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.

Town of The Blue Mountains

On behalf of the Town of The Blue Mountains, we would like to thank you and your organization for your specialized technical support in a peer review capacity over the past four years… Your team not only provided timely review of all drainage related features of development applications but introduced updated municipal design criteria addressing changing climatic conditions. By unraveling the weather factors that impact snow melt potential, your team has helped the Town better understand how to be proactive in developing sustainable infrastructure.

Your team’s support assisted in keeping Town’s development projects moving forward efficiently. In addition to this, the review and introduction of updated municipal design criteria and construction standards addressing changing climatic conditions, continues to ensure the Town of The Blue Mountains fulfills its mandate for sustainable development.
