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 …

Standard box-culvert designs are similar to ancient designs. The acknowledgment of the
ecological impact of culverts and road crossings on rivers has led to changes in culvert …

A culvert is a covered road structure constructed to pass flood and drainage. The
engineering design principle of culverts focuses on optimising flood capacity at the lowest …

There are tens of thousands of dams and millions of road‐stream crossings in the eastern
United States (US) which can prevent fish and other aquatic organisms from accessing key …

Fragmentation of aquatic habitats is a global conservation concern. Losses of both
biodiversity and genetic diversity have been attributed to this phenomenon as dispersal …

The challenge to understanding the fluid mechanics of fish swimming is knowing exactly
what the water is doing where the fish swims. Recent field and laboratory observations in …

Many aquatic networks are fragmented by road crossing structures; remediating these
barriers to allow fish passage is critical to restoring connectivity. Maximizing connectivity …

Culverts installed at road–stream intersections are pervasive in many watersheds and can
function as dispersal barriers for aquatic organisms, thereby fragmenting watersheds. We …

Low-level river crossings, including culverts, are important for delivering a range of valuable
socioeconomic services, including transportation and hydrological control. These structures …

Fish movement in freshwater streams is often tied to patterns of flow, especially when the
stream is intermittent, flashy, or some combination thereof. Relationships between flow and …
