  • Instructor


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):

10:00 am to 6:00 pm Eastern (Will include the usual breaks)

After attending this course, you will be able to:

  • Strengthen your skills on urban drainage system design
  • Apply your knowledge of basic hydraulics to drainage design problems
  • Develop a better understanding of technical design issues by focusing on related planning and environmental impact considerations
  • Apply your learnt techniques to enhance the protection of property owners from flood drainage and reduce pollution at a lower cost

To design an effective urban drainage and stormwater management system, knowledge of the technical design principles for each component of the system is required. After a brief refresher of basic hydrology, this course focuses on the practical application of sound planning and design practices for a wide range of stormwater management design techniques and infrastructure types.

Case studies will be presented to demonstrate, in practical terms, the pros and cons of alternative strategies, how to avoid pitfalls and the characteristics of successfully designed systems. The uniqueness of this course is its emphasis on hands-on exercises for designing the various components of drainage and stormwater management systems.

Please download and install the following information:

  • Environment Canada databases are available through this link Please create a shortcut on your desktop that contains this link
  • Environment Canada stream gauging database HYDAT:

  • Please test the installed software. When it opens do you see a map of Canada with a lot of green dots? - If yes, then you have been successful. - If no, then please open a File Explorer and go to the folder where the EC Software was installed. Typically this will be C:/Program Files (x86)/EC/ECDataExplorer/Support. In this folder will be a program from Microsoft, AccessRuntime.exe. Please run this program to install a Microsoft Access Database viewer that is used by the Environment Canada Data Explorer. Test the Data Explorer again to confirm that the map of Canada and the green dots appear. If they appear the program has been successfully installed. Please have available; a scientific calculator or Excel, a printed copy of the 3 slides per page presentation and a printed copy of the workshop examples.
