Local scour around two pipelines in tandem in steady current
, 2014 In this study, local scour around two identical pipelines in a tandem arrangement are investigated numerically. Two-dimensional Reynolds-averaged Navier-Stokes (RANS) equations are solved for simulating the flow around the pipelines and the conservation ...

Multi-approach analysis of maximum riverbed scour depth above subway tunnel
Water Science and Engineering, 2010 When subway tunnels are routed underneath rivers, riverbed scour may expose the structure, with potentially severe consequences. Thus, it is important to identify the maximum scour depth to ensure that the designed buried depth is adequate.

Effects of pile caps on local scour at bridge piers [PDF]
, 2006 The most existing pier-scour equations mainly apply to uniformly shaped piers. However, pier footings may often project above the streambed because of scour. This may be caused by either long-term bed degradation or local scour.
