TRAINING.

Overview

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. 

Requirements and Special Features
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.
