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

Description
This course begins with a brief refresher on basic hydrology before diving into the practical application of effective planning and design practices. It covers specific stormwater management techniques and offers a detailed review of the complex procedures involved in designing stormwater management ponds. Participants will learn about the latest practices in planning, design, construction, and maintenance of stormwater management systems.

We will provide an in-depth look at the fundamental components of pond design, including hydrology and hydraulic calculations. It will also give an overview of the current criteria required by approval agencies and examine key pond layout components such as forebays, permanent and active storages, inlets, outlets, and spillways.

Additionally, case studies will be presented to illustrate, in practical terms, the pros and cons of various strategies, how to avoid common pitfalls, and the characteristics of successfully designed systems. This comprehensive approach ensures that participants gain both theoretical knowledge and practical insights into effective stormwater management.

Who Should Attend
This course is ideal for professionals involved in the design, construction, operation, maintenance, or review of stormwater ponds.

It is particularly beneficial for drainage engineers, municipal engineers, consultants, technologists, developers, planners, supervisors, and field and technical personnel. Participants will gain valuable insights and practical skills to enhance their expertise in managing stormwater systems effectively.
