PCSWMM & EPA SWMM5 Workshop

Overview

It is becoming increasingly difficult to dismiss snowmelt as a negligible occurrence, considering shifting climate patterns and increasing regulatory/permitting expectations. In northern communities, snowpack accumulation and melt have a meaningful effect on annual water budgets, stormwater routing, pollutant loads, and infrastructure resilience. This specialized workshop provides participants with a comprehensive introduction to simulating snow accumulation and melt processes within EPA SWMM5 and the tools within PCSWMM to help build the model and interpret results. It is designed to equip participants with practical skills to confidently apply cold-region hydrology in your modeling efforts to comply with emerging legislation, adapt to climate-impacted hydrology, and provide defensible, full-season continuous simulation and water-budget assessments.

This workshop will begin by reviewing the fundamentals of snow hydrology with an emphasis on understanding the data needs and resources available to prepare and quality-check results. Participants will be guided through the setup, calibration, and analysis of a snowmelt-driven runoff model in SWMM5. Attendees will work with real-world examples to define snowmelt parameters and test their sensitivity to impacts on snowmelt contributions to runoff. Guidance will also be given on interpreting model outputs, troubleshooting common issues, and integrating snowmelt analyses into common modeling applications.

During this course, attendees will have an opportunity to learn from an experienced engineer during this online training event. Through presentations, demonstrations, and hands-on exercises, attendees will understand the relevant analytical procedures, the capabilities and limitations of PCSWMM and EPA SWMM5, and develop the necessary skills and confidence to undertake snowmelt modeling.

Instructors

This workshop will be led by one or more of the following instructors:

Ellen Arrowsmith, P.Eng.

Ellen has 5 years of experience in the water resources and climate risk sectors. Her experience modeling for stormwater analysis and design spans both rural and urban environments with a focus on low-impact development, flood risk assessment, and floodline mapping. Ellen specializes in automating water resources modeling tasks and analysis through scripting. Prior to joining CHI, Ellen worked as a consulting water resources engineer and as a product manager in the machine learning industry, with a focus on climate risk modeling.

KAT FINNEY, B.Sc.(Eng), M.Sc.(Eng), P.Eng.

With over 10 years of experience working as an engineer for CHI, Kat has extensive experience with watershed models for a variety of applications including real-time flood forecasting, LID investigations and integrated 1D-2D model analysis. She has conducted many training workshops across North America, South America, China and South Africa on PCSWMM and EPA SWMM.

MICHAEL GREGORY, M.Sc., P.Eng., PE

Mike has over 30 years of experience in water resources planning, analysis, design, program financing, and policy development. He has developed hydrologic and hydraulic models for over 100 stormwater analysis and design projects and specializes in continuous simulation for water balance calculations, nonpoint source water quality loading, sizing of sediment removal and rainwater harvesting facilities, and assessment of watercourse and wetland impacts. He has also assisted with the development of and technical support for stormwater modeling software. Mike has been a lead author and researcher for many peer-reviewed technical papers and publications, and has presented and lectured at conferences, seminars, training workshops and universities world-wide.

DIEGO A. PAEZ, Ph.D., P.Eng.

Diego has over 7 years of experience in water supply and storm water modelling and management as well as over 3 years of experience in coastal and fluvial risk assessment and mitigation. His expertise includes using hydroinformatic tools to solve problems in municipal infrastructure modelling and design, transient analysis, fluvial and coastal flood risk profiling and mapping, and hydraulic modelling of pipeline systems. He has delivered undergraduate and postgraduate courses at Universidad de Los Andes (Colombia) and at Queen’s University (Canada) and has instructed workshops in North and South America. Diego has over 10 peer-reviewed scientific publications and over 15 international conference publications and presentations.

NANDANA PERERA, Ph.D., P.Eng.

With more than 15 years of consulting engineering experience, Nandana specializes in water quantity and quality modeling in stormwater/sanitary systems and watershed modeling with different focuses including dual drainage, low-impact development, flood analysis and 1D-2D integrated modeling. He has conducted a number of training workshops across North America on PCSWMM and EPA SWMM and is continuously working on training expansion into Sri Lanka and India.

HAILIANG SHEN, Ph.D., P.Eng.

Hailiang is a licensed professional engineer in Ontario with over 10 years of experience and has expertise in modeling for various applications. Prior to joining CHI in 2017, Hailiang was a water resources modeling specialist with GHD. He has applied modeling techniques for various hydraulic structures design analysis and environmental assessment studies. His expertise includes 1D, 2D, and 3D hydrodynamic and water quality modeling for riverine/lake systems, hydraulic modeling for stormwater, and sanitary sewer systems. He has developed techniques to couple automated model runs with optimization algorithms to enable efficient sensitivity and calibration studies. Hailiang has working knowledge of the following modeling packages: PCSWMM, InfoWorks ICM, TUFLOW, RMA2/RMA4, CE-QUAL-W2, EFDC, Delft3D, TELEMAC-2D/3D, InfoWater, EPANET, Bentley Hammer, and has developed over 60 tools in 10 programming languages for model pre- and post-processing. Hailiang has published over 15 scientific papers and acts as peer-reviewer for three technical journals.
