soil texture is an important soil physical property that governs most physical, chemical, biological, and hydrological processes in soils. detailed information on soil texture variability is crucial for proper crop and land management and environmental studies. therefore, at present research, 103 soil profiles were dogged and then sampled in order to prepare digital map of soil texture in bijar...

We introduce a novel method for classification and mapping of landforms based on the idea that the Earth’s surface can be described by the two complementary measures: relief-independent, local spatial pattern and the magnitude of the relief itself. The first of these two measures is sufficient to classify and map the landforms. At the core of the method is the concept of geomorphon (geomorpholo...

abstract many researchers have recently considered the use of data obtained from remote sensing (r.s) to reveal changes. in the present study, we have attempted to reveal the morphodynamic changes in taleghan river basin through image satellite and by analyzing the principal component analysis (pca) and fuzzy logic. the final map indicates the intensity of changes through, 15-years interval obs...

There are different models for mapping and evaluation of desertification condition, such as global FAO_UNEP model. There are also several models for evaluation of desertification in Iran. In this study, tow fol/owing methods was used: 1-ICD method, (Iranian Classification of Desertification). 2- MICD method, (Modified Iranian Classification of Desertification). In this research, at first, these...

kolah ghazi national park is one of the most important habitats for wild goat in iran with a population of around 2000 heads. in order to model the habitat for this species, a presence only layer was used as input to enfa method in biomapper software. ecogeographic factors were also used as independent variables including plant community, distribution of predators, geomorphologic features, main...

Floods are one of the most important natural hazards in world and Turkey, depending on their severity formation conditions, they can cause disasters by creating diverse negative impacts sources from effects or human intervention. In this study, flood susceptibility map was prepared conducting analysis Çerçi River Fethiye District Mugla Province, Turkey. While determining River, geologic, geomor...
