Geotechnical Limit to Scour at Spill-through Bridge Abutments: Laboratory Investigation (Mar 2015, MPC-15-280)
Scour of spill-through abutments occurs due to the combined influence of geotechnical and hydraulic processes. The present study is among the first to address the geotechnical process associated with the failure of the compacted earth, spill-through abutments, and the effects of the geotechnical strength...
Insights from Depth-Averaged Numerical Simulation of Flow at Bridge Abutments in Compound Channels (Jul 2011, MPC-11-237)
Two-dimensional, depth-averaged flow models are used to study the distribution of flow around spill-through abutments situated on floodplains in compound channels and rectangular channels (flow on very wide floodplains may be treated as rectangular channels). The study leads to useful insights regarding...
