Refraction modelling. (a) Comparison of first-arrival picks
with modelled first-arrivals using a commercially available non-linear op-
timisation routine to obtain the optimal subsurface velocity distribution.
(b) Continuous velocity model that gave rise to the modelled arrivals in (a).
The interpreted bedrock depth of between 10 and 13 m was verified by a
borehole.
