colverts or whistle you know what mean

Be sure to create a catch basin on each end so that sediment settles out before entering the culvert. The more you can pool water and the less you let it run, the more infiltration you get and that will greatly reduce erosion.

overszd is right, dual wall culverts with smooth bore are the way to go. A smooth bore plastic will flow approximately 1/4-1/3 more water than a similar ribbed galvanized culvert.

Here's one I did but we couldn't get depth for a catch basin. Due to high flows, we rip-rapped heavily.

when you say creek, how big of a creek? does it flow all year or just in the wet seasons? How far is it from bank to bank? In my experience colverts are nothing but trouble especially when a creek is involved. Rip raf is good concrete is better for a head wall but even so it will haft to be rebuilt every so often.

The problem most people have with culverts is undersizing them. They get to the pipe store and decide to save a few bucks and go one size down from where they should, that and failing to keep the catchbasins clean of brush, leaves and sand.

One trick you could do is use two culverts, one slightly higher than the other. The lower one will plug with the debris and the upper tends to take the overflow, that said, nothing beats an oversize culvert to allow debris to flow through.

Just soil is normal around here and we get awesome flooding but the type of soil is important you don't want light soil or sand , Some heavy clay and pound it down in layers with the excavator bucket and get a fast growing grass or some cover on the surface .
