Filters. (geography) A geographical technique in which the angle of a beach is measured with a ranging pole and a clinometer. noun.

What is beach gradient?

Shingle beaches typically have a steep gradient (over 10˚) because the waves easily flow through the coarse, porous surface of the beach, decreasing the effect of backwash erosion and increasing the formation of sediment into a steep sloping back.

How does longshore drift affect pebble size?

Pebble size is related to both wave energy and longshore drift direction. The smaller material is carried by the process of longshore drift to be deposited down-drift. On the contrary, high-energy waves will remove all but the largest and heaviest beach material.
