• Core simulation model used is GWLF, which has been substantially enhanced over last 10 years (now GWLF-E)
• Initial modeling application developed using ArcView 3.x GIS software (AVGWLF)
• AVGWLF has been used by PaDEP and a number of other government and research organizations since 1999.
• Efforts to re-configure application to work in non-commercial GIS platform (MapWindow) began in 2010.
• First “official” version of MapShed set to be released to public by end of May 2011.

….then use MapShed to derive input data for the GWLF-E model

Can use either GWLF-E or PRedICT to estimate load reductions from BMP implementation

Evans Penn State Institutes of Energy and the ... demo2.pdf•Core simulation model used is GWLF, which has been substantially enhanced over last 10 years (now GWLF-E)](https://reader033.vdocuments.mx/reader033/viewer/2022042415/5f2ff6dff173ac29f456f5c2/html5/thumbnails/10.jpg)
Specify various BMP settings for a given scenario, and then run PRedICT to estimate potential load reductions . . . .

Similar estimates of BMP reductions can also be simulated via use of the “Edit BMP Data” option in the GWLF-E model…..

…but use of BMPs within GWLF-E model allows more options , and does better job of simulating flow changes (particularly with urban BMPs)
