land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. the rate of thisphenomenon is high in developing countries such as iran. this research investigated desertification and mapping ofdesertification in abuzaydabad, near kashan, iran, with an emphasis on land criteria using an imdpa model.different studies have assessed land degradation or desertificat...

This article provides a background for scientists interested in a general overview of the geology and geomorphology of Turkmenistan. The basement of Turkmenistan is a complex amalgamation of arc-related terranes developed in the Asiatic and northern Paleotethys oceanic domains during Late Paleozoic to Triassic times. A major part of the country coincides with the Turan Platform, where a thick s...

Geodiversity is considered as the natural range of geological, geomorphological, and soil features, including their assemblages, relationships, properties, interpretations, and systems. A method developed for the quantitative assessment of geodiversity was applied to Paraná, a Brazilian state with an area of about 200,000 km(2). The method is based on the overlay of a grid over different maps a...

Interpretation of subsurface geology is greatly enhanced by 3-D seismic data, and this accounts for its ubiquity in today’s search for hydrocarbons. Seismic interpretation has two fundamental disciplines at its core: seismic geomorphology and seismic stratigraphy. Plan views allow the explorationist to apply principles of geomorphology, based on analogies with modern sedimentary systems, to int...

Topics covered: 1. Conceptual framework – agents of pattern formation. 2. Abiotic factors – geology, geomorphology, hydrology, soils. 3. Climatic factors – temperature, precipitation, solar radiation, meteorology. 4. Climate-landform effects on vegetation pattern, ecological flows, disturbance regimes and geomorphological processes. 5. Resource management implications – climate change scenarios...

desertification is specific phenomenon of arid, semi-arid, dry sub humid regions. this phenomenon has a high rate in developing countries such as iran. the main objective of this research was calibration of imdpa model in abuzeidabad (kashan) region with emphasis on land criteria. imdpa model, introduced by iranian researchers to assess desertification intensity in iran. before application, the...
