Abstract

In this paper, the effects of different widths and lengths of collar around bridge abutment on local scour depth are studied numerically and experimentally. Numerical simulation of scour hole evolution at bridge abutment is more convenient than the experimental modeling, because the [...]

Abstract

The road infrastructure around the world is impaired by natural hazards, in particular with extreme flooding, which sever the road links and lead to serious socio-economic consequences. The bridges, which are the most critical parts of road links, are threatened even by less extreme [...]
