Please note, This instructor-led course has specific dates and times:
This course is held online over 2 days on the following schedule (All times in Eastern Time Zone): 10 am to 3 pm Eastern (Will include the usual breaks) Participants are expected to have some elementary technical knowledge of engineering principles. Notes will be provided in electronic format. Please have a standard engineering calculator with scientific functions, a laptop with Microsoft Windows, an MS Excel spreadsheet, or equivalent. The course includes a comprehensive list of reference material available on the Internet from government and non-government organizations.
After participating in this course, you will be able to:
- Solve simple hydrology and hydraulic engineering problems
- Analyze hydrology, hydraulics and the service life of culverts
- Review culvert inspection condition reports
- Develop strategies for effective maintenance and repair of culverts
- Understand regulatory requirements and standards related to culvert design and inspection
Description
Culverts are a critical component of our drainage system which protects people and property from the damaging effect of floods. The assessment and review of culvert designs and condition reports are vital components of effective asset management. These functions ensure that resources are used efficiently, maintenance is properly planned, and culverts continue to provide reliable flood protection.
This course is designed for managers, reviewers, technicians, and inspectors seeking a foundational understanding of culvert design, installation, and inspection throughout their lifecycle. It covers essential concepts without involving complex mathematical formulas. The course features lectures with real-life examples, straightforward hands-on exercises, and problem-solving activities.
Who Should Attend
This course is designed for engineers, managers, reviewers, technicians, and inspectors who are not familiar with hydro-technical engineering.
It is suitable for civil engineers, mechanical engineers, mining engineers, agricultural engineers, municipal engineers, manufacturers of drainage products, general contractors, property managers, directors of physical plants, municipal officials, infrastructure inspectors, field review personnel, project engineers, and others who wish to gain more knowledge about hydro-technical systems or need a refresher.

INSTRUCTOR
Senior Project Manager | Water Resources
Nav is a Senior Water Resources Engineer with 20 years of experience.
He has extensive experience in stormwater management and drainage planning and design throughout Canada, ranging from servicing /planning studies to detailed design of complex systems. His stormwater infrastructure design experience includes storm sewer systems, culverts, above and below-ground detention and water quality facilities, diversion structures, control and outfall structures, infiltration systems, rip-rap protection works, and instream rehabilitation works. He’s also experienced in base-flow augmentation, source control/rainwater management and other LID systems-relatively new techniques that support sustainable design.
His stormwater engineering knowledge, municipal development, and highway experience make him an excellent resource for a range of clients. He has also provided expert opinions and reports on legal proceedings related to drainage throughout BC.
