Groundwater resources along with surface-water meet the needs of urban, industrial, and agricultural sectors, therefore, their quality should be examined. Water indices are useful tools for aquifer management. In this research, groundwater Miandoab Plain in province West Azerbaijan, northwest Iran, purposes was investigated. For purpose, concentrations ions Mg2+, Ca2+, Na+, HCO3−, SO42−, Cl− pH...

The present study was carried out using artificial neural network (ANN) model for predicting the sodium hazardness, i.e., adsorption ratio (SAR), percent (%Na) residual, Kelly’s (KR), and residual carbonate (RSC) in groundwater of Pratapgarh district Southern Rajasthan, India. This focuses on verifying suitability water irrigational purpose, wherein more decline coupled with quality problems co...

soil moisture retention curve is one of the soil hydraulic prosperities which its direct measurement is time consuming and expensive. therefore, indirect methods such as developing pedotransfer functions have been used to predict this characteristic from soil readily available or easily measurable data. in this study, multiple linear regression method was used to develop point pedotransfer func...

We report on the adsorption of sodium dodecyl sulfate (SDS) onto functionalized graphene sheets (FGSs) in an aqueous system, measured at broad SDS and FGS concentration ranges by conductometric surfactant titration. At dilute SDS concentrations (<12 μM in bulk solution), there is evidence of a counterion exchange between hydronium ions (from the dissociation of acidic chemical functionalities o...

Insufficient water is the greatest limitation to crop production and choice of crops grown in the Northern Great Plains. Supplemental irrigation can overcome this limitation. Uncertainties about the drainage capacity of flne-textured subsoils and the effect of irrigation on soil properties has impeded irrigation development. In this study we quantified salinity changes in soils with fine-textur...
