Integrated Science and Watershed Management System (ISWMS™)

Welcome to the Home Page for the “Integrated Science and Watershed Management System”. This site provides updates about our ecosystem database and decision support analytical tool.

The Integrated Science and Watershed Management System (ISWMS™) was originally developed by Greenland in 2003 as a windows-based Decision Support System (DSS) for stormwater management; hydrological (continuous rainfall and design storm events) modeling; and, Canadian climate flood forecasting capabilities. The ultimate DSS ‘vision’ also included (depending upon the availability of certified open data and timely evolution of new operational platforms) other science-based analytical tools and integration with current Internet and GIS technologies. The ultimate ISWMS™ development goal is to include multi-functional stormwater management; hydrologic; water quality; nutrient trading; hydraulic and contaminant transport; flood forecasting; climate change impact; instream biological health assessment; and, Best Management Practice (BMP) analysis capabilities for river and lake basin management programs and to provide accurate information for water supply, wastewater treatment and flood control infrastructure planning and design initiatives. Greenland is well on its way to achieving the DSS vision!   

In 2003, Greenland was retained to develop the initial version of ISWMS™ as a flood forecasting tool for the 3,200km² Nottawasaga Valley Watershed, located north of Toronto (Canada). It was also used to prepare Subwatershed Management Plans in Southern Ontario. In 2005, Greenland began work on the next ISWMS™ phases, including, an ESRI-GIS operational platform that was integrated with a daily water balance, nutrient and sediment loading model (called CANWET™) and which would also be maintained by the Greenland Group. In 2006, the ISWMS™ program added new technical support partners affiliated with Canadian and U.S. universities. These independent scientists would later assist Greenland as a “science advisory team” for future software phases. The science advisory team has included faculty and researchers from the University of Guelph, University of Waterloo, University of Victoria and Trent University (in Canada), and a U.S. team affiliated with Penn State University.

  • Lake Capacity Modeling Tool (Proposed in 2017/18)
  • Low Impact Development Platform (Proposed in 2017/2018)

Since 2003, ISWMS™ and key components (incl. CANWET™) have been used by the Greenland Group for many public sector, public-private partnership, land development and natural resources projects. The projects were also undertaken by qualified Greenland professional engineers and scientists and included:

  • The international award-winning Lake Simcoe Protection Plan (Canada) that was prepared by the Province of Ontario with local First Nations and other partners;
  • Assessing water use stresses within the 15,000 km² Trent-Severn Rivers Basin (Canada) and as part-of a multiple partner Source Water Protection Program;
  • Watershed characterizations and water budget assessments for Source Water Protection Projects by Ontario’s conservation authorities and other stakeholders;
  • Urban growth impact assessments (i.e. water supply, wastewater treatment and master drainage planning focus) and identification of viable infrastructure servicing solutions;
  • Evaluation of existing and future nutrient loads with mitigative options and using an ecosystem target and cost-benefit approach for priority catchments in the Lake Erie and Lake Winnipeg Basin; and,
  • Developing new stormwater management, master drainage planning, flood mitigation and watercourse crossing design standards that had regard for regional climate change factors.   

In 2013, the Greenland Group expanded its software team to include internationally renowned industry partners from Canada, United States and Europe. Thank-you for your interest in the Integrated Science and Watershed Management System (ISWMS™) by the Greenland Group.

Walton Development and Management

The Walton Group of Companies is a multinational real estate investment and development firm concentrating on the research, acquisition, administration, planning and development of strategically located land in major North American growth corridors. With nearly 90,000 acres of land under administration including 22 development projects, Walton is one of North America’s premier land asset managers.

Walton Development and Management L.P. (“Walton”) has retained Greenland International Consulting Ltd. (“Greenland”) to assist with our municipal infrastructure planning and engineering design for several new communities in the County of Simcoe, Ontario including environmental assessments and water resource analysis. Greenland is highly regarded in the industry for their professional approach to the environmental aspects of these projects and state-of-the-art decision support tools (such as CANWETTM) to address climate change adaptation, cumulative watershed impact, and adaptive management such as post-construction performance monitoring. Greenland’s business model is unique and has provided Walton with value-added deliverables through the use of best available science and solution-based methodology. This includes forming a landmark public/private sector phosphorous reduction program to protect a sensitive fishery habitat system within headwaters of the Nottawasaga River Basin for one of Walton’s projects in Simcoe County. Greenland’s CANWETTM model and other in-house stormwater management and climate change impact assessment tools were instrumental for Walton to establish long-term partnerships in this community, including the local municipality, Nottawasaga Valley Conservation Authority and other key stakeholders.

County of Simcoe

Greenland provided exemplary consulting services to complete this landmark project. The firm’s attention to detail and proactive ideas was very important to assist the County in addressing the issues of concern about the study’s findings and also providing defendable, yet provocative, solutions based on best available science and proven technologies for the benefit of all local municipalities.

This letter confirms that the study objectives were met within the approved time frame. Greenland also provided a sizeable in-kind contribution to complete value-added deliverables and established new partnerships in terms of future watershed modeling and technology development initiatives involving the County of Simcoe.

Sustainable Buildings Canada

Sustainable Buildings Canada (SBC) has worked closely with Greenland Consulting Engineers (Greenland) as part of the Savings By Design program offered by Enbridge Gas Distribution. The program features an integrated design workshop that exposes builders and developers to the potential environmental and energy performance benefits that can be achieved through a holistic planning process. This includes identifying alternative approaches to site sustainability including low impact development and storm water management.

Inherent in the integrated design process is the need to access experienced and highly qualified individuals and organizations that can identify potential alternative solutions. SBC has a very capable roster of consultants that represent the core expertise required for this kind of expertise. Greenland is one of those organizations, providing critical input related to storm water management, low impact development and site sustainability.

Greenland consulting staff are all extremely knowledgeable and up to date on the various issues related to storm water management and low impact development and have always provided that expertise in a professional manner, recognizing the need to be sensitive to both the needs of the developers and the desire to improve environmental performance. It has been a great pleasure to work with Greenland and we look forward to doing so in the future.
