Determining the Percentage of Culverts That Act As Barriers to Fish Passage in NE Ohio https://trid.trb.org/View/2280276 24 inches), a discernible channel geometry, and circular shape (simplified analysis for this first assessment) to predict fish passage success rates. At present results of 55 culverts have been analyzed using FishXing and one culvert using an add-on HEC-RAS code that predicts fish passage. Results from the analysis using FishXing indicate that none of the selected fish species was able to pass upstream through any of the culverts during the 2 year flood, two of the fish (Greenside darter and Golden shiner) were able to pass on average 3% of the culverts during highest average monthly flow, two of fish species (Greenside darter and Blacknose dace) were able to pass on average 25% of the culverts during the minimum average monthly flow, and on average 13% of the culverts during the typical low flow day (25% low flow). Results obtained with the HEC-RAS tool showed only moderately better passage conditions, with the main cause for the barrier being excessive velocity, in spite of the streams' moderate hydraulic gradients. While additional analysis of the remaining culverts is necessary, both the method outlined and the results are expected to be useful in aiding fish passage analysis and design.]]> Wed, 27 Dec 2023 15:03:25 GMT https://trid.trb.org/View/2280276 Canada geese flight patterns in the vicinity of an aerodrome: Insights and management implications https://trid.trb.org/View/2140121 Fri, 24 Mar 2023 09:13:21 GMT https://trid.trb.org/View/2140121 Monarch Conservation Strategies for Texas Roadways https://trid.trb.org/View/2135533 Thu, 09 Mar 2023 17:08:38 GMT https://trid.trb.org/View/2135533 Distribution, Roosting and Foraging Ecology, and Migration Pathways for Gray Bats in Western North Carolina https://trid.trb.org/View/1894356 Mon, 13 Dec 2021 10:37:01 GMT https://trid.trb.org/View/1894356 Daily and Seasonal Movement of Brown Pelicans in the Bahía Grande Wetland Complex —Supplementary Material to R1 https://trid.trb.org/View/1889501 Mon, 22 Nov 2021 11:31:52 GMT https://trid.trb.org/View/1889501 Daily and Seasonal Movements of Brown Pelicans in the Bahía Grande Wetland Complex: Technical Report https://trid.trb.org/View/1889500 Mon, 22 Nov 2021 11:31:51 GMT https://trid.trb.org/View/1889500 Open-bottom Culverts in Nebraska: A Literature Review https://trid.trb.org/View/1852449 Mon, 04 Oct 2021 17:19:22 GMT https://trid.trb.org/View/1852449 Highway Hydraulic Engineering State of Practice https://trid.trb.org/View/1717027 Tue, 30 Jun 2020 10:37:05 GMT https://trid.trb.org/View/1717027 Do railway lines affect the distribution of woodland birds during autumn? https://trid.trb.org/View/1700415 Mon, 08 Jun 2020 14:16:38 GMT https://trid.trb.org/View/1700415
