Evaluating Nonlinear Methods to Generate Flood Hydrographs for Bridge Scour Applications (Dec 2022, MPC-22-491)
Bridge scour evaluations are often performed using streamflow estimates from regional regression relationships. This approach relies on the accuracy of the relationships and does not consider the effects of flow variations. Alternatively, a complete hydrograph can be obtained from a watershed model and...
Flood Hydrograph Generation for Predicting Bridge Scour in Cohesive Soils (May 2022, MPC-22-459)
Three bridge sites in South Dakota with streamflow records ranging from 50 to 67 years were selected to compute the histories of pier or contraction scour using the Scour Rates In COhesive Soils (SRICOS) method. Scour depths were computed using a range of soil erosion functions representative of cohesive...
