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

Intact Centre on Climate Adaptation

The Intact Centre on Climate Adaptation (ICCA) is a national applied research centre that focuses on mobilizing practical and cost-effective solutions to address climate change and extreme weather events. To this end, the ICCA is an incubator of new adaptation ideas, conducting research, knowledge mobilization and promoting initiatives aimed at de-risking the negative impacts of a changing climate and extreme weather. One of ICCA’s concerns is a growing uninsurable housing market in Canada relative to sewer backup.
 
ICCA believes the advanced technology and features of the SafeSump system can be instrumental to mitigating basement flood potential.  I have one of the first prototypes of the SafeSump system installed in my home. I have interacted directly with the start-up founder. I view him as entrepreneurial and passionate, and have met other members of his team with whom I was similarly impressed.  I am also familiar with Greenland Consulting Engineers, and congratulate SafeSump Inc. on their choice to create a joint “SafeSump” venture with Greenland.
 
ICCA looks forward to a supportive relationship with SafeSump Inc. upon the larger scale availability of their much-needed technology.

Landrex

Landrex is currently working with Greenland and business partner, Clearflow Group, to develop strategies to improve the functionality of stormwater management facilities in Landrex's (ie the City's) existing and future communities in North St. Albert, namely within the Erin Ridge North neighbourhood.

Landrex has been impressed with the collaborative and innovative approach that Clearflow and Greenland provide; they are a solutions-based group that are tremendously attentive, responsive and client focused. We believe they would be an extremely valued partner to the City of Saint Albert and represent the qualified, licensed, and professional consulting firm that the City so seeks.
