Figure 1.13 A topographic chronosequence in South Wales. (a) The coast between Gilman Point and the Taff estuary.
The sand spit has grown progressively from west to east so that the cliffs to the west have been longest-protected from
wave action. (b) The general form of the hillslope profiles located on Figure 1.11a. Cliff profiles become progressively
older in alphabetical order, A–N.
