Welcome to the CANadian Watershed Evaluation Tool (CANWET™ - Version 4.2)

INTRODUCTION

CANWETTM (v 4.2) is a GIS-based software suite designed to inform decision making around river basin and watershed management; water supply and wastewater treatment infrastructure; food security; and, climate change adaptation. Its ability to quickly estimate daily water balance, nutrient, erosion sediment, and bacteria loadings from GIS input data allows CANWETTM to serve as a powerful decision support system. 
 

This latest release of CANWETTM is VB.Net database-driven and web-aware, and features an integrated open source GIS environment. Its relative ease of use and ability to take advantage of commonly available spatial data makes it a solid choice over other continuous models with greater data input requirements. This "All-In-One" software suite allows you to begin your project without requiring expensive prerequisite software to use in tandem.
 

Since 2003, CANWETTM has been used for Assimilative Capacity Studies; Watershed and Sub-watershed Studies; Master Drainage Plans; Infrastructure Planning; and, Source Water Protection Studies. Various versions of the GWLF engine that is incorporated into CANWETTM have also been applied in numerous studies worldwide.


KEY FEATURES AND FUNCTIONS OF CANWET 4.2

©

CANWETTM (v 4.2) offers an extensive range of features and useful tools including:

  • Daily time-step simulation engine for hydrology, hydraulics and water quality.
  • Integrated and flexible charting and mapping of simulated output.
  • Comprehensive Beneficial Management Practice (BMP) routines.
  • Integrated hydraulic routing of in-stream water quality concentrations and flows.
  • Integrated climate change scenario analysis tools (including climate data).
  • Powerful web-based service for retrieval of useful datasets.
  • Modules to handle loading estimates from septic system and livestock contributions.
  • Routing of point source discharges.
  • Link simulated output back to GIS for map creation.
  • Resources to transform your CANWETTM GIS layers into Google Earth overlays.
  • Detailed Users' Guide and Technical Manual.

GIS Processing

CANWETTM allows the user to quickly and easily generate input data through Geographic Information System (GIS) clipping routines. Data is clipped from GIS vector and grid maps. The clipping routines are used to generate input data for single or multiple basin analyses.

GWLF Simulation Engine

The Generalized Watershed Loading Function (GWLF) is a continuous model based on land use categories. It simulates stream flow, sediment, nutrient (nitrogen and phosphorous), and fecal coliform loadings from catchments, given variable-size source areas (i.e. agricultural, natural, and urban/developed lands).

BMP Functionality

CANWETTM allows for the addition of beneficial management practices (BMPs) by applying area-weighted loading rate reductions for phosphorous, nitrogen, sediment, and animal coliforms for both rural and urban lands. Multiple practices can be added in parallel or in series. It also calculates estimated costs for typical BMP applications based on unit-costing.

DATA ANALYSIS

CANWETTM features several powerful output approaches to suit your needs.

CHARTING TOOLS

  • Multiple data series can be plotted simultaneously with dual axes.
  • Choose from Catchment output, Land use, Stream Routing, and Nutrient Routing dataset categories.
  • Charts can be custom labelled, formatted, and printed.

GRID OUTPUT

  • Grid data can exported in raw format to CSV format and imported to EXCEL for custom analysis.
  • Catchment output can be filtered by date, climate scenario, or theme (e.g. Hydrology, Nutrient Load Contributors, Sediment, Land Use etc.).

STREAM AND NUTRIENT ROUTING

CANWETTM calculates continuous constituent concentrations by reach for use in TMDL and assimilative capacity studies.

Client Testimonials

Mississippi Valley Conservation Authority

On behalf of the Mississippi Valley Conservation Authority, we would like to thank you and your consulting firm for your technical capacity in completing the CANWET model with baseline conditions in our watershed.

I have worked closely with Greenland Consulting Engineers (Greenland) over the past two years as part of this project. We also value your staff’s ability to troubleshoot issues and respond on time. Greenland’s commitment, thoroughness, and professionalism have led to the success of this project with the addition of a new routine to the CANWET software.

It has been a great pleasure to work with Greenland and we look forward to using your expertise again in the near future.

Communitech

The Greenland Group (Greenland) was introduced to Communitech in 2013. This letter is to acknowledge the importance of this proactive joint venture and to indicate our strong interest in future project partnerships with Greenland and other network members.

Greenland is now supporting other joint initiatives with Communitech. These leading-edge information technology partners will include other private sector members with the Communitech network, as well as Ontario government agencies and First Nation communities. These projects are intended to develop commercialized products and services involving the Greenland Group and other Communitech partners and to enable new Canada-wide related collaborations.

Mark, if any your prospective clients or contacts have questions regarding our collaborative efforts to date, ongoing discussions and project leveraging capabilities, the Communitech team would be more than happy to help.

We look forward to our continued strong collaboration with Greenland.

Town of Collingwood

I would like to recognize the active involvement of the GREENLAND Ground of Companies in the Town of Collingwood's economic development efforts and dedication to helping advance the Town's vision of being a specialized technology hub. Their extensive knowledge of the water technology and land development industries, coupled with their desire to help propel Collingwood forward as a regional economic leader, are very much appreciated. 

The Town is proud to have GREENLAND in the community as they have also been key supporters in facilitating introductions with renowned organizations, such as the University of Guelph, University of Waterloo, WaterTAP, Communitech, Canadian Water Resources Association and Canadian Water Network. These organizations and others will help Collingwood secure new businesses with a recreational and healthy lifestyle focus. GREENLAND is also a passionate supporter of youth networking and knowledge transfer initiatives, providing financial assistance for Collingwood Youth Centre initiatives at www.collingwoodyouthcentre.ca
