Innovative applications of laser scanning and rapid
prototype printing to rock breakdown experiments


Abstract

We present the novel application of two technologies for use in rock breakdown experiments,
i.e. close-range, ground-based 3D triangulation scanning and rapid prototype printing. These
techniques aid analyses of form–process interactions across the range of scales relevant to
breakdown (μm-m). This is achieved through (a) the creation of DEMs (which permit quantitative
description and aanalysis of rock surface morphology and morphological change)
and (b) the production of more realistically-shaped experimental blocks. We illustrate the
use of these techniques, alongside appropriate data analysis routines, in experiments designed
to investigate the persistence of fluvially-derived features in the face of subsequent
wind abrasion and weathering. These techniques have a range of potential applications in
experimental field and lab-based geomorphic studies beyond those specifically outlined here.
