Enhanced Abutment Scour Studies for Compound Channels
PUBLICATION NO: FHWA-RD-99-156
This report describes a laboratory study of abutment scour for compound channels where the experiments simulated floodplains with defined channel and overbank flow areas at different elevations. A new abutment scour prediction equation was derived as part of this study and is presented in an appendix of the fourth edition of the Federal Highway Administration Hydraulic Engineering Circular No. 18 (HEC-18). This report will be of interest to bridge engineers and hydraulic engineers involved in bridge scour evaluations and to researchers involved in developing improved bridge scour evaluation procedures. It is being published as a Web document only.
