  • Abstract:
    The design of culverts to accommodate aquatic organism passage (AOP) requires an understanding of organism habitat

    requirements, swimming ability and migration needs, as well as an understanding of how a culvert design will perform in a

    specific geomorphic context. This report documents existing reports on culvert design for AOP in Minnesota and nationally.

    The following review is designed to build upon the work of Hansen et al. 2009 and 2011 to: 1) summarize current aquatic

    organism passage practices, 2) summarize aquatic organism passage needs for Minnesota species, 3) discuss the importance

    of roughness or streambed sediment within a culvert in different systems (high, medium, or low slope) in single and multiple

    barrel systems, and 4) summarize physical experiments of sediment transport and geomorphic processes through culverts.
