Scour around bridge piers of overflow structures at I-35 Bridge on the Cimarron River (FHWA-OK-88-2) 2150
Abstract
The October 1986 flood of the Cimarron River resulted in severe scour around
piers of eight overflow structures of the 1-35 bridge. A major portion of the flood
passed through these structures resulting in a high velocity of flow. Furthermore, the
bridge is located on a meander, and that leads to a skewed, flow in the flood plain.
This fact caused additiona scour around the piers. The scour was measured using the
Electronic Distance Meter. After th?? flood receded, the maximum depth of scour
ranged from IO feet to 30 feet.
