Between Omaha and Des Moines, 7 miles South of I80 | Thanks for the reply. This stuff is kinda "your wheelhouse", I believe. Your comments, about using filter fabric, will be helpful, in 2 other culverts, where heavy rains, just move the 3" gravel on their outlets (they already have tapered end sections, at both ends, but I wished I had thought about that filter fabric, before I laid old concrete blocks and 3" gravel, at each outlet) That sounds like that would help, in our pasture area, too. Note: I've watched this videos, about culverts, twice, over the last couple years (kinda interesting for a farmer) https://www.youtube.com/watch?v=8vmTYmt0Y8Q&list=PL5_sm9g9d4T26H-wyM5Xa5GhDyTU2HcOw |
