Computational Study of Fish Passage through Circular Culverts in Northeast Ohio

An investigation has been carried out in Northeast Ohio to determine the percentage of culverts that act as barriers for fish passage and to identify the design parameters that can be associated with passage success through stream simulation in two computer programs - FishXing and HEC-RAS. The results from HEC-RAS shows that, out of 40 culverts analyzed, 55% are partial barriers and 45% are complete barriers. A comparable analysis in FishXing analysis suggest that out of the 54 culverts analyzed, 11% are partial barriers and 89% are complete barriers. Student's t-tests (p ≤ 0.05) showed that the difference in the average perched height between partial barriers and complete barriers was significant for the output of both programs. Additional analysis was carried out in FishXing for greenside darter and largemouth bass by increasing diameter, decreasing length, decreasing slope, increasing Manning's roughness (n) of culvert material, and embedding the culverts with gravel substrate (n = 0.04) independently to examine the effect of those parameters on passage success. For greenside darter, embedding the culverts resulted in 36% of the culverts turning from complete barriers into partial barriers and had a greater impact on increasing passage success compared to varying other design parameters. Similar analysis for largemouth bass exhibited a less noticeable difference.
