Using Git and GitHub with R

R is free, open source software (FOSS) for general calculation, statistics, data processing and graphing. It is very widely used in hydrology and there are many packages of added functions developed by and for hydrologists.

One of these is the CSHShydRology package, which is being developed by members of CSHS/CWRA. The package is available at

To use the package and to contribute to its development, it is useful to understand how to use the program Git and the online service GitHub. However, Git and GitHub have steep learning curves, which can prevent them being used fully.

In this workshop, you will learn about:

  • The advantages of using version control software
  • Git, a version control program, which works with repositories on your computer
  • GitHub, a service used for hosting repositories online
  • How to work with Git and GitHub from inside R

After completing the workshop you will be able to install R packages from GitHub, use Git for version control on your own computer, and to contribute to the development of R packages, such as CSHShydRology.

This workshop is intended to provide an accelerated introduction to the Raven Hydrologic Modelling Framework.

Learn how to use the Raven Hydrological Modelling Framework , a flexible and user-friendly software tool for developing both simple and complex watershed models. Raven is currently used across Canada by practitioners, consultants, researchers, and organizations for flood and reservoir forecasting, climate change impact assessment, regional water resource planning activities, and research applications. It enables the user to customize their model to different landscapes in Canada, and contains a suite of diagnostic tools for assessing and improving model quality. The course will be instructed by James R. Craig, the lead developer of the Raven framework and the Canada Research Chair in Hydrologic Modelling and Analysis at the University of Waterloo.

By the end of the course, each participant should:

  • Have an improved appreciation for the capacity of Raven for flood forecasting, reservoir management, water budgeting, and transport simulation
  • Be able to apply, test, modify, and interpret simple models built with Raven and Raven-UBCWM
  • Understand the modelling workflow process , I/O, and basic implementation details
  • Have an understanding of the extended capabilities of Raven and understand the logistics associated with building and testing more advanced Raven models
  • Have an improved appreciation for the challenges of trustworthy model development

Flow Forecasting using WATFLOOD(R) and GreenKenue(TM)

This flow forecasting short course will feature a hands-on application of importing a GRIB2- format numerical weather forecast and applying it to a southern Ontario watershed after an introduction to the WATFLOOD® hydrological model and the National Research Council’s GreenKenue™ processor.  On completing this workshop and with the help of a detailed manual (download here) you will be able to carry out a forecast on a watershed configured for the WATFLOOD model.

Recent severe flood events in Canada have pointed out the need for accurate and timely flow forecasts to help evacuate threatened locations and mitigate flood damage by preventative measures. Over the past few years, high resolution numerical weather forecasts with up to two weeks lead time have become readily available. The distributed (gridded) hydrological model WATFLOOD™ and the pre & post processor GreenKenue™ have been coupled and configured for use in real-time streamflow forecasting applications. WATFLOOD® due to its gridded approach to hydrological modelling and routing can take full advantage of the equally detailed numerical forecast thus highlighting locations of concern in a watershed.

WATFLOOD® (WF) is free & open source. Green Kenue™ (GK) is free.

Workshop topics

  • Watflood overview and example of the 2019 spring forecast for a river in Southern Ontario
  • GK: Pre & Post processor for Watflood
  • GK: File formats, display capabilities
  • Outline of real-time data availability for flow (or flood) forecasting
  • Downloading in GRIB2 format:
    • RDPA – CaPA: CMC Regional Deterministic Precipitation Analysis (for hindcasting)
    • CMC Regional Deterministic Prediction System (RDPS) – 10 km
    • CMC Global Deterministic Prediction System (GDPS) – 0.24 X 0.24 degree resolution
  • Downloading the past month CWS recorded flows for streamflow nudging in the model
  • Processing sequence using WF programs to create WF readable GK format files for use by the WF model
  • Description of the WF files (event) setup for doing daily flow forecasts
  • Executing a forecast

 Understanding Indigenous Culture: Knowing Wampum as Woven Through the Ojibway Anishinaabe Tradition

Brian Charles is an off-reserve Band member of the Chippewas of Georgina Island and currently lives along the western shore of Lake Simcoe near the village of Hawkestone, ON.  He is working collaboratively with a small group of knowledge keepers to research and assemble a physical repository of wampum belts that document Ojibwa history. The presentation will illuminate how wampum was used to record not only relationships and treaties between the First Peoples of the Eastern Woodland, but also with settler societies in Canada.

 As we reflect on how to meaningfully respond to the Truth and Reconciliation Commission’s Calls to Action in Canada, this workshop provides a framework for creating a shared historical understanding of the relationships and treaties that have shaped our land and offers a model for how we can treat Indigenous and Euro-Canadian knowledge systems with equal respect.

This workshop is essential for those working in sectors that promote responsible, innovative, and effective water resources management. Past participants’ responses to this workshop have been overwhelmingly positive. The workshop provides an important framework for understanding our complex historical relationships, allowing for a better integration of traditional values and relationship requirements into our collective work.

 Enhancing engagement in Canadian water management: Involvement and collaboration with a broad range of stakeholders and authorities

This workshop is designed for those interested in designing and implementing collaborative approaches of engagement in water resource management.  We focus on two types of engagement, involvement and collaboration, with diverse stakeholders and authorities (including Indigenous rights-holders).

The themes of Water Week at Blue focus on collaboration and partnerships. As water management challenges have become more complex than ever before and diverse perspectives are increasingly prioritized, the ability to create spaces for deliberation and to effectively engage with stakeholders and authorities is vital to the success of managing activities and sustainably using water resources. Furthermore, involving communities and Indigenous rights-holders or partnering to share management responsibilities (collaboration) can be more effective at identifying problems early, generating innovative solutions to problems and reducing risks – if implemented well.

This workshop consists of a series of speakers and active participation that will build capacity for participants to implement meaningful engagement and move towards collaborative water management

First, speakers will share examples, lessons and frameworks for meaningful engagement from across Canada. Then, a stakeholder mapping exercise will allow participants to visualize their contexts, discuss opportunities for coordination and identify gaps in engagement (e.g., strategies to ensure all relevant interests and perspectives are represented at the table).

Lastly, a group backcasting exercise will reflect on current challenges, generate a desired vision and brainstorm specific actions towards enhanced collaborative water management for practical application in the workplace. Participants will receive templates for stakeholder maps and a follow-up report that summarizes workshop discussions.

 Indigenous Approaches & Engagement in Watershed Planning

Watershed planning has been undertaken in Ontario for many years, although recent policy changes and emerging ecological stressors have underscored its important role in the protection of water resources. A watershed-based approach to protection, restoration, and enhancement of interconnected natural heritage and water resource systems will typically require cooperation among municipalities, Conservation Authorities, Indigenous communities, and others. From an Indigenous community perspective, watershed planning can be a process of building partnerships, developing an understanding of the watershed, achieving consensus on a plan of action, and providing for implementation and adaptive management. This presentation proposes an outline of guidance for Indigenous watershed planning.
