Pier Scour Prediction in Cohesive Soils: Use of SRICOS-EFA Method in Illinois

The Scour Rate In Cohesive Soils-Erosion Function Apparatus (SRICOS-EFA) Methodology provides a potentially useful methodology for assessing scour in cohesive sediments. Most methods for predicting pier scour use erodability estimates from data collected with cohesionless soils. These estimates generally overestimate the scour of cohesive soils and needed depth and cost of piers. The SRICOS-EFA method holds promise in addressing the issue of scour in cohesive sediments, but field validation data are limited. The overall objective of this study is to test and potentially validate or improve the SRICOS-EFA method for estimating scour depth of cohesive soils in Illinois streams.
