Modifications in land utilization have a direct impact on urban drainage, posing challenges for engineers responsible for tasks such as drainage planning, runoff analysis, storm sewer hydraulics, and watercourse drainage, all while adhering to government regulations. This course centers around these specific subjects, offering participants a thorough comprehension of culvert, open channel, and storm sewer design. It also provides an opportunity for designers already working in the field to enhance and update their knowledge in these areas.

Course Objectives:

To discuss the future of computer-aided design in urban drainage Municipal engineers; developers; planners; consultants; hydraulic engineers; technicians and technologists; and other technical personnel responsible for drainage facilities, underground pipe systems, inlets, culverts, and catch basins. This course is particularly suitable for those who want a comprehensive review of drainage design methods.
To increase participants’ knowledge of the design process and design tools used in urban drainage.

Who Should Attend?

Anyone associated with the construction industry would benefit from this course. In view of the vastness of the sector, the following personnel would typically be able to gain immediate benefit from this course.
