Abstract This paper presents a quantitative account of vegetation–environmental factor relationships in arid rangelands. Vegetation cover was recorded using Braun-Blanquet combined abundance-cover scale in each quadrat. Within each quadrat, one profile was dug and soil samples being taken at 0-20cm and 20-100cm depths. Under study physical-chemical characteristics included texture, lime, orga...

The use of derivatives in geomorphometry is reviewed. For first and second derivatives (slope and curvatures) of the land surface, represented by a square-grid DEM, use of a quadratic based on nine points is recommended. For detailed analysis of slope gradient, maximum slope (based on two points) may be useful: but only if the DEM is very accurate. For curvature, streamline (rotor) curvature sh...

Nine indicators, including slope, engineering rock group, slope structure type, distance to road, topographic relief, fault, water system, vegetation cover pr...

Relegated to the margins of large body research on ADHD and school is individuals’ own retrospective accounts schooling. Drawing multiple narrative interviews with nine young adults in Sweden, present study explores their experiences reflections concerning years compulsory school. Despite variations gradient decline, time was described as a slippery slope, rapid deterioration secondary Particip...

Existing interrill erosion equations based on mini-plot experiments have largely ignored the effects of slope length and plot size on interrill erosion rate. This paper describes a series of simulated rainfall experiments which were conducted according to a randomized factorial design for five slope lengths (0.4, 0.8, 1.2, 1.6, and 2 m) at a width of 0.4 m, five slope gradients (17%, 27%, 36%, ...
