Abstract

This research has three main objectives. First, select three bridge sites in South Dakota with long stream flow records (> 50 years) to compute the scour histories using the Scour Rate In COhesive Soils (SRICOS) method. The results will be analyzed to understand the relationship between time sequence of flows, rate of scour, and final scour depth to answer the fundamental question of how the characteristics of a hydrograph such as flood magnitude and duration, and the order of occurrence of floods would influence scour development in cohesive soils. Second, develop a decision tool to identify the types of field situations where the SRICOS method will be appropriate and beneficial. Third, provide guidelines for hydrologic analysis and hydrograph generation for using the SRICOS method based on the site conditions and project requirements.
