With a mean precipitation rate, much lower than that of the world, Iran is among the countries that face severe water challenges. The present study has dealt with the evaluation of hydrochemistry of Faryab spring water in Hormozgan Province, Iran. Four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, pH, and s...

The present paper sought to assess some physico-chemical parameters above permissible guidelines of irrigation water standard, the study was carried during establishment Ecotourism Park. field survey design used and it accompanied by laboratory tests analyze levels in both seasons (dry season wet seasons) for bodies as well groundwater. physical chemical analysed were Sodium Adsorption Ratio (S...

In this paper, we report the results of four ensemble approaches with the M5 model tree as the base regression model to anticipate Sodium Adsorption Ratio (SAR). The ensemble methods that combine the output of multiple regression models have been found to be more accurate than any of the individual models making up the ensemble. In this work, the additive boosting, bagging, rotation forest, and...

Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses o...

The objectives of this study were to investigate the degree of spatial variability and variance structure of salinization parameters using classical and geostatistical method in Songnen Plain of China, which is one of largest saline-sodic areas in the World, and to analyze the relationship between salinization parameters, including soil salinity content (SC), electrical conductivity (EC), sodiu...

Underground reservoir technology can mitigate water shortage and pollution problems in coal mining areas has a good application prospect. While still new technology, the theory method of underground reservoirs need to be improved. This research focused on hydrochemical characteristics mine their significance for site selection reservoirs. With Shendong area as case study, major ions, toxicologi...

an accurate design of drip irrigation requires water quality analysis that helps attain a better emission uniformity coefficient. this study examined aquifer qualitative parameters in the north of khuzestan province to assess the applicability of groundwater in trickle irrigation systems. for this purpose, interpolation technology was used to map chemical parameters collected from 104 deep well...

The main purpose of the current research is comparing the results of Artificial Neural Network (ANN) with Adaptive Neuro-Fuzzy Inference System (ANFIS) with regard to determination of the importance of soil properties affecting clay dispersibility. After taking samples from two depths of 0-40 and 40-80 cm, the spontaneous and mechanical dispersions of clay were recorded using both weighing and ...
