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.

Interdisciplinary Centre on Climate Change

We are pleased to write in full support of the Canada-Europe Partnership, particularly the collaboration of the Interdisciplinary Centre on Climate Change (IC3) and the
Partners for Action (P4A) network to support incorporation of climate change considerations in the project and assist in testing FLOODVIEW with Canadian municipalities and insurers.
 
P4A and IC3 are dedicated to consideration of climate change in Canada’s approach to flood risk management, and dissemination of knowledge and best practices to the insurance industry, government decision-makers, and the Canadian public. We look forward to partnering with you to identify effective solutions to minimize urban flooding.

Six Nations Council

On behalf of the Environment Office of the Six Nations of the Grand River, we would like to thank Greenland International Consulting Limited for the work completed to prepare the Master Drainage and Flood Remediation Plan (MDFRP) for the McKenzie Creek watershed. This plan has now enabled our office to identify the flood prone residences throughout the watershed with the flood plain mapping that has been prepared as part of this assignement. We appreciate the role that Greenland has played in assisting our office in directing Public Works with prioritizing the remedial projects to be completed in the flood prone areas. 

We also appreciate Greenland's effort in assisting the Six Nations of the Grand River with the preparation of funding applications to secure the resources to complete these remedial works. We are convinced that this MDFRP can be used as a template for completing similar drainage and flood remediation works both locally and in other First Nations lands. 

We look forward to working with your company again in the near future on the remaining watersheds that need this important work done. 

Thank you for your ongoing assistance.
