Evaluating Shallow-Flow Rock Structures as Scour Countermeasures at Bridges

<p>The Utah Department of Transportation commissioned a study to determine whether or not shallow-flow rock structures could reliably be used at bridge abutments in place of riprap. Research was conducted in a two-phase effort beginning with numerical modeling and ending with field verification of model findings. As part of phase one, two finite element meshes were created in Surface-water Modeling Software (SMS) and analyzed with FESWMS-2DH. Second, field studies were conducted and a preliminary database was developed to track field studies conducted on 98 shallow-flow rock structures in Utah. Data organization in ArcGIS® and Microsoft Access® is presented followed by instructions on how to use the database. Both numerical model and field research results indicate that shallow-flow rock structures are not viable scour countermeasures at bridges.</p>
