ABSTRACT
ABSTRACT Bridge scour is one of the main causes of bridge failures in the United States. Due to climate change and its associated extreme hydrological events, bridge scour becomes more severe and frequent. Therefore, hazard analysis for bridge scour evaluation must consider the detrimental effects of climate change. In this paper, a systematic approach is proposed to analyze the hazards causing bridge scour, in particular, flooding with extreme flow discharge. The future and/or ungauged discharge data are obtained by using hydrologic modeling at watershed level. The climate change impact is considered using projected climate data based on the global climate model and different climate change scenarios. The proposed approach is applied to the Charles River watershed, Massachusetts, New England, United States.
