This study is a broad and critical review of the transdisciplinary literature on the construction
of culverts and their impacts on stream hydrology and geomorphology as well as on stream …

Fish speed and stamina, locomotion and the mechanics of fish swimming, are important to
the development and design of passage, exclusion, and guidance systems for fish. Such …

Culverts are a major cause of habitat fragmentation in freshwater ecosystems, are a barrier
to fish movement, and can be regarded as a significant contributor in the decline of …

Worldwide declines in riverine fish abundance and diversity have been linked to the
fragmentation of aquatic habitats through the installation of instream structures (eg culverts …

Fish and aquatic organism passage through culverts is an important component of road and
stream crossing design. Culverts represent an economical means of conveying water …

Installation of baffles intended to improve fish passage through culverts can reduce
discharge capacity and trap debris, increasing flood risk. A sloping upstream face may …

For some applications, fish passage through culverts may be enhanced by adding weir
baffles along the culvert invert. In an effort to evaluate the effectiveness of computation …

Laboratory tests were conducted with brown trout to evaluate their ability to pass through a
small, baffled prototype-scale culvert under a variety of culvert slopes and discharge …

To facilitate the upstream passage of small fish, corrugated culverts are often preferred over
smooth pipes, due to the lower edge and mean cross sectional water velocities created. This …

Culverts are rehabilitated using a variety of techniques; the approach studied in this report
focuses on the use of slip liners. Slip lining refers to installing a liner pipe inside a host pipe …
