Issues with Streambed Simulations using Countersunk Culverts
Hard to explain what sinking a culvert into streambed should look like. Often this important point is lost between designer and installer.
Design is often forced into bedrock areas where sinking cannot occur. Because bedrock not detected during inspection.
Filling in takes longer than expected, need to “embed” from the beginning not just “seed”
Are culverts wide enough using the 50 year design criteria in the guidance to promote or retain filling inside the culvert?
