Description :
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 and erosion models as indicators of moisture redistribution and soil loss or accumulation in the landscape. The spatial patterns shown by these indices are compared with the observed distribution of vegetation cover obtained from satellite imagery.
