Intended Audience

This course is intended for Transportation engineers, roadway designers, contractors, municipal engineers, project managers, Hydrologist, and any persons working in the civil engineering field or anyone with an interest in highways in the river environment.

Benefit to Attendees

This course will cover design of highways in the river environment.

Course Introduction

In order to provide the most efficient roadway alignment for vehicle volumes, roadway alignments often encroach upon rivers. When this occurs the hydraulics and characteristics of the river have to be analyzed in order to protect properties upstream and downstream of the encroachment. Erosion & sedimentation, flooding and river morphology should be considered when highways encroach upon rivers. Several measures will be introduced in this course to mitigate problems encountered for highway in the river environment.

Course Content

This course River Engineering for Highway Encroachments - Part Two, will cover scour at bridges, data needs, and design considerations for highway encroachments.

Note: The student should study Section 7 through Section 9 of the following FHWA document in order to prepare for the quiz. The remaining text of the document is covered in River Engineering for Highway Encroachments Part one (1).
