Fdot scour manual

Pier scour: use either the equations in HEC, Froelich’s Equation, or Sheppard’s Equations. Limit d 50 to mm ( x 10 -4 ft or x 10 -3 in). For contraction scour, use the equations in HEC For pier scour, use the equations in HEC with a reduction factor of for soils with 11% or more clay.  · Florida Bridge Scour Manual.

In the mids, the Florida DOT began an intensive research effort to develop equations for estimating pier scour. Our efforts were not Florida-specific or initially focused on the tidal environment, but rather targeting the fundamental mechanisms of pier scour.

Sheppard's Pier Scour Equations. Dr. Sheppard’s equations targets three dimensionless hydraulic and sediment transport parameter groups to predict scour at simple piers. The equation is applicable to both riverine and tidal flows, applies to sediment sizes typical within the continental US, and gives good results for both narrow and wide piers. For scour critical bridges, a brid scour ge plan of action is also required, and must also be signed and sealed by a professional engineer. Item will not be coded “8” for any structure lacking documentation of a scour evaluation. Drainage Manual Posted: Octo FDOT Drainage Design Manual.
