Background and purpose: Using Water Quality Indices are necessary for monitoring the quality of water in various applications, including agriculture. This study aimed to assess the quality of Takab Sarugh river right branch by WILCOX index. Materials and methods: In this cross sectional study some quality parameters including water temperature, sodium, calcium, magnesium, total hardness, pH, e...
Continuous decline of groundwater quality for agricultural purposes has become a major concern in extensive arid and semi-arid regions. Therefore, mapping the quality of groundwater on a broad scale is an essential step in land management. This study aimed to map spatial distribution of two important groundwater quality indices including EC and SAR in Isfahan province, Iran, using geostatistica...
I develop an implicit finite-difference migration algorithm for tilted transversely isotropic (TTI) media. I approximate the dispersion relation of TTI media with a rational function series, whose coefficients are estimated by least-squares optimization. The dispersion relation of TTI media is not a symmetric function, so an odd rational function series is required in addition to the even one. ...
Introduction The increase in population and need for food has resulted in the development of agricultural lands and pressure on aquifers, which has led to a sharp decline in the quantity and quality of groundwater resources. In many countries, especially in arid and semi-arid regions, in which the average annual precipitation is not adequate to support water requirements, groundwater is common...

groundwater is the sole source of accessible resource for agriculture in zeviercherry- kherran plains and water quality often falls in brackish group. in order to determine the source of salinity and hydrochemical processess affecting groundwater environment of the area, 61 groundwater samples were taken for hydrochemical analysis and composite diagrams (two variant diagrams of total concentrat...
