Culvert Scour Assessment

The purpose of this study is to quantitatively analyze 1) the geomorphic and structure controls on channel-bed and footing scour at road-stream crossings, and 2) the effectiveness of aquatic organism passage at these crossings by comparing channel characteristics within the crossing structure to reference channel conditions not influenced by the structure

Decision Analysis Guide for Corrugated Metal Culvert Rehabilitation and Replacement using Trenchless Technology pdf
