In free-surface turbulent flows, large amount of air may be entrapped and advected in the
water current. The resulting air-water flows are frequently observed in natural water systems …

Computational fluid dynamics (CFD) is increasingly applied in the study of fishways.
Applications and methodologies, however, vary substantially among scientific studies and …

Connectivity is critical for stream fish persistence, and fish passage structures are a useful
conservation tool to reconnect fragmented systems. The design of fish passage structures is …

This paper presents the design and implementation of a sewer inspection robot that utilizes
the A-Star algorithm for pathfinding. The robot is intended to provide a more efficient solution …

Un déclin des populations de poissons a été observé ces dernières années, en partie dû à
la présence de barrières hydrauliques le long des voies migratoires-tels que des barrages …

A culvert is a covered channel designed to pass water through an embankment. The
adverse ecological impacts of road crossings on upstream fish passage has driven the …

This research aims to enhance our understanding of the behaviour of two Southern-
Hemisphere small-bodied species, Galaxias maculatus and Galaxias brevipinnis, during …

Culverts are covered channels designed to pass floodwaters beneath an embankment,
typically a roadway or railroad. Figures 1 to 3 present a few examples of box culvert …
