the river is about 15m wide. Height of the rubber dam should be about 1.5 to 2m.
Hope you could help. :-)

Rubber dam, huh? I see all kinds of ideas coming off this site. Yours is really off-the-wall. Rubber is far more expensive than concrete, and surely less viable for such a project. You would be better off taking the same amount of rubber, build a huge rubber band and launch space vehicles to the moon. That is just as practical.
Keep thinking, dude, and something else will turn up. You're young. Something will hit...

Rubber is not strong enough by itself to withstand the stress caused by the upstream water pressure. Also it is not heavy enough to withstand lifting pressure from water that seeps underneath.
Rubber could be used as a membrane to seal off an earthen or rock dam to prevent excessive leakage. Plastics are also used, but either way it is a temporary measure as these materials disintegrate with time and solar exposure.

I don't have an answer to this question but wouldn't it be impractical to build a rubber dam? It wouldn't allow water to sift through to the other side. It could cause water levels to rise significantly on the other side. (I'm not very educated on this subject, sorry)
