the distribution of snowpatches at 2 topographically different sites, one previously glaciated and the other a young volcanic landscape that has remained unglaciated since the central caldera erupted, forming the basis of the present topography. The need

The topography surrounding the three study sites influenced both beam and net shortwave radiation through a shadowing effect, a terrain reflecting component, slope angle and aspect of the terrain, as well as the range of elevations within

This paper demonstrates some of the possibilities offered by GIS in arctic geomorphology. GIS is used for simulating the topography and volume of Pjetursson Glacier, Disko, Central West Greenland at different times in history. The volume found shows
good correspondance with volumes calculated from empiric formulas. An energy balance model is established in the frame of a rasterbased GIS. The model is used for demonstrating the significance of surrounding topography, on components in the energy
This paper examines the effect of topography on vegetation cover on the mountain ranges, alluvial fans and footslopes of drainage basins in arid central Australia. The AA. use the topographic indices commonly employed in distributed hydrologic
