Materials You Will Need:
1) Compass with clinometer
3) Sloped Surface
Note: Place your cursor arrow over the yellow boxes in most pictures for further explanations.
Step 1: Align Your Compass
CAUTION: Your compass markers and other compass features may be different from mine. However, they should be similar enough that these directions will work for any compass.
Step 2: Pour Water on Slope Surface
Pour the water on the sloped surface so you can see the exact way the slope is dipping. This ensures greater accuracy in the measurement.
Step 3: Place Compass Parallel to Water Flow
TROUBLESHOOTING: If your N symbol and clinometer are not in the same quadrant of the compass, you have your E and W symbols backwards. Just twist the compass dial 180 degrees to switch them.
Step 4: Read the clinometer
Step 5: Find the Direction the Slope is Dipping
To find the direction your slope is dipping:
1) Align your North symbol to true North.
2) Point your compass in the direction of your slope
3) Read the symbol on your compass to determine the direction
Record the direction as either N, S, E, W, NE, NW, SE, SW. In this case our slope is dipping in a South-East direction so we will choose SE.
NOTE: If, for example, the direction is only slightly off of East, you need to record the direction as East. The slope direction needs to be close to half-way between two directions to justify a SE, SW, NE, or NW.
