• 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.
