abstract geopedology is a systematic approach of geomorphic analysis for soil mapping which focuses the field operation mainly on sample area. the purpose of this study is to determine the credibility of generalization of the results of geopedological approach for similar landforms in the borujen region, using diversity and similarity indices in a soil taxonomic hierarchical structure. after a ...

global warming is claimed to be the cause of climate change, which is often held responsible for water shortage.  let geopedology represents the complex process of soil formation, out of which much can be learnt about paleoecology; soil formation being a dynamic interaction between the atmosphere, biosphere, lithosphere, and the hydrosphere. in a multidisciplinary sustainability-oriented study ...

The idea that soil or the pedosphere is connected to other terrestrial spheres dates back at least 1880. Some 26 years later, interdependency of was established, but a fully integrative approach addressing interdependence biosphere, pedosphere, atmosphere, hydrosphere, geosphere, and toposphere did not emerge until advent Earth Systems Science during 1980s. A significant development within re-e...

soil, a 3-dimensional component of the landscape, or simply a natural body in a soilscape with a given geopedological setting, was modeled by jenny as s = f (climate, organism, relief, parent material, time). to map such a complex body, the concept ‗pedon’ –the smallest volume that can be recognized as a soil had to be defined. classically, soil is known to function as provider, controller, reg...

In extreme value statistics, the extreme value index is a well-known parameter to measure the tail heaviness of a distribution. Pareto-type distributions, with strictly positive extreme value index (or tail index) are considered. The most prominent extreme value methods are constructed on efficient maximum likelihood estimators based on specific parametric models which are fitted to excesses ov...

today, extensive improvements in fields of soil mapping have increased the purity and accuracy ofsoil maps. usual mapping methods moreover depend on skills and experience of surveyor inidentifying and delineating the boundaries, also need the high cost and time consuming that face thesoil mapping with restrictions. in this study, aerial photographs with 1/40000 scale were used in orderto prepar...
