Book excerpt: The success of fish migration through culverts is dependent on the swimming ability of the fish and the hydraulic conditions of the culvert. Properly designed and constructed culverts can minimize the impact on fish passage. Because culverts are typically more economical than bridges, it is appropriate to evaluate when to use culverts and to predict the effects of such culvert installations. During the consideration of alternatives for structures for fish passage, culverts should not be automatically eliminated. This publication has tried to examine the aspects of culvert design and operation relative to the existing information that has been published in previous studies. Ideally, a culvert installation should not change the conditions that existed prior to that installation. This means that the cross-sectional area should not be restricted by the culvert, the slope should not change, and the roughness coefficients should remain the same. Any change in these conditions will result in a velocity change which could alter the sediment transportation capacity of the stream. A truly successful culvert design would include matching the velocities of the fish's swimming zone in the culvert to the swimming capacity of the design fish. Unfortunately, not enough research has been completed to make this an acceptable criterion of culvert design. This approach is preferred because it is easier to reduce the velocities in the swimming zone by increasing the boundary roughness than it is to reduce the mean velocity of the entire culvert. This publication contains some relatively simple guidelines which can reduce the installation problems of culverts in streams containing migrating fish when combined with the expertise of an experience fish biologist, engineer, and hydrologist.

Available in PDF, EPUB and Kindle. Book excerpt: The Bureau of Land Management and the Forest Service manage more than 41 million acres of federal lands in Oregon and Washington, including 122,000 miles of roads that use culverts--pipes or arches that allow water to flow from one side of the road to the other. Many of the streams that pass through these culverts are essential habitat for fish and other aquatic species. More than 10,000 culverts exist on fish-bearing streams in Oregon and Washington, but the number that impede fish passage is unknown. Ongoing agency inventory and assessment efforts have identified nearly 2,600 barrier culverts, but agency officials estimate that more than twice that number may exist. Although the agencies recognize the importance of restoring fish passage, several factors inhibit their efforts. Most significantly, the agencies have not made enough money available to do all the necessary culvert work. In addition, the often lengthy process of obtaining federal and state environmental clearances and permits, as well as the short seasonal "window of opportunity" to do the work, affects the agencies' ability to restore fish passages quickly. Furthermore, the shortage of experienced engineering staff limits the number of projects that can be designed and completed. BLM and the Forest Service have completed 141 culvert projects to remove barriers and to open an estimated 171 miles of fish habitat from fiscal year 1998 through 2000. Neither agency, however, knows the extent to which culvert projects ultimately improve fish passage because they don't require systematic post-project monitoring to measure the outcomes of their efforts

Available in PDF, EPUB and Kindle. Book excerpt: Low-level river crossings, including culverts, are important for delivering a range of valuable socioeconomic services, including transportation and hydrological control. These structures are also known to have negative impacts on freshwater river system morphology and ecology, including the blockage of upstream fish passage, particularly small-body-mass fish species. Given the enormous environmental problems created by road crossings, new hydraulic engineering guidelines are proposed for fish-friendly multi-cell box culvert designs. The focus of these guidelines is on smooth box culverts without appurtenance, with a novel approach based upon three basic concepts: (I) the culvert design is optimized for fish passage for small to medium water discharges, and for flood capacity for larger discharges, (II) low-velocity zones are provided along the wetted perimeter in the culvert barrel, and quantified in terms of a fraction of the wetted flow area where the local longitudinal velocity is less than a characteristic fish speed linked to swimming performances of targeted fish species, and (III) the culvert barrel is smooth, without any other form of boundary treatment and appurtenance. The present monograph develops a number of practical considerations, in particular relevant to box culvert operations for less-than-design discharges. It is argued that upstream fish passage capabilities would imply a revised approach to maintenance, in part linked to the targeted fish species. This reference work is authored for civil and environmental engineers, as well as biology and ecology scientists interested in culvert design. While the book is aimed to professionals, the material is also lectured in postgraduate courses and in professional short courses.

Available in PDF, EPUB and Kindle. Book excerpt: This new edition of the best-selling book describes the main types of fishways and fish facilities used around the world to assist the passage of fish over dams and other obstructions to their migration. It also focuses on the protection of fish (mainly young fish) from the hazards encountered in their downstream migrations. The book brings together the type of knowledge and research needed to decide on the facility used as well as its design and operation. It emphasizes the need for both biologists and engineers to collaborate in the design and indicates in what fields such collaboration would benefit fisheries conservation in the future. This is the Second Edition of the only book to bring together all of these topics worldwide under one cover.

This book was released on 2015-03-10 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, culverts have been designed for hydraulic efficiency without consideration of fish passage or, more generally, aquatic organism passage. Over time, it has become apparent that culverts frequently become impediments to healthy aquatic ecosystems because they can prevent the movement of fish and other aquatic organisms upstream and downstream through the culvert. Therefore, aquatic organism passage through culverts has become an important design element component for road/stream crossings. Common physical characteristics that may create barriers include high water velocity, shallow water depth, large outlet drop heights, turbulence within the culvert, and accumulation of debris. Sediment deposition and erosion at the culvert may also create a barrier to passage. Culvert length, slope, and roughness may create conditions that impede passage as well. Further complicating design is that passage needs differ by species, life stage, and season. To address this complex task, the Federal Highway Administration (FHWA) developed a stream simulation approach for designing culverts. Stream simulation is based on the concept that if conditions inside a culvert are similar to those conditions in the stream upstream and downstream of the culvert, then aquatic organism passage will be provided without consideration of the specific physical requirements of one or more species. However, stream simulation is not appropriate for all situations. For example, an existing culvert that is blocking passage may not be a good candidate for replacement using stream simulation because of the size of the embankment or insufficient budget for a replacement. Applications of stream simulation may also be limited for new culvert installations. Site constraints or budget limits could dictate a smaller culvert installation than would be recommended by stream simulation. In these cases, it may be desirable to design a culvert crossing considering the specific passage needs of a specific species of fish. Doing so requires an understanding of the migration seasonality, life stage swimming capabilities, and stream flow rates expected during passage. Ideally, this information is developed by a multidisciplinary team of aquatic biologists, hydrologists, and engineers. From this information, the maximum velocity and minimum depth requirements for the target fish are derived. Considering only average velocity in a culvert masks that there are zones within the flow field where velocities both higher and lower than the average exist. The objective of this research is to assist in the design of culverts for fish passage by 1) identifying zones of lower velocity that are conducive to fish passage and 2) developing practical design methods quantifying these lower velocity zones.
