Research method on scour at bridge piers

Numerous conventional methods, such as Laursen, Neil, Jain ve Fischer Gunyakti, Johnson, Melville, Richardson and Davis, Yanmaz methods, have been developed for the analysis of scour at bridge piers. In current work, the scour at the pier of the Ceyhan Bridge which was built in 1989 in the Motorway Network was calculated with the help of those methods widely used in literature considering the basin characteristics. The results of these conventional methods applied herein were also compared with the actual field measurements. In addition, HEC-RAS software was also used in determining the scour at the pier of the Ceyhan Bridge. Via the program, the amount of water debris on the pier and the amount of the scour around pier were calculated. According to the obtained results, the reliability against bridge scour problem was evaluated. The results showed that Yanmaz, Gunyakti and Laursen methods gave best results in comparison with the others.
