Description:

This four-day workshop provides a detailed introduction to urban drainage design. Design guidance for solving basic problems encountered in urban drainage design is provided. The topics are hydrology including rational equation, and synthetic hydrographs; storm drain systems, energy and hydraulic grade lines, detention ponds, and storm water management.

By participating in this workshop, you will focus on the practical application of sound planning, design, construction and maintenance practices for drainage systems. The designed components include storm water facilities design, open channels and culverts. An understanding of the hydrological and hydraulic principles that underlie practical design will also be developed. Hands on working examples will be presented to demonstrate in very practical terms the pros and cons of alternative strategies, the pitfalls that can be avoided, and the design features that characterize successful installations. The uniqueness of this workshop is its emphasis on hands on exercises for designing the various components of drainage systems. You leave with the confidence that not only you understand the concepts but also you can apply the knowledge to your projects.

After Attending This Course You Will Be Able To:

  • Understand the basics of storm water sewer system design and application
  • Back an analysis of existing systems for any possible problems
  • Learn how to use the commercial package CulvertMaster, FlowMaster and Storm CAD
  • Discover the numerous issues to consider when planning highway drainage systems at a given site
  • Learn to design highway drainage systems to meet given planning objectives
  • Determine runoff (peak flows and volumes) from urban watersheds
  • Apply basic hydraulic principles to urban drainage design
  • Perform roadway drainage designs using various roadway inlets
  • Size and/or analyze storm drain conveyance systems
  • Establish the energy and hydraulic grade lines for storm drains
  • Gain a solid understanding of drainage design, along with an increased confidence in the results of your design calculations

Who Should Attend:

This workshop will benefit anyone involved with drainage systems design and review, the construction, design or design review of storm water drainage systems, street, highway and storm water detention systems.
  • Including municipal, geotechnical, structural, road, drainage, mining and forestry engineers, developers, planners, consultants, supervisors,
  • and other technical personnel responsible for drainage facilities, open channels and culverts.

IN HOUSE AND ONLINE TRAINING

While both In-House and Online training can present with cost-effectiveness and time-efficacy, there are some very specific differences between in-house courses and those based online.
The demand for additional courses by individuals or groups of people is increasing. Still, it depends entirely on the preferences of a person what type of training he or she wants to receive. Online courses and in-house training carry some similarities but they are considered to exhibit some very pivotal differences too. Despite that, both types of learning can be really beneficial for attendees.
