Florida Rock-Clay Scour Procedure
The Florida Rock /Clay Scour Procedure is designed to account for the scour resistance of cemented strata, rock, and clay. The test methods establish the shear stress response of soils and the procedure integrates that response over the lifetime of expected flows at the bridge site. The procedure involves establishing the shear stress response of a site-specific sample using the RETA and SERF devices above, and then integrating that response over the flows expected in the life of the bridge to predict contraction or local scour at the bridge.
