Adequate Selection of Design Flood Frequencies for the Evaluation of Scour and Scour Countermeasures of Critical Bridges, and their Impact on the Puerto Rico Highway and Transportation Authority’s Bridge Program
(Polytechnic University of Puerto Rico, 2023)
Federal regulations require all bridges, over waterways, to be designed for scour resistance and all existing bridges to be evaluated for scour vulnerability. Scour evaluations are typically based on the hydraulic design ...
1D and 2D Hydraulic Modeling to Estimate Bridge Scour: A Case Study
(Polytechnic University of Puerto Rico, 2021)
Scour is the effect of erosion of soil surrounding a bridge foundation due to fast-flowing water. This dynamic phenomenon can be categorized as the most common cause of bridge failures. Therefore, scour depth at piers and ...
