Project Details

Project Description: 

The study extends the recently completed research on this subject. The completed study looked only at a tight range of soil properties and reviewers recommended to move forward with additional research to cover a larger range of cohesive soils. The results of this research will also benefit the new scour design concept based on 'Hydraulic Loading and Soil Resistance' to determine the critical soil resistance for cohesive soil layers.

Goals:

The primary objective of this study is to develop design tools for scour in cohesive soils that will be implemented in Hydraulic Engineering Circular No. 18, "Evaluating Scour at Bridges."

Deliverables

Deliverable Name: 
Design guidelines for scour in cohesive soils and to determine cohesive soil erosion resistance.
Deliverable Type: 
Research report or guidelines
Deliverable Description: 
The primary objective of this study is to develop design tools for scour in cohesive soils and cohesive soil erosion resistance that will be implemented in Hydraulic Engineering Circular No. 18, "Evaluating Scour at Bridges."
