Q

Beach-Profile Analysis - Purpose (3)

A
  1. Used to measure the transverse profile of a beach (shape and morphology) from a fixed point.
  2. Can be used to compare to illustrate and quantify changes in height, width, volume and shape.
  3. Can be used to show relationships between profile and other factors (rock type, sediment size or shape)
