Slope‐control on the aspect ratio of river basins
Terra Nova, 2009 AbstractAlthough it is traditionally thought that drainage basins are geometrically similar, we present new results which indicate that the aspect ratio of weakly dissected river basins at large scales (10–103 km2) depends on the surface slope: steeper surfaces develop narrower and lengthier basins whereas more gently dipping surfaces develop more ...

The Effect of DEM Resolution on Slope and Aspect Mapping
Cartography and Geographic Information Science, 1991This article examines the effect of the spatial resolution of digital elevation models (DEMs) on slope and aspect data. After a review of computing methods for slope and aspect and such factors as DEM resolution, topographic complexity, and quality of DEM data, the article presents two experiments using DEMs from 8 to 80 m intervals.

A New Digital Slope-Aspect Display Process
Cartography and Geographic Information Science, 1990Maps displaying variations in slope-aspect across a surface such as the physical landscape are commonly created from digital elevation model data, in the form of regular or irregular surface tesselations. Computed slope-aspect azimuths are normally assigned to the aspect class within which the azimuth falls, and each aspect class is colored differently

Influence of Slope Gradient and Aspect on Soil Organic Carbon Content in the Region of Niš, Serbia
Sustainability, 2021 Topography-induced microclimate differences determine the local spatial variation of soil characteristics as topographic factors may play the most essential role in changing the climatic pattern.

Ecological Modelling, 2008 The slope and aspect of a vegetated surface strongly affects the amount of solar radiation intercepted by that surface. Solar radiation is the dominant component of the surface energy balance and influences ecologically critical factors of microclimate ...

Quantitative slope aspect determination
Journal of Hydrology, 1971Abstract A rapid and efficient method is described for quantifying slope exposure using only a T-square and triangle on a topographic map. Results of aspect determination using this technique on a small Wisconsin watershed are compared with those obtained by point sampling.

Effect of slope length, aspect and phosphogypsum on runoff and erosion from steep slopes
Soil Research, 1991The efficiency of phsophogypsum as an amendment for controlling erosion on embankments was studied on a Typic Rhodoxeralf soil, with 48% slope and 10 and 1.5 m long plots, with western and northern aspects and a westerly dominant wind during rainstorms.

Some Aspects of Submarine Slope Stability
1982This paper critically summarizes existing methods for analysing marine slopes under wave and earthquake loadings. Static limiting equilibrium, static deformation, liquefaction, and full dynamic analyses are summarized. Methods for analyzing the effects of underconsolidation in rapidly accumulating or gaseous sediments are described.

Geomorphological aspects of slopes in mudrocks of the United Kingdom
Quarterly Journal of Engineering Geology, 1981Introduction A marked convergence of interest has characterized geomorphological and engineering investigations of slopes during the last decade or so. The former have combined traditional geomorphological mapping with recently developed remote sensing methods to identify and classify stable and unstable slopes, while examination

Using vertices of a triangular irregular network to calculate slope and aspect
International Journal of Geographical Information Science, 2021Terrain derivative calculations from triangulated irregular network (TIN)-based digital elevation models (DEMs) have been extensively explored in geomorphometry.
