Unit 4: How to use the velocity plank

In this unit, you’ll learn about the velocity plank, how to use it, how to read the results, and what to keep in mind when using the tool. Once you have completed this unit, you should have a clear understanding of what the velocity plank is, the kind of information it provides, and how to use it effectively to calculate stream velocity and discharge. This unit consists of 6 lessons, and a quiz at the end to test your knowledge of what you have learnt. 

By the end of this unit, you’ll be able to:

• Know how and where to use the velocity plank 
• Be knowledgeable of the safety concerns you need to consider before using the velocity plank
• Calculate the stream velocity and discharge 
• Interpret/make meaning of the results 

This course is designed for anyone interested in learning how to use the velocity plank effectively understanding its purpose, proper use, and how to interpret its results. As one of the more complex citizen science tools, the velocity plank involves both fieldwork (measuring depth and velocity) and desktop analysis (calculating discharge). It’s important to be clear about your objectives when using this tool, given its comprehensive nature.
