Comprehensive Review of Culvert, Open Channel and Storm Sewer Design

Calgary, Alberta /
Mar 11 - 12, 2019 /
Course Code: 09-0316-2362

  • Overview
  • Syllabus
  • Instructor
  • Location


After participating in this course you will be able to do the following:

  • consider technical issues in design by focusing on related planning and environmental impact
  • enhance protection of property from flood damage and reduce pollution at a lower cost
  • select computer software that is most suitable for your application of urban drainage design
  • participate in public consultation meetings with confidence
  • employ design methodology learned in the course on your next project for urban drainage

Changes in land use affect urban drainage and, therefore, present challenges for engineers who must deal with drainage planning, runoff analysis, storm sewer hydraulics, and watercourse drainage within the government regulations.

The course focuses on these topics, providing participants with a comprehensive understanding of culvert, open channel, and storm sewer design, and allowing designers already in the field to update their knowledge. The course will also address the use of computer software for design work.

Course Outline:

  • Rainfall Analyses
  • Time of Concentration: Review of Design Equations
  • Methods of Computing Rainfall Losses
  • Estimating Flows for Drainage Design
  • Examples of Estimating Flows
  • Basic Hydraulic Theory
  • Design of Open Channels
