ABSTRACT
A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the ten-ain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. Scom occurs due to the effect of erosive action of flowing water, removing and carrying away soil material from the bed and banks of streams and from around the piers and abutments of bridges. Bridges can be adversely affected by wind, water, loads on the bridge (traffic), etc. In this project, bridge scour of an existing bridge will be estimated using two (2) bridge scour estimation manuals; BD 97/12 (the Assessment of Scour and Other Hydraulic Actions at Highway Structures), and HEC 18 (Hydraulic Engineering Circular No. 18). After.vards, an in-situ measurement of the existing scour bridge will be taken to compare which of the bridge scour estimation manual best estimate bridge scour in Nigeria.
