The digital model of erosional topography takes into account changes of tectonic movements in space and time, changes of humidity and lithology within the area which is set up by digital matrix of elevations. Experiments with the model on a computer
A fifteen year history of coastal dune recession at Magillan, has revealed both time and space contrasts in processes and morphology. Since 1968 storm frequency has increased, while dune retreat reached a peak in 1978-1979. Three types of dune
Remote sensing data sets of snow are being studied and refined for input into energy balance, hydrological, and general circulation models. Snow influences the amount of solar energy retained and returned to space, the utilization of radiant energy
to a sediment input which was particularly variable in time and space. Although mining has now virtually ceased, it will continue to have an impact on the physical landscape well into the twenty-first century.
