Still don't understand
I still don't understand how these dams work. Is it walls on the side of river that only let a certain amount out? Seems like that would just make it flow faster? Is it a dam? But if it has no gates how would it be able to hold back more water during flooding? I just aint getting it. is it just a short levy on one side? —The preceding unsigned comment was added by 22.214.171.124 (talk • contribs) February 8, 2007.
- I added an external link which should help. The pictures in the gallery above don't appear to be dry dams. Malepheasant 22:25, 1 June 2007 (UTC)
Thank you, excellent link, pictures above should be deleted.
- Not sure I understand myself, but if there is a permenantly open hole at the base that the water normally flows through , and if you get a huge amount of rain then water slowly builds up behind the dam, and keeps pouring out of the hole at the base at a controlled rate, that would seem to make sense.
