Abstract

In current practice, inlet loss coefficients for buried-invert culverts are either ignored or approximated using traditional culvert design data due to a lack of data specific to fish passage culvert geometries. This study included the experimental determination of inlet loss coefficients for a circular culvert with an invert burial depth of 50%. Culvert inverts are buried when a simulated streambed is desired in the culvert for fish passage applications. This paper outlines the experimental methods used to determine inlet loss coefficients relative to fish passage culvert geometries and presents the data relevant to the hydraulic design and evaluation of these culverts.
