The pier scour process is normally intensified in the presence of an ice cover, which poses risks to longevity and safety bridges. In present study, impact densimetric Froude number, locations, spacing side-by-side piers on local depth under ice-covered flow conditions were investigated based clear water experiments S-shaped laboratory flume. results demonstrated that at along convex bank was m...

We present an experiment designed to study magnetohydrodynamic effects in free surface channel flow. The wide aspect ratio channel (the width to height ratio is about 15) is completely enclosed in an inert atmosphere to prevent oxidization of the liquid metal. A custom-designed pump reduces entrainment of oxygen, which was found to be a problem with standard centrifugal and gear pumps. Laser Do...

It has been proposed that barnacle cyprids can maintain position in shorewardpropagating fronts by swimming upward against a downwelling flow, potentially mediating onshore transport of larvae toward intertidal habitat. This study developed a novel flume to characterize swimming behavior of barnacle cyprids in a laboratory downwelling flow. Seawater was pumped through a cylindrical observation ...

Gravel bed channels have a much greater capacity than sand bed channels to regulate the mobility of the bed surface through the formation of a surface layer of bed particles that is coarser than the particles supplied as load. The coarse surface layer affects bed mobility in two important ways. First, it reduces differences in mobility between coarser and finer particles on the bed surface by m...
