a shape like this it's not exactly round and relax a bit oblong like that what will happen if we if when the rain is coming near it will choose the shorter way down meaning the water will not go that direction the water will most of the water we go that direction because it should not shop duration on the lose disruptive shuttle go we were there okay so I see that most of the water you can see their realtor we go on that direction and we see we go in or here so either this side or this side an interpretive water or the framework we the plan is that we need to do as well a lot of water we will have an effect so that the water will go over this word because it's full and we go there are not will not go there because it's too quick a little mix of the flow net water goes bad election so the idea of the keyline is not to make a swirl which is always not on some level but to give no like a kind of direction so it will go no down when it goes to that shot opt out of the hill so when the water goes down like this you know me clearly part of the water with water and part we go on that direction and we'll eat right this part of the other hill which otherwise would be keep keeping cry because water we go muskie in that direction usually key lines are not as big as well are more like small trench so that dynamically there is a distribution of water on the part of the hill which are usually avoided by the flow of water within direction look at it the water we go that direction and because the key line is going down like that get down some of the water will follow this direction following the flow down and we read that part of the hill okay which is running naturally is not directed lets me know the difference in July 9 and 12 in this example we we are even know picking example of how the flow of water is going to when rain will will fall here when we go not go down on the branch of the hills like this what what I will do what are we directly go down and the shorter the shortest way to down ok and we need through the region there so the question is second part if you are in a country with very little rainfall for control for 1 month to month Danya and you want to refer s I'm not sure that key line this idea of wage writing that there is the best solution because if you have only 2 years to 2 months of rain what you want to do you want to focus where the humidity stand meaning you want focus here as you know that here you will have the most humidity because all what over there and maybe start to visualize that areas yes and start to stratification starting from that area because you are you are no insurance that refreshes with rotation will we take place and then you can stretch another time of course you can you can help the situation with where to to keep the water here more and to stop the water so it doesn't go down say well there so to help this vegetation here and then after you can start to ponder on the branches of the hill here and here
