1.15.5.a. Rise and Fall Method

Try these first

1. 1.

   What is a back sight reading?

   Hint

   Think about how it helps us establish the elevation.

2. 2.

   What does a rise indicate in levels?

   Hint

   Consider the relationship between two points.

3. 3.

   What happens to the staff reading when it's placed at a higher point?

   • Increases
   • Decreases
   • Remains the same

   Hint

   Consider the relationship between height and readings.

4. 4.

   True or False: The Rise and Fall method is used exclusively for flat ground.

   • True
   • False

   Hint

   Think about the method's applications.

5. 5.

   You have a benchmark at 50m. If you measure a rise of 4m, followed by a fall of 3m, and then a rise of 2m, what is the final RL?

   Hint

   Keep track of your additions and subtractions systematically.

6. 6.

   In a leveling project, you noted the following staff readings at different stations: 2.0m, 5.0m, and 3.0m with a starting RL of 100m. What are the elevations at each of these stations?

   Hint

   Pay careful attention to the differences between readings at each station.
