What You Will Learn:    
The Colorado Urban Hydrograph Procedure (CUHP) is a unit hydrograph based software that was calibrated to urban rainfall-runoff data in a semi-arid hydrologic region of eastern Colorado.  It has been used since the late 1970s and was re-calibrated in 2016.  It has been tested many times to show that it produces reasonably accurate results in transforming rainfall to surface runoff. The CUHP software has been updated and modified over the years and in its current Excel-based form provides considerable flexibility to the user.  

In this class you will learn about CUHP's Excel-based software, it's evolution and how to use the latest version of the software to link the CUHP-generated hydrographs to EPA SWMM for hydraulic routing as they as they are conveyed through the stormwater system or channels, pipes, detention, etc.  CUHP Excel spreadsheet provides for linkages with EPA SWMM and allow the two programs to run simultaneously from the Excel spreadsheet.  This allows the user to run various design storms and land use condition scenarios in a batch mode without the need to repetitively run each modelling scenario separately, thereby saving much time for the user.

You will learn how to use both CUHP and EPA SWMM software in a workshop format .  In addition, you will learn the nuances of how to best represent the flow routing elements in EPA SWMM to obtain most accurate end results.  The instructors of this class conducted an extensive evaluation of problem areas in how various routing element parameters are represented in EPA SWMM and how they contribute to significant errors in final results if not properly used in the model. They will share with you their experience and you will learn how to properly code in various routing elements in EPA SWMM to achieve most accurate results in planning projects.  

Computers:  
Bring your own laptop.  Obtain copies the latest version of CUHP and EPA SWMM 5.1  (links available at http://udfcd.org/software) and install them on your computer before coming to class.  It is critical that you do that if you are bringing your organization's computer since your IT departments will often not permit you to install software without their permission.  
 
Faculty: 
Derek Rapp, P.E., CFM, is the president of Peak Stormwater Engineering, LLC, and specializes in hydrologic and hydraulic modeling.  He has 11 years of consulting experience and is versed in many technical modeling platforms.  He has worked closely over the years with UDFCD to update and modify many of their software programs to keep pace with current technology and updated hydrologic and hydraulic research.  He recently rewrote the CUHP software code to allow it to run exclusively in an Excel spreadsheet and provided a direct link with EPA SWMM to allow the two programs to run simultaneously from the Excel interface.  This automated link allows the user to run various design storms and land use conditions quickly without the need to repetitively link each interface file.          

Ben Urbonas, P.E., D.WRE
, is the president of the Urban Watersheds Research Institute. Before retirement from the Urban Drainage & Flood Control District in Denver, Colorado (District), he managed the Master Planning Program there for over 30 years.  In early 1970s while working for a consulting firm, he developed a computer version of the Colorado Urban Hydrograph Procedure.  Most of the computational algorithms of that software are still in the current version of CUHP.  While at the District he led the development of protocols that permitted hydraulic routing of the CUHP-generated hydrographs using UDSWM (an earlier version of SWMM used by District) and also using the current version of EPA SWMM (updated since then by Derek Rapp).  He is the author of over 100 technical papers, has co-authored two books dealing with stormwater detention and BMPs and has contributed to a number of other books, including two national manuals-of-practice on stormwater facilities design and stormwater quality.  He brings much practical experience and expertise related to the use of hydrologic modelling and the planning of complex stormwater systems.

Colorado is a great place to visit!

Colorado is a great place to visit in May before the major tourist season begins. There a many outdoor recreational activities such as rafting, hiking, fishing, photography, sight seeing, etc. Also, the City of Denver and its metropolitan area has many attractions and great restaurants.  So, if you come and attend this class, you may want to extend your stay and take advantage of this most attractive area of the United States.

The size of the classroom will be limited to approximately 24 students.  To assure a space for yourself we suggest registering early by clicking on the "Register Now" button above.
