Quaternary landscape evolution, pedology, and geoarchaeology in central Texas.
Central Texas provides a unique environment as a climate ecotone for studying processes of river incision, deposition, and soil formation. This is the first study in central Texas focused on alluvial floodplain and terrace formation of the Brazos and Bosque rivers. Additionally, Buttermilk Creek …

The Evolution of the Profile Paradigm in the History of Pedology and Quaternary Geology: Concepts and Applications
… defined scope than that traditionally used in pedology. In the traditional sense the interval between the solum and bedrock is designated as the C, whether pedogenically modified or not. In the PWP, the C horizon is limited to the part of the traditional C that is pedogenically altered. That …

The Application of Pedology, Stable Carbon Isotope Analyses and Geographic Information Systems to Ancient Soil Resource Investigations at Piedras Negras, Guatemala
<p>The ancient inhabitants of the Maya Lowlands enjoyed a long and fruitful period of growth which climaxed at around AD 800. At that time, millions of people successfully subsisted in a challenging environment that today only supports a population a fraction of that size. These facts, and the …

Integrating basic remote sensing, terrain analysis and geostatistical methods to generate spatially explicate continuous soil attribute maps for Fraser Experimental Forest
… of Soil Formation, a system of quantitative pedology (1941), concisely summarized and illustrated many of the basic principles of pedology utilized to date (Jenny, 1941). This state factor model became the backbone for soil survey research and production because it proposed that a limited …

Geoarchaeology of the Danilo Bitinj and Pokrovnik Sites, Dalmatia, Croatia
… detailed study of the early farming landscape. Pedology and geomorphology combine in the reconstruction of Neolithic paleoenvironments and the investigation of conditions affecting the preservation of archaeological remains. This site-specific geoarchaeology provides a dataset critical to the …

A Methodology for Reservoir Site Selection for the Maintenance of Impounded Water Quality
… was established. Background information on pedology, geology, and geomorphology was reviewed. A base map of the study region was compiled from National Topographic System maps. Information from many hundreds of existing testholes and water wells was plotted on the base map. Water wells in …

A generic protocol for an integrated land information system in humid subtropical highlands: a case study in Yunnan Province, China
… meteorology, geology, geomorphology, biology, pedology and crop productivity, was integrated using a geomorphopedological approach and expressed as maps using GIS. The developed protocol is proposed as a generic system, applicable to agricultural land evaluation in subtropical highland …

Bryophyte and macrolichen diversity of the Purdiaea nutans forest in southern Ecuador and its relationship to soil, climate and vegetation structure
… abiotic factors, related to topography, geology, pedology, and macroclimate. Neither the terrestrial nor the epiphytic bryophyte and macrolichen species richness or composition were affected by the unusual tree species composition, but instead represent typical upper montane ridge communities of …

Living near permanent water in the upper Murray-Darling Basin Implications from the micromorphology of buried soils near artesian springs
… gullies (arroyos), soil micromorphology and pedology, and optically stimulated luminescence (OSL) dating provide a framework for the palaeo-human setting. It considers several questions, including: When did landscapes change and why? How did dry and humid conditions effect the circumstances …

Physical and geochemical characterisation of canal sediments in the Black Country, West Midlands.
… in a wide variety of disciplines, including pedology, chemistry, pollution science and medicine. Within the scientific community, emphasis has usually been placed on the toxic elements, such as cadmium, chromium, lead and arsenic, but rarely has there been consideration of interactions …

Weathering and soil properties on catenary sequences in forest and alpine ecosystems of the central Rocky Mountains
… from the integration of and consideration of pedology, geomorphology, and hydrology. The future of pedological research will involve the assimilation of multidisciplinary approaches and thinking. This dissertation elucidates on (1) the distribution of soil properties along soil catenas and …

Catchment Structure Regulates Hydrodynamic Drivers of Chemical Weathering in Shallow Forest Soils
Determining where, when, and how subsurface flow affects soil processes and the resulting arrangement of soil development along flow paths is challenging. While hydrologic regime and soil solution acidity are known to influence weathering rates and soil transformation processes, an integrated …

Rilevamento e rappresentazione cartografica della variabilità spaziale dei suoli a differenti scale d'indagine: i casi studio di Monastir e del Foglio 549 Muravera
The considerable spatial variability of soils makes the possibility of making teoric models of survey and representation difficult. Nowadays, traditional surveys and others using the application of new technologies are still the best way to mark soils in a specific area. One main difference is that …

Classificação supervisionada de solos por redes neurais artificiais na Serra do Cipó - MG
A classificação supervisionada de solos, especialmente nas últimas décadas, vem sendo realizada com o auxílio de modelos matemáticos e estatísticos, dentre os quais destaca-se o modelo de redes neurais, o qual tem apresentado exatidão superior quando comparado com métodos clássicos, como o de …
