Damaged Bridges over Watercourses and Stream Order Flood Analysis

摘要：

The paper describes how data about floods and bridges, which were damaged by the floods, were used for analysis. The paper is focusing on determination of watercourse segments with higher risk of exceeding hundred-year flow level. This is important because bridges are designed for n-year recurrence flood flow, generally for hundred-year flow. Two analyses were performed. Data were analyzed from hydrometric stations about n-year recurrence flood flows and extreme (real) flood flows. Watercourses were evaluated by Strahlers stream ordering method and confronted with bridges damaged by floods.
