- Abstract
In recent years, extreme flow events in rivers have become more frequent and caused numerous bridge failures worldwide. Such events increase headwater levels in the rivers that may cause water to flow over the bridge deck, referred to as bridge overtopping. This is one of the primary factors affecting bridge functionality, possibly leading to failure. In general, bridges are designed and constructed to withstand certain extreme hydraulic events without interrupting the serviceability during the design life. However, changes in the catch ment physical characteristics as well as in the climate patterns have increased the likelihood of extreme flow events occurring, which can ultimately create conditions for bridge overtopping not...

In recent years, extreme flow events in rivers have become more frequent and caused numerous bridge failures worldwide. Such events increase headwater levels in the rivers that may cause water to flow over the bridge deck, referred to as bridge overtopping. This is one of the primary factors affecting bridge functionality, possibly leading to failure. In general, bridges are designed and constructed to withstand certain extreme hydraulic events without interrupting the serviceability during the design life. However, changes in the catch ment physical characteristics as well as in the climate patterns have increased the likelihood of extreme flow events occurring, which can ultimately create conditions for bridge overtopping not anticipated in the planning and management of bridges. Hence, there is an urgent need to reassess bridge structures for potential overtopping under current and future flow conditions. This study presents a method to assess the likelihood of overtopping of bridges in connection with extreme flows applied to several rivers in South Sweden, including Viskan, Rönne, and Lagan Rivers. The method adopted simplified hydraulic equations in combination with LiDAR data (for geometrical and topographic properties of river sections and bridges) and flow data for the bridge overtopping assessment.
