Abstract

Abstract: Floods affect the road route where the Alandeğirmeni bridge is located, causing traffic stoppage, traffic accidents, loss of life and property. Using hydraulic software related to flooding, we investigate this issue and show how to reduce the recurrence of floods. Using 100 and 500 year annual recurrent flood data, the existing bridge was analyzed and found to be inadequate. With the new modeling to be revised, flood risk is prevented. According to the findings of our study, the bridge was sized in such a way that approximately 1.5 meters of headroom is left when the 100-year flow passes and at least 1 meter of headroom is left when the 500-year flow passes. As a result of the analyzes and corrections, the safety of the bridges is ensured and hydraulic problems such as heave etc. that may arise from the bridges are prevented.
