The attractions and capabilities of geomorphosites are among the unique assets each country, their identification, classification, planning have great importance for development tourism. purpose this research was to identify, quantitatively analyse, classify landforms treated as geosites landscapes Yazd Province, using Pralong method. present study is a descriptive analytical based on library s...

snow cover area is one of the most important criteria to calculate snow melt runoff. this can have an effect on the biology of the plant and the environment of a region. using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. most of the useful methods in calculating snow cover area are based on satellite i...

recently, some specimens of genus apodemus were found from shirkooh mountains of central plateau of iran. in order to certify morphologic and morphometric studies, a study has been carried out on the genome of these specimens using random amplified polymorphism dna (rapd) marker. nine random primers were used. the analysis of data determines the separation of avicenna's wood mice as a new speci...

background: radioactive substances are water chemical contaminants. in this study, the concentration of radon was measured in drinking water supplies of taft villages (part of dehshir-baft fault located in central part of iran) and also shirkooh area with granite rocks (containing uranium). materials and methods: this cross sectional research was conducted in fall 2013 and winter 2014 on the so...

Rainfall, soil moisture, increasing temperature and changes in vegetation cover are the most important parameters effecting drought. Therefore, analysis of vegetation fraction and soil spectral signature, especially in red and infra red bands, are essential in drought estimation using remote sensing. In this study, Modified Perpendicular Drought Index (MPDI), which uses Vegetation Fraction (VF)...
