abstract geomorphology and soil genesis and its development are closely related. besides, soil-landscape studies provide a better understanding of soil forming processes. the objectives of the present research include soil genesis studies, micromorphology and clay mineralogy of soils related to geomorphic surfaces in jiroft area. soil temperature and moisture regimes of the area are hyperthermi...

The Antarctic Dry Valleys (ADV) are generally classified as a hyper-arid, cold-polar desert. The region has long been considered an important terrestrial analog for Mars because of its generally cold and dry climate and because it contains a suite of landforms at macro-, meso-, and microscales that closely resemble those occurring on the martian surface. The extreme hyperaridity of both Mars an...

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 ...

federal lands to facilitate resource extraction, recreation, and transportation (Havlick 2002) – enough to drive to the moon and back. While these roads provide important services, their construction and presence can also influence the hydrology, geomorphology, and ecosystem processes. They can substantially alter hillslope hydrology by reducing soil infiltration, concentrating water through ro...

The paper reviews a set of soil surveys carried out in Iran using a geopedologic approach for different surveying aims in different scales. Most of these studies have implemented a similar survey method including the following steps: delineation of landforms from air photos using geomorphic and soil-landscape relationships, field check of the delineations, sample areas inventory with soils clas...

Well-constrained case studies of transient landscape response to external forcing are needed to improve our understanding of erosion processes in tectonically active mountain belts. The Peninsular Ranges portion of the San Jacinto fault zone (SJFZ) is an excellent location for such a study because it displays pronounced geomorphic disequilibrium resulting from initiation of a major strike-slip ...

This paper deals with the study of Holocene geomorphic evolution of rivers around Songshan Mountain in relation to human frequentation in Prehistoric periods. The investigations were performed by means of an integration of GIS data processing; field surveys and particle size analysis. In 8000–3000 aBP; in the Songshan Mountain Region, large-scale river sedimentation occurred. This increased the...

Digital elevation models (DEMs) are increasingly used for visual and mathematical analysis of topography, landscapes and landforms, as well as modeling of surface processes. A DEM of Cerro Sillajhuay, a volcano in the Andes of Chile/Bolivia, was developed from ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) satellite data. The original 30-m DEM was generated by using tie ...

This paper deals with a landscape evolution model to compute cockpit karsts landforms. The CHILD model is used to model geomorphic processes at regional scale. After examining briefly CHILD’s principles and equations of limestone dissolution processes, the denudation model is detailed. The relation between subcutaneous dissolution and denudation of the topography is introduced by means of an em...
