OK I can't remember for the life of me what kind of irrigation system/dam this is called. So I will try my best to discribe it. I thought I had it in my 18C MOS Book but didn't.
You use them mainly on ditches or run out streams, dry river/creek beds that fill with water when it rains in high Elevations. YOu can use them on Small Streams and Rivers too.
I'm basically looking for one in a dry creek bed that gets water, not really flash floods. But fills when it rain or rain comes down a hill/mountain side. Like you live down in a valley and you can see it rain up in the mounatins. You know by morning or with XX set of hours you will have rain coming down your creek/stream.
How the Dam or irrigation system works is you build three "walls" in a semi-circle. Each wall is seperated by a set distance due to the amount of water typically running down/along the creek/stream. The height of each wall is different based on the same factors. The first wall starts to slow the water down, second wall slows the water down to a stop spilling over into the third walled area. The third walled area spills back into the stream/creek to flow down stream. If there isn't that much water it still "catches" water to be used in the area.
There is a name for this kind of irrigation system or Dam system. That's what I'm looking for so I can google it. The measuremeants are base off river/creek size or amount of water flowing. Maybe stream velocity, etc. I know this is some Redneck Engineering, but it has a real name.
Looking for some help. Thanks
