Open-bottom Culverts in Nebraska

The overarching goal of this research is to provide the Nebraska Department of Roads (NDOR) with a clear procedure for assessing the practicability of bottomless culverts installation at stream-crossing construction sites. Exact definitions of practicability will be established by the permitting agency, but the project will provide a frame work that can be used to assess practicability, depending on real-world site characteristics, some that are already known, some that will be identified as a result of literature review, and some that potentially will be identified as the research progresses beyond the literature review. Based on the above goal, the following objectives has been identified: (1) Literature that is relevant to bottomless culverts, including state-of-the-art examples, stream stability issues, biological issues, local erosion issues, local soil properties, and hydraulic issues will be reviewed. (2) Focusing on stream stability, criteria that impact the feasibility or practicability of bottomless culvert installation will be identified. (3) A reproducible methodology for evaluating and recording stream stability and other pertinent stream characteristics in order to assess bottomless culvert practicability at stream-crossing sites will be established. (4) In collaboration with NDOR personnel, potential design alternatives that can be tested further for effectiveness for Nebraska conditions will be identified. This work will provide a framework for identifying locations where bottomless culverts are and are not practical. It is very likely that bottomless culverts will be required in some locations in Nebraska. At the end of the project the research team expect that NDOR may want to evaluate new bottomless culvert design ideas and design modifications since existing bottomless culverts are generally found in locations where stream characteristics differ significantly from those found in Nebraska.
