Finally! Solving Stormwater Problems with HSPF Modeling - 2021


This course is the finale of our four-part HSPF Hydrology Webinar Series—others include Introduction to HSPF Continuous Simulation; PERLNDs, IMPLNDs, and RCHRESs; and HSPF Calibration and Validation. Save 20% and earn 4 PDH / 0.4 CEU with our full-series bundle!

While HSPF was not originally designed and developed to explicitly model stormwater problems, the program has the flexibility and complexity to represent almost any stormwater situation – large or small.

Join prolific speaker Doug Beyerlein (P.E., P.H., D.WRE) for this live, educational webinar to thoroughly examine how HSPF can be used to solve stormwater problems.

We’ll explore how specific PERLNDs, IMPLNDs, and RCHRESs can be used to model both stormwater problems and solutions. For example, we’ll see how you can create PERLNDs to represent green roofs or combine PERLNDs with IMPLNDs to model lateral flow dispersion and impervious area disconnection. We’ll also walk through the process of constructing RCHRES FTABLEs to represent stormwater retention and detention facilities as well as different LID features (e.g., bioretention and permeable pavement). We’ll close the loop on continuous simulation with HSPF by discussing how you can successfully model climate change impacts and other stormwater problems.

Learning Objectives 
Attendees can expect the discussion and education of the following learning objectives.

  • Learn how to set up and simulate different stormwater problems and solutions.
  • Learn how to adjust PERLND parameter values to model green roofs.
  • Learn how to connect IMPLND runoff to an adjacent PERLND to represent lateral flow dispersion or impervious area disconnection.
  • Learn how to set up RCHRES FTABLEs to represent stormwater retention and detention facilities.
  • Learn how to adjust meteorological time series data input to model climate change impacts.
