Sentence examples for landform positions from inspiring English sources

The distribution of soil organic carbon (OC) in the landscape shows high variability between landform positions.

The persistence of OC in the landform positions could be designated by the proportion of 14C content of the bulk soil OC.

Therefore this work points to the necessity of monitoring the OC pools in these landform positions and to consider quick responses when it comes to changes in the hydrologic regime and/or land-use system.

The objective of this study is to estimate the net soil loss and gain at points with various land use types and landform positions in a small watershed in the Sichuan Hilly Basin of China by the 137Cs tracing technique.

Our data revealed that the amount of OC stored in the topsoil is mostly determined by land use, but subsoil OC stocks highly depend on landform position.

The procedure adds several measures of relative landform position to the previous classification of Pennock et al. (Geoderma 40 (1987) 297 315; 64 (1994) 1 19).

The properties that continue to show a clear relationship to landform position are largely remnant properties (e.g., depth to bedrock or to the C horizon), whose pattern reflects a stronger hydrological and/or pedological control.

The combination of geomorphic aspects with highly detailed soil data based on 16 soil profiles along a catena allowed us to closely examine the relationship between soil OC and the factors of landform position, soil inherent properties and grassland vs. cropland land use.

Landform elements have been classified based solely on consideration of their local surface shape, on consideration of a combination of surface shape and slope gradient, and on consideration of a combination of surface shape, slope gradient, and contextual measures of relative landform position.

At the ith perspective, U G i points from the camera position ( {boldsymbol{X}}_{C,i}^G ) to the landform position ( {boldsymbol{X}}_L^G ).

Based on particle size distribution, abrupt particle size change between silty deposits and underlying materials, the shape and microtexture of quartz grains, chemical and geochemical data and geochemical homogeneity of silty deposits from different landforms and geomorphic positions, the silty deposits appear to be wind-blown in origin and are classified as loess.
