Workshops in USA & Canada
2-Day Training Workshops for PCSWMM/SWMM5
CHI offers 2-day training workshops in many locations across the U.S.A. and Canada.
Each workshop provides the time-limited PCSWMM/SWMM5 software and is designed to help you become proficient with the modeling packages. In two days of hands-on workshops, you will learn the latest version of the PCSWMM graphical decision support system, as well as the internals of the latest version of the Stormwater Management Model (SWMM5). The PCSWMM software (included with the workshop, together with all documentation and instructional materials) is time-limited and an appropriate license must be purchased later to maintain the software subscription, which includes unlimited support for 12 months.
1-Day Advanced Training Workshops for PCSWMM/SWMM5
CHI offers 1-day Advanced training workshops on the second day of all 2-day training workshops across the U.S.A. and Canada.
Designed with the experienced PCSWMM user in mind, the 1-day Advanced training course builds on previous PCSWMM experience to sharpen and enhance your software experience. Included with PCSWMM training is a 60-day workshop license of our latest version of PCSWMM Professional 2D. This new release of PCSWMM provides an integrated approach to 2D modeling, allowing the user to seamlessly transition between 1D and 2D modeling.
By user request, an optional LID schedule has been added to the Advanced workshop. Learn how to apply lot-level and watershed scale LIDs, and how to model a variety of applications which include permeable pavement, boulevard planters, rainwater harvesting, infiltration trenches and vegetative swales.
Additional Advanced topics include, but are not limited to: importing from HEC-RAS, assigning dry weather flow patterns, dual-drainage modeling, RDII analysis, radar rainfall, rainfall duration curve analysis and calibration. Additional tips and tricks are also presented that showcase how to use the software to generate enticing graphs, profile plots and reports.
In the U.S.A. and most of Canada, the workshops will be conducted in English using the English version of the software.
In Canada, throughout the province of Quebec, workshops may be conducted in French using the French version of the software (without Desbordes hydrology). Upon special request, workshops may also be conducted in French in other locations.
For additional information regarding workshops conducted in English, please contact CHI directly.
The Modeling Programs
PCSWMM* is CHI's comprehensive, GIS-based, graphical decision support system for SWMM urban drainage modeling (sanitary, storm and/or combined systems). It is a fully-featured urban drainage system modeling package, with no limitations on model size or complexity, includes a complete, smart GIS engine (no 3rd party licenses required), tailored to urban and non-urban drainage, and provides native support for a large number of GIS formats, as well as powerful topological operators and querying. PCSWMM provides advanced versions of all standard urban drainage modeling visualization techniques, including animated hydraulic and energy grade line profiles, plan-view thematic coloring, powerful and flexible graphing, dry weather flow pattern generation, parallel computing, as well as on-the-fly statistical uncertainty, sensitivity, calibration and error analyses. It automatically maintains standard SWMM5 models from GIS data and synchronizes in both directions, thus providing complete data compatibility with all other SWMM5-based software tools.
PCSWMM goes beyond the current crop of modeling tools to ensure users have a deep knowledge of the underlying model processes, to increase user competence and confidence. It adds radar-rain, time-series analyses, design storm generation, rainfall disaggregation, dual-drainage, real-time control and many other utilities. Please refer to our PCSWMM web pages for more information.
* PCSWMM is proprietary software owned by CHI and was written in Canada.
Developed by the US EPA, the Stormwater Management Model (SWMM) is an open-source, comprehensive model for continuous and single-event simulation of runoff quantity and quality for stormwater, sanitary and combined sewer systems. It can model: dynamic storms; pollutant build-up, washoff and transport; infiltration and inflow; dynamic routing; surcharging, surface flooding; storage ponds; storage treatment; diversions; pumping stations; various BMPs and LIDs; and much more. Established and continuously developed for 40 years, SWMM is simple to run, and is used effectively on small as well as large studies. PCSWMM always incorporates the latest release of SWMM5.
With over 5000 licenses, PCSWMM has been the leading decision support system since its inception in 1984 (or as FastSWMM since 1977). Applied in tens of thousands of sewer and storm water studies throughout the world (over 50 countries), typical applications of PCSWMM include:
- design of drainage systems and their components for flood control
- sizing of detention facilities and their appurtenances for flood control and water quality protection
- designing control strategies for minimizing combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs)
- evaluating the impact of rainfall-dependent inflow and infiltration (RDII) on SSOs and sewer backups (water-in-basements, WIBs)
- dual drainage (major/minor system) modeling and design, including dynamic interaction of dual systems
- evaluating global optimal and/or passive real-time control (GO RTC) operational strategies
- flood plain mapping of natural channel systems
- integrated catchment/watershed management modeling, including rural areas, river systems, urban sewer systems, treatment plants and receiving waters
- generating non-point source pollutant loadings for waste load allocation studies
- evaluating the effectiveness of best management practices (BMPs) and/or low impact developments (LIDs) for reducing wet weather pollutant loadings
- evaluating strategies for NPDES Permits, CMOM and TMDL requirements
Participants supply their own lap-top computers, and the software is sent to participants ahead of the workshop (unless local desk-top computers are being used, and the software uploaded by the instructors - please see location specific details below). Each workshop will run from 8:00 am to 5:00 pm daily. Lectures will be followed by hands-on exercises allowing you to explore the different aspects of the package. Participation in the Workshop earns 1.5 CEUs. Content may vary slightly from the topics listed below.
