Element 3: Evaluate Water Changes
Materials:
6 Water change overlays generated in Skill 1, Element 10
1:24,000 scale Mumper topographic map
drafting tape
Exercise:
1. Tape the three "1982" overlays onto the 1:24,000 scale topographic map.
2. List at least two observations about the distribution and abundance of the three water modifier types.
3. Tape the three "1988" overlays onto the 1:24,000 scale topographic map.
4. List at least two observations about the distribution and abundance of this date’s water modifier types.
5. Tape the two "Temporary Water" overlays onto the 1:24,000 scale topographic map.
6. List at least two observations about the distribution and abundance between the two dates for this water modifier group.
7. Tape the two "Seasonal Water" overlays onto the 1:24,000 scale topographic map.
8. List at least two observations about the distribution and abundance between the two dates for this water modifier group.
9. Tape the two "Semi-permanent Water" overlays onto the 1:24,000 scale topographic map.
10. List at least two observations about the distribution and abundance between the two dates for this water modifier group.
11. Tape the "1982 Temporary Water" Overlay and the "1988 Seasonal Water" overlay onto the 1:24,000 scale topographic map.
Did any Temporary Water in 1982 become Seasonal water in 1988?
Any observations about how many water bodies changed and where?
12. Tape the "1982 Seasonal Water" overlay and the "1988 Temporary Water" overlay onto the 1:24,000 scale topographic map.
Did any Seasonal Water in 1982 become Temporary Water in 1988?
Any observations about how many water bodies changed and where?
13. Tape the "1982 Semi-permanent Water" overlay, the "1988 Temporary Water" overlay, and the "1988 Seasonal Water" overlay onto the 1:24,000 scale topographic map.
Did any Semi-permanent Water in 1982 become Temporary Water or seasonal water in 1988?
Any observations about how many water bodies changed and where?
