The aim of this paper is to study dust deposition patterns over various topographic configurations. Dust patterns are analysed for different combinations of hill size and hill spacing, and comparisons are made with the reference profiles over
identical but isolated hills. The study is, of course, restricted since the total number of topographic combinations is unlimited, but the landform combinations investigated were selected such that, if topographic interference plays a significant role
Quantitative topographic method of fault morphology recognition
A quantitative method for morphology recognition of topographically expressed faults is developed. The method is based on the analysis of digital elevation models (DEMs). Kh mapping correspond mostly to structures like strike-slip faults, while
The AA. study the influence of 9 local, non-local and combined quantitative topographic characteristics on vegetation cover, altitude and density in 4 areas of the Rudny Altai. Differentiation of plant properties is shown to depend on relief
parameters which control migration and accumulation of water in landscape by gravity. In some cases the phytocoenosis characteristics can have higher correlation with non-local and combined topographic variables than with local ones. The AA. demonstrate
the advisability of the use of digital models and maps of indicated topographic characteristics in plant investigations.
Correlations between DEM-derived topographic indices and remotely-sensed vegetation cover in rangelands
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
disturbance to the pavement cover, if not too extensive, can also be repaired by this mechanism. The cross-surface flux of stones also represents a powerful smoothing agent, lowering topographic highs and filling topographic depressions. The results presented
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
for different models of glaciation for different areas with particular regard to topographic forms and glacial history is proved.
This article first provides some rudimentary background in fractal geometry. Next, the various methods that have been proposed to determine fractal dimensions for both linear features and topographic surfaces are presented and evaluated. Whether
are settled areas chosen to typify landscapes of their region. Statistical measures of access availability are derived from topographic maps for five levels of access rigor.
/floodplain flow. Specifically changes in the specification of the floodplain topographic surface and the upstream boundary condition are considered for two flood events.
and postglacial development of valley systems. The morphology of mixed-type valleys is highly persistent, as it had developed before and was maintained during the Upper Pleistocene. The topographic position of these valleys and their fills can be used
The features of morphometry and sedimentology of 54 debris flow fans in semiarid subtropics of southwestern China are summarized here based on field surveys, interpretations of aerial photographs and measurements of topographic maps. The influence
