To assess the impact of varying material strength, the SCAPE model
was run with the extracted profile over a further 5 ka simulation period
(unless otherwise stated). For these runs, all input conditions remained
constant as stated in Table 1. This includes the material strength of the
cliff face,with the exception of the anomalous layer introduced to assess
its effect; the characteristics of which are summarised in Table 2 for the
various simulations. The material strength of the remainder of the cliff
has been determined based on previous experience with SCAPE and
set to represent a cliff with an equilibrium recession rate of 0.7 m/yr.
