HYDROLOGY TOOLS SET (HTS)

  Hydrology Tools Set (HTS) includes a suite of tools that have been developed through a collaborative research effort of Canadian Rivers Institute (CRI), University of New Brunswick (UNB), Agriculture and Agri-Food Canada (AAFC) and Environment and Climate Change Canada (ECCC). The suite of hydrology tools have been developed as part of a larger research effort aimed at evaluating the impacts of agricultural production practices on groundwater and surface water quality and on the quality of downgradient aquatic ecosystems.

  The various tools included in the suite can be used for advancing the understanding of local and watershed scale hydrology, such as stream hydrograph separation, water balance (e.g. evapotranspiration, drainage, infiltration, aquifer storage, etc.), soil moisture dynamics, crop water deficit and excess, crop irrigation requirements, etc. The tools included in the suite can be used in many areas of environmental research, such as the assessment of the impact of agricultural practices, urbanization, climate change etc. on surface water and groundwater.

  All the tools included in HTS have been developed using several principles as follows:

  • User-friendly interface
  • Streamlined and easy to follow procedures
  • Customisable parameters
  • Minimal input data requirement
  • Required input data generally available to the public at large
  • Offer a choice of methods when possible
  • Freely available (i.e. tool available at no cost and without user registration).

ETCalc

  ETCalc is a tool that integrates several customizable methods for calculating daily Potential Evapotranspiration (PET), Reference Evapotranspiration (ETR) and Actual Evapotranspiration (ET) based on user provided meteorological data and crop coefficients. The tool provides various output and data visualization options through a user-friendly interface and a streamlined process.

SepHydro

  SepHydro is a tool that offers several customizable filtering algorithms for performing hydrograph separation (or baseflow separation) and assessing surface runoff and groundwater contributions to streamflow based on user provided daily streamflow data. The tool provides various output and data visualization options through a user-friendly interface and a streamlined process.
