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

After participating in this course, you will be able to:

  • Understand the basics of storm water design and application
  • Understand limitations of the standard of practice and examine state of the art engineering
  • Apply basic hydrology and hydraulic principles to urban drainage design
  • Determine runoff (peak flows and volumes) from rural and urban watersheds
  • Gain a solid understanding of stormwater pond design principles and criteria
  • Learn to design and analyze stormwater ponds to meet given planning objectives

This workshop provides a detailed review of the complex stormwater management pond design procedures. By participating in this course, you will focus on the latest application of sound planning, design, construction and maintenance practices for stormwater management ponds.

The workshop will cover a review of the building blocks of a pond design, such as hydrology and hydraulic calculations that underlie a design. It will provide an overview of the current criteria required by approval agencies, and a review of pond layout components, such as forebays, permanent and active storages, inlets, outlets, and spillways.

Course Outline

Please download and install the following information:

  • Environment Canada databases are available through this link
  • IDF Data - Environment Canada has made some changes for the IDF data. Note for everyone; the link can be placed in a shortcut on the desktop to allow for easy access.
  • Please test the installed software. When it opens do you see a map of Canada with a lot of blue dots? - If yes, then you have been successful.
  • 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.
