A: Yes, and especially in the North American West, but most have failed, been hidden under earth embankments, or been replaced with entirely new structures.

Q: Are dams useful to anticipate any problems and permit remedial action to be taken before structural failure occurs?

A: Yes.

Q: Is dam dependent on the strength of the side wall abutments?
