COURS.

APERÇU

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

• Understand the basics of stormwater management, pond design, application and types of storage facilities
• Understand the limitations of the standard of practice and examine the 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 learn to design and analyze stormwater ponds to meet given planning objectives

Description
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. You will learn how to integrate innovative solutions to address current and future challenges in stormwater management, ensuring that the systems you design are efficient, cost-effective, and sustainable.

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

Who Should Attend
Those involved with the design, construction, operation, maintenance, or review of stormwater ponds, including:
Drainage Engineers • Municipal Engineers • Consultants • Technologists • Developers • Planners • Supervisors • Field & Technical personnel

Special Features & Requirements
The course notes will be provided in electronic format.

Please download and install the following information:

• EPA-Stormwater Management Model (SWMM) Software: https://www.epa.gov/water-research/storm-water-management-model-swmm
• Environment Canada databases are available through this link https://climatedata.ca/explore/variable/?var=idf/
• IDF Data - Environment Canada has made some changes to 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: https://www.canada.ca/en/environment-climate-change/services/water-overview/quantity/monitoring/survey/data-products-services/explorer.html
• 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.
