Description
Designing effective urban drainage and stormwater management systems requires a comprehensive understanding of hydrology, hydraulics, and design methodologies. Participants will begin by refreshing their knowledge of basic hydrological concepts, which form the foundation of drainage and stormwater design. The course then delves into the intricacies of stormwater management, focusing on essential criteria like runoff calculations, rainfall analyses, and the design of open channel flows. By exploring alternative green infrastructure designs, participants will learn how to incorporate sustainable practices into their projects.

The course provides a detailed examination of various stormwater management techniques, guiding participants through designing and selecting appropriate facilities, understanding hydrological methods, and leveraging advanced drainage software. Special emphasis is placed on real-world applications, including case studies highlighting different stormwater strategies' pros and cons. Participants will be equipped to tackle common design challenges, from runoff control to erosion mitigation and stormwater treatment.

Participants will gain hands-on experience with real-world examples and software tools in the final sessions, reinforcing their learning with practical applications. By the end of the course, attendees will be able to confidently design and review stormwater systems, produce and evaluate design reports, and apply innovative practices to protect against flooding.

Who Should Attend
This course is ideal for professionals involved in designing, planning, and managing urban drainage and stormwater systems.

Municipal engineers, environmental consultants, urban planners, and technical personnel responsible for water resources will significantly benefit from the in-depth exploration of hydrologic and hydraulic principles. Developers, regulatory officials, and project managers overseeing sustainable urban development projects are encouraged to attend, as the course offers valuable insights into stormwater best practices.
