Computational Methods in Stormwater Management
The topics presented in this short course represent a comprehensive array of hydrologic and hydraulic tools for stormwater management design, detention facility design, and subdivision planning. The Virginia Tech/Penn State Urban Hydrology Model (VT/PSUHM) will be used to illustrate how these tools can assist in the design of stormwater management facilities. Special emphasis will be placed on the fundamental calculations for detention facility design, particularly outlet structure design. The Multiple Stage Routing Model (MSRM) in the VT/PSUHM will be used to assist in understanding the design process. Additional emphasis will be placed on BMP design, particularly enhanced detention, enhanced extended detention, bioretention cells and infiltration basins. Example analysis and design situations will be addressed and solved using the software. The participants will be guided through practice problems that deal with stormwater management design.
By attending this short course, participants will receive information that will help them navigate Pennsylvania's Stormwater permitting process. Attendees will also be more knowledgeable about designing stormwater management practices to meet the Post-Construction Stormwater Management Requirements in Chapter 102 regulations.
Participants must bring a laptop computer to this short course. The user must have administrative rights to the computer so that the VTPSUHM software can be installed. A time for advanced software installation is provided on Wednesday evening, August 6, between 7:00 and 9:00 p.m. at the Best Western Plus East Mountain Inn & Suites (room to be determined). Only MS Windows–based laptop computers will be supported, using Windows XP, Windows Vista, or Windows 7. Microsoft Excel 2003 or 2010 is also required. The laptops should have viewing screens from 14 to 17 inches. Apple computers, notebook computers, iPads and similar devices will not be supported. Laptops can be shared with a colleague if so desired.
Who Should Enroll
This course is intended for stormwater facility designers with previous exposure to urban runoff calculations involving NRCS (SCS) methods, channel and reservoir routing principles, and Rational methodologies. Because hands-on computer work is emphasized in the course, the fundamental concepts behind these methods will not be presented in great detail. However, specific details for each of the methods presented will be documented or referenced in the supplemental short-course notes. Each participant is encouraged to bring a hand calculator for occasional use.
Each attendee will receive course handout materials that include a set of notes documenting standard stormwater computational methods, speaker presentation notes, and a copy of the VT/PSUHM version 8.0 program.

Professional Development Hours
The Commonwealth of Pennsylvania has recently enacted a law requiring Professional Engineers and Professional Land Surveyors licensed in Pennsylvania to complete 24 hours of continuing education during each two-year license renewal cycle as a condition of renewal. The Pennsylvania State Registration Board for Professional Engineers, Land Surveyors, and Geologists has developed and published a set of proposed rules to implement the provisions of the law. Participation in this program will award you 16 PDH units.
Continuing Education Units
Continuing Education Units (CEUs) are based upon a standard of 1 unit per 10 hours of classroom instruction. Upon completion of this program, each participant will be awarded a certificate for the CEUs earned during this program, for a maximum of 1.6 CEUs.

The Computer Model
The VT/PSUHM is written in Visual Basic for operation under Microsoft Windows. The program provides for the transfer of VT/PSUHM output to Microsoft Excel and Microsoft Word. The program contains 23 interactive modules organized under five sub-menus as follows:
- Utility modules: CN weighting, travel-time calculations, hydrograph addition, graphics plotting, swale design, circular pipe normal and critical depth calculations, basin-empty calculations, and storage volume of pipe on a slope.
- Rainfall modules: U.S. Weather Bureau, Maryland, Pennsylvania Penn DOT PDT-IDF (1986) and Publication 584 (2008), and Virginia rainfall distributions; SCS type II and III rainfall distributions; and manual hyetograph entry.
- Runoff modules: NRCS unit hydrograph, NRCS tabular hydrograph, Rational hydrograph, and manual hydrograph entry.
- Routing modules: Muskingum channel routing, modified Puls reservoir routing, MSRM, and ProBasinDesigner. MSRM is a design tool that allows engineers to configure up to ten stages in a complex outlet structure to meet a variety of peak discharge and water-quality target releases and manual input of outlet rating curves. ProBasinDesigner integrates several of the MSRM design modules into one streamlined module for the design of a basin for multiple events.
- Surface profile module: Standard step-method backwater calculations.
Because of the history and nature of the software, copies of the VT/PSUHM will be issued only to participants who attend all two days of the short course. The VT/PSUHM is not freeware (copyright Penn State 1984–2014, Virginia Tech 1995–2014) and was developed primarily for educational purposes. During its thirty-year existence the software has never been available for purchase. It has always been distributed as a teaching aid in this short course. The participants and their co-workers are welcome to use the software in private practice if they so desire. However, Penn State policy does not permit distribution of the software to parties who have not attended the short course. Any distribution beyond the short course remains exclusively the right of Penn State and Virginia Tech.
