When are open-ended AquaDams used?

An open ended AquaDam can be used crossing a canal or stream when the banks of the canal or stream are in an elevated position. The stream bank is what keeps the water from running out the ends of the AquaDam. Open ended AquaDams go bank to bank.

AquaDams with one end open and the other end closed with attachment collar go from open end elevated upon the bank to the closed end, determining where the AquaDam will stop, such as half way across a river. Then a connection can be made. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
