Utility horizontal penetration effect on small dam
Utility horizontal penetration effect on small dam
(OP)
I have a small diameter utility pipeline crossing a small dyke/dam (around 2.5 m height). Dam authority is concerned about erosion potential of the dam body due to this horizontal penetration. Do you recommend anything for mitigation/prevention (of any detremintal effect on the dam due to this crossing) other than selected backfill and embedded materials as well as proper compaction. Any guidelines will be greatly appreciated. Thank you.

2. Graded sand filter as cvg suggests.

I take that back. The best thing is to do all of the above AND arrange it so the penetration is above the normal water surface.
A very large fraction of all dam failures by piping begin at a conduit through the embankment.
Now, backing up a little, is the pipe being laid along the dam lengthwise, or does it go through the dam the short way?
