The Urban Watersheds Research Institute is proud to present a workshop and training seminar on:

STORM WATER DETENTION AND RETENTION DESIGN

When: Two consecutive workdays in March 2009 from 8:30 a.m. to 5:00 p.m. Dates to be announced

(Please arrive between 8:00 and 8:15 on the first day to register and have your software installed)

Where:   To be announced.

Cost: To be announced.

CEU’s:     You will be eligible to receive 1.6 CEU’s or 16 PDH’s for this course.

What You Will Learn:

Urbanization always increases stormwater runoff and potential for floods. Stormwater storage facilities help to mitigate the potential hazards caused by this increased runoff. In this course you will learn:

1) hydrologic principles,

2) layout of detention basin,

3) sizing and design procedures using modified FAA method,

4) hydrograph routing method for estimating detention volume,

5) pre-shaping of detention basins and developing grading plans,

6) sizing and design of outlet structures, and

7) performance evaluation using reservoir routing.

Course Coverage:

The lectures and work sessions are designed to teach how to design a storm water detention system using the latest version of the computer model, UD-DETENTION. This model consists of eight Excel sheets developed for:

1) calculating the required storm water detention volume,

2) estimating the basin geometry using triangular, rectangular, or elliptical detention basin shapes,

3) developing the final stage-storage relationships, and

4) conducting reservoir routing through the basin being designed.

The outlet structure can consist of multiple orifices, weirs, risers and culverts. The design procedures used in UD-DETENTION comply with the design protocols recommended for urban areas, including the Denver metropolitan area. The workshop sessions provide hands-on operations and use of the various pond design techniques in UD-DETENTION and guidance on how to prepare the input parameters and how to interpret the computer outputs.

Software (Installed on Your Personal Laptop) and Laptop Computers Provided:

A limited number of laptop computers will be available in the classroom. You are encouraged to bring your own Laptop if it is loaded with Excel 97, or higher, and Windows 98 SE, or higher operating system. Needed software package(s) will be provided for installation. Please indicate on the registration form if you will bring a laptop, or will need one provided.

Instructors:

James C.Y. Guo, PhD and P.E. is a professor at University of Colorado at Denver. In addition to teaching engineering hydrology and hydraulics since 1982, he is active in applied research and is a practicing engineer. Dr. Guo’s research work has been referenced in number of City and County drainage manuals in United States and he brings to the class cutting edge technology in street hydraulics and storm sewer design.

Ken MacKenzie, P.E. is a Senior Project Engineer at Urban Drainage & Flood Control District. He is the author of the UD-Detention spreadsheet model.  He has eleven years experience in urban drainage design and construction of such projects and has taught this class with Dr. Guo over the last two years. 

BMPs will participate as guest lecturers, ensuring a rewarding experience for those attending the seminar.

The size of the classroom will be limited to provide more direct contact with the instructors. To assure a space, fill out the accompanying enrollment form and send it to the address on the form as early as possible.
