Culverts are critical structures that are designed to transport water from one side of a roadway to another while also bearing the load of traffic. Culverts are often grouped with bridges in the U.S. and thus hold a score of “C” according to the American Society of Civil Engineers (ASCE) infrastructure report card (Bridges, 2021). Culverts typically have a design life of 50 years, after which the culvert needs to be repaired or replaced. Typically, repair is favored over full replacement due to cost, potential disruption, and associated time delays.

The Manning equation is normally used for open channels, but it can also be used in pipe flow. It is common to use the Manning equation for flow through culverts or drains. Culverts are pipes connecting sections of open channel together. This will be discussed further in Chapter 5.

Culverts are long structures with a circular or square cross-section connecting flows at both sides of a road or dike (see Figure 5.9). They can also be applied if a canal crosses a small stream or ditch. In principle, the bed of the stream does not continue unlike the bed at a bridge or an aqueduct. Culverts are made of concrete or steel, generally. In the past, culverts were made of bricks, but wood was also used.

A culvert is a structure that moves water around an obstacle or through an underground canal. Culverts are often used as cross-drains to help ditches drain along the side of the road. They are also used to let water pass under the road where ditches and streams meet. A culvert is a structure that looks like a bridge that lets cars or people walk across a canal while it also lets enough water pass through. Widespread attention has been given to local scour, which is defined as the local movement of sediment around hydraulic structures. Therefore, numerous studies have been carried out regarding many hydraulic structures in a variety of settings, including spur dikes, gates, bridge abutments, and bridge piers. (Day et al. 2001; Kuhnle et al. 2002; Barbhuiya and Dey 2004; Dey and Barbhuiya 2005; Zhang et al. 2009; Sheppard et al. 2013; Wu et al. 2015; Ibrahim et al. 2018; Basiouny et al. 2018)

While the structural design of the culvert is simple, evaluating its hydraulic performance is still a challenging task due to the blockage problem with the presence of various types of floating debris (Ahmed et al., 2021; Iqbal et al., 2021b; Osman & Taha, 2022). A culvert is a short-length underground drainage structure to convey flood flows from one side of infrastructures such as embankments, levees, roadways, and railroads in urban areas or in the countryside to the other side. Culverts are also designed in different shapes and for a particular purpose for example to allow the passage of fish or animals besides their main purpose as a drainage structure(Chanson et al., 2021; Li et al., 2022). While the structural design of the culvert is simple, evaluating its hydraulic performance is still a challenging task due to the blockage problem with the presence of various types of floating debris (Balkham et al., 2011; Blanc et al., 2014; Iqbal et al., 2021a; Paik & Park, 2011; Zhong et al., 2021). Three different types of debris may be considered in hydraulic engineering including floating debris (generally different types of vegetation), non-floating debris (e.g. sediments), and urban debris such as structural materials and all types of fly-tipping (Balkham et al., 2011; Weeks et al., 2009). Some studies show that there is a range of locations and conditions where the blockage may be a concern in hydraulic designs (Diehl, 1997; Friedrich et al., 2022; Furlan et al., 2018; Spreitzer et al., 2021; Streftaris et al., 2013).

Anthropogenic, in-stream structures such as dams, weirs, and road-crossing culverts are widespread barriers that can cause significant fragmentation of aquatic ecosystems (Trombulak and Frissell 2000; Anderson et al. 2012). Effects of fragmentation are an important issue for managers and planners because in-stream barriers can impact ecosystem structure and function, i.e. the stream ecosystem’s goods and services (e.g. Mahlum et al. 2014; Torterotot et al. 2014; Erkinaro et al. 2017). The most common anthropogenic barrier causing fragmentation of river networks in forested landscapes are road crossings (Khan and Colbo 2008; Park et al. 2008). Many road crossings use culverts to facilitate the passage of water through road embankments (Clay 1995; Erkinaro et al. 2017). Culverts are hydraulic structures that carry water under roadways or other embankments (Doehring et al. 2011; Hall et al. 2011). Pipe-culverts are the most common in-stream structure used at stream crossings due to their low costs (Khan and Colbo 2008; Park et al. 2008). They can be variable in size, e.g. as small as 0.3m in diameter, and are typically installed for the singular purpose of transporting water through stream crossings by roads and thus rarely consider fish passage (Blakely et al. 2006; Makrakis et al. 2012). While there are guidelines intended to reduce environmental impacts on fish (e.g. Chilibeck 1992; New Brunswick Department of Environment (NBDE)) 2012), culverts alter stream morphology at the installation location and often increasingly so as a function of time, thus affect fish passability (Poplar-Jeffers et al. 2009; Price et al. 2010).
