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

Moriyama & Teshima Architects

On behalf of Moriyama & Teshima Architects, I would like to thank you for your high level of competence and involvement expressed in the design process on the Keele Street Public School Addition and Renovation project… I felt you were integral and instrumental in coming in and taking the project from an ill-fated design…to design completion, tender and the approvals stage. You showed high levels of knowledge and understanding in your field, and your thoroughness and professionalism have led to the success of this project to date. I am thoroughly satisfied in the way you designed the services system, dealt with authorities having jurisdiction, and for your recommendations regarding budgetary concerns.

I would not hesitate in recommending you as a civil engineering consultant on any further project I am involved with.

Township of Adjala-Tosorontio

As Chief Administrative Officer for the Township of Adjala-Tosorontio, I would like to commend Greenland on their successful completion of the Everett Secondary Plan Master Servicing Plan and Class Environmental Assessment.
 
The level of service and timely delivery of all reports, analyses and correspondence was greatly appreciated by Township staff. Greenland’s innovative solutions and prompt responses to issues raised by the Town Staff Approvals Agencies and the affected public throughout the EA Process were very important, and we look forward to working with your team on future projects.

To that end, our team at the Township of Adjala-Tosorontio would be pleased to provide references for your firm on similar projects in future

City of Ottawa

On behalf of the City of Ottawa, we would like to thank Greenland International Consulting Limited, and in particular, Don Moss for his exemplary efforts in his role as Model Keeper for the City of Ottawa… Greenland has achieved a high level of confidence with Senior Staff and City Council as well Conservation authority and the Ontario Ministry of Environment… The City is appreciative of the new Modelling Tool developed by Greenland which will assist the City in conducting timely and efficient development reviews. The City will now be able to test proposed infrastructure with the overall development, determine changing impacts to existing infrastructure as ponds, as well as any changes to the receiving watercourses.

Don’s knowledge, dedication and professional approach over the past five years has been a crucial factor in the success of the project under very challenging circumstances.
