S-1 Overview Bridge waterways commonly narrow or constrict natural channels, forcing water to flow through a contracted area, thereby increasing the magnitude of velocity and turbulent kinetic energy of flow passing through the waterway. If these increases cause erosion of the waterway boundaries, the contracted section may scour.

S-2 Revised Clear-Water and Live-Bed Contraction Scour Analysis researchers in this field. Specifically, the following factors associated with the objectives of this study were addressed: • Definition of contraction ratio • Summary of limitations/applicability of existing datasets and approaches • Multiple modeling techniques, such as physical modeling and computational fluid dynamics (CFD)

Summary S-3 The approach flow to a contracted channel is non-uniform and assumes the form of a gradually varied flow (backwater) profile.

S-4 Revised Clear-Water and Live-Bed Contraction Scour Analysis produces reasonable if slightly underpredicted estimates of equilibrium post-scour contraction scour flow depth. In addition, the reliability of the contraction scour prediction is significantly increased.
