Terracettes in the western Iowa Loess Hills were characterized morphogenetically, with field observations suggesting high association with ungulate activities. A new class of mega-terracette is recognized that characterizes study-area forms orders
Effects of vegetation and slope aspect on water budget in the hill and gully region of the Loess Plateau of China
Precipitation, throughfall, stemflow and soil water content were measured, and interception, transpiration, evaporation, runoff, deep percolation and soil water recharge were estimated in the natural Liaotung Oak forestlands in the hill and gully
in the district. The use of Hg and other metals as tracers associated with mining activities suggests that long-term rates of floodplain sedimentation in the Cid district were less than half as high as those in the nearby Gold Hill district. This suggests
that the intensity of land disturbance in the Cid district was less than in the more intensively mined Gold Hill district.
Soil seed bank composition and distribution on eroded slopes in the hill-gully Loess Plateau region (China): influence on natural vegetation colonization
of basement fault-blocks after the formation of layer A. A relatively rapid uplifting of the Xilingang hill after formation of layer B is highlighted. The 3 layers are all cut off by a NNE trending normal fault with a fault-throw of 53cm, suggesting
, a switch from hay to silage and a shift in summer grazing from the hill ground to the inbye. Both farming and crofting areas have seen a fall in cattle numbers and sheep numbers peaked prior to 2000, but in general land use has been more stable in farmed
at patch, hill slope transect and small watershed scale from 1998 to 2006. Soil samples were taken from field for the determination of cesium-137 and SOC contents. Vegetation cover change from 1998 to 2006 at the small watershed scale was assessed using
A morphometric analysis on the badlands has highlighted that these landforms formation and distribution are primarily related to the steepness of the hill flanks, which favour runoff and gravitational processes, along with favourable aspects
