A road engineer is looking for ways to improve safety on a stretch of road bordered by a moderately steep field of small boulders. Suggest and describe three techniques that could be used practically.
  What will be an ideal response?

Question 2

You are hiking and come across a curious sight. To your left is a firm, rocky slope angled downward toward you. To your right are trees, which are pointed toward the slope at an angle. What would you conclude? What produced the effect?

Answer to Question 1

ANSWER: A successful answer will include three of the following:
- The engineer could use heavy-duty metallic fencing or netting to hold the bottom part of the slope in place.
- A barrier of high-strength concrete or shotcrete could restrain the boulders more effectively.
- If the conditions are right, rockbolts could be used to anchor the deep part of the slope to the barrier in front.
- It may be worthwhile to see if water in the slope is increasing the danger and provide drainage.


Answer to Question 2

ANSWER: Here is a sample response:
I am in an area that was the top of a rotational slump. The material to my right was the head of the slump area, which rotated inward, changing the angle of the trees to point toward the slope.
A successful answer should
- identify the cause using the term rotational slump and
- correctly explain the cause of the angle of the trees.
