Evaluation of SRICOS method on cohesive soils in South Dakota

"The SRICOS (Scour Rates In COhesive Soils) method had been proposed as an alternative design methodology for predicting scour at bridges founded in cohesive soils. As the new method can produce substantial savings in bridge construction costs at cohesive soil sites, it is important that South Dakota Department of Transportation (SDDOT) evaluates the method carefully for use in bridge design. This research project compared the predictions of the SRICOS method for pier scour with measured scour at three bridge sites in South Dakota and examined the technical issues involved in using the method."--Abstract.
