How would you measure the slope of a beach using ranging poles, a tape measure, and a clinometer?

To measure the slope of the beach accurately using ranging poles, a tape measure, and a clinometer:

1. Place one ranging pole vertically at the starting point (e.g., low tide mark).
2. Place a second ranging pole vertically a set distance (e.g., $5 \text{ m}$ or $10 \text{ m}$) up the beach, using the tape measure to ensure the distance is accurate and horizontal.
3. Hold the clinometer at eye level against the first ranging pole and sight towards the same eye level mark on the second ranging pole.
4. Read the angle of the slope directly from the clinometer.
5. Repeat this process, moving the first pole to the position of the second pole, and placing the second pole further up the beach, until the entire transect is measured.
