Activity 4.2: Contour Mapping (A-Frame, Water Level)
1) Construct either an A-frame or a water level.
The A-frame is by far the easier tool to construct. The water level is more useful for measuring through thick vegetation and more than a few feet at a time. Watch the following video to learn how:
- How to build and use an A-frame level (~3 minutes)
- Learn how to Make a Bunyip Water Level with Brad Lancaster (~11 minutes)
There are, of course, many other videos out there if you want to search. 1 2
2) Mark a contour line on your design site.
After you have completed your tool, head outside and find a site for a potential swale or path. With flags or stakes mark a contour using the tool you created. Take pictures to share.
3) Complete your assignment by submitting answers to the following questions. Then please share a copy via this week's Participant Forum: Contour Mapping.
Snap a picture of your work along with a commentary that briefly answers the following questions:
- What was your experience building the device you chose?
- Where and why did you cite your contour line?
- How easy or hard did you find mapping contour? Was the line where you thought it would be?
- What potential do you envision for using this technology?
