assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. however, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. therefore, in thiscase study, some water quality parameters including na, mg,...

This study was conducted for palynological investigation of recent deposits from east Isfahan in order to reconstruct past environmental conditions of this region. Segzi area is located in 30 km east Isfahan and Rangideh area is 65 km in south east Isfahan. In these areas it was seen, in depth of soil profile, dark layers containing organic matters. Soil samples were taken from five points and ...

one of the characters in iranian model of desertification potential assessment (imdpa) is soil. since soil is very important in the degradation of land, so some indices were determined for this character in order to evaluate desertification potential of arid, semi-arid and dry sub humid areas of iran. the indices included soil texture, deep gravel percentage, soil depth, and ec. to calibrate th...
