Comprehensive Review of Culvert, Open Channel and Storm Sewer Design
Introduction
Comprehensive Review of Culvert, Open Channel and Storm Sewer Design
Introduction
Changes in land use affect urban drainage and, therefore, present challenges for engineers who must deal with drainage planning, runoff analysis, storm sewer hydraulics, and watercourse drainage within the government regulations. The course focuses on these topics, providing participants with a comprehensive understanding of culvert, open channel, and storm sewer design, and allowing designers already in the field to update their knowledge.
The course will also address the use of computer software for design work.
After participating in this course you will be able to do the following:
- Consider technical issues in design by focusing on related planning and environmental impact
- Enhance the protection of property from flood damage and reduce pollution at a lower cost
- The select computer software that is most suitable for your application of urban drainage design
- Participate in public consultation meetings with confidence
- Employ design methodology learned in the course on your next project for urban drainage
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.
Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
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.
