Soil geomorphology of the eastern Sevilleta Long Term Ecological Research Site
<p>Soils in the arid to semi-arid piedmont landscapes of central New Mexico were examined in order to evaluate surficial processes and landscape evolution in the central Rio Grande Rift. These soils were found to contain key information regarding pedologic and geomorphic responses to climate …

Soil-Geomorphology and Soil-Stratigraphy in the Lower Pomme De Terre River Valley, Southwestern Missouri
… 1962 to 1977, studies of surficial geology and soil geomorphology in the Breshears Bottoms along the lower Pomme de Terre River, Southwestern Missouri, produced models of erosion, deposition and soil-stratigraphy. These studies chronicle events that began prior to 50,000 radiocarbon years before …

Biogeomorphology and soil geomorphology of small semiarid basins, northeastern Arizona : influences of topoclimate and climate variations
… by characterizing vegetation, measuring soil thicknesses and estimating erosion rates. In contrast to south-facing, more xeric slopes, north-facing, more mesic slopes have substantially thicker mantles, less exposed bedrock and the greatest tree and herbaceous cover. On the more …

Topografian, maaperän ja geomorfologian vaikutukset putkilokasvien biomassan vaihteluun oroarktisella tunturikankaalla
… In this thesis I examine the effects of soil properties (soil moisture, temperature, pH and calcium), geomorphological processes and topography on the small scale variation of aboveground vascular biomass. I also compare two biomass variables: the dry weight of a biomass sample and the …

Late Quaternary semiarid eolian system dynamics : distribution, timing, and soil geomorphic controls, Black Mesa, northeastern Arizona, USA
… Mesa. Chapter 3 describes the role of advanced soil profile development on the stability of eolian systems; a factor generally overlooked by researchers interested in quantifying the relative activity of sand dunes. Appendix A contains the results of tests that determine the efficacy of samples …

Fluvial processes, beaver activity, and climate in the greater Yellowstone ecosystem and rock type control on hillslope morphology and soil development in the Sandia Mountains, New Mexico
… 3 explores the role of rock type in hillslope soil formation and slope morphology in the Sandia Mountains of New Mexico. Resistant rock types have a profound impact on slopes by increasing the amount of coarse colluvium that traps and preserves eolian material. Accretion of eolian material …

Pedogenesis on the Sefton Coastal Dunes, NW England
… the use of pedo-properties to identify dune soil system responses to environmental change on the Sefton coast, based on the development of conceptual pedogenic models. Previous environmental change and shoreline dynamics are determined through O.S. maps and aerial photographs, while present …
