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 6 pm Eastern Time

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

  • Apply new techniques to enhance the protection of life and property from flood damage.
  • Select computer software for application in flood control and urban drainage design
  • Strengthen your skills in flood control and urban drainage system design
  • Understand the limitations of the standard of practice and examine the state-of-the-art engineering
  • Gain a solid understanding of water quality design principles and criteria

After a brief refresher of basic hydrology, this course focuses on the practical application of sound planning and design practices, specific stormwater management techniques, and 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 review pond layout components, such as forebays, permanent and active storages, inlets, outlets, and spillways.

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.
