I have read a specific term to describe the process when water pools behind a restriction such as a bridge during a flood. I cannot for the life of me remember what the word was.
The term specifically refers to the process of the ponding of water upstream of a restriction during a flood creating an area where the water pools higher and velocity is slower. Essentially the flood version of localised water detention due to a outlet restriction.
If anyone could help me out with the exact terminology that would be great. Have been searching all over to no avail.
