Sand dune succession theory

WebbShape of sand dunes To measure the angle of a slope between two points, you need two or three people. Identify a slope unit between two breaks of slope. Measure this distance. Person A stands at the bottom of the slope with the clinometer resting on top of a ranging pole. Person 8 holds a second ranging pole at the top of the slope.
