Considering the complexity of hydrological processes, it seems that multivariate methods may enhance the accuracy of time series models and the results obtained from them by taking more influential factors into account. Indeed, the results of multivariate models can improve the results of description, modeling, and prediction of different parameters by involving other influential factors. In th...

The objective of this study is to determine various water characteristics the Bhima River and its suitability for drinking, followed by a quality index evaluation. For continuous monitoring, samples were taken at eight locations between October 2020 September 2021. physicochemical parameters, such as pH, electrical conductivity (EC), total dissolved solids (TDS), oxygen (DO), alkalinity (TA), h...

We assessed the physico-chemical status of twelve surface water samples from the Birjand flood plain (east of Iran) during fall 2010. The sampling points were selected on the basis of their importance. The physico-chemical parameters such as pH, temperature (T), electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), calcium (Ca2+), magnesium (Mg2+ ), sodium (Na+), pota...

This study was conducted to assess the effect of wastewater quality Paharang drain Faisalabad on ground water adjacent areas. Ground samples and were collected analyzed by using standard methods. Parameters compared with Pakistan National Environmental Quality Standards (NEQS). Results indicated that physico-chemical parameters including pH, total dissolved solids (TDS), chloride, fluoride hard...

the effects of industrial textile water(effluent water,ew) on soil, water and plant was investigated in this research. for conducting this research major important textile factory were selected and sampling was done in 2 stages and in 2 years. in each district and the control field (soil not irrigation with effluent water) the soils from 0-30 cm depth and plants were sampled in three replicates...

water is a unique natural resource among all sources available on earth. it plays an important role in economic development and the general well-being of the country. this study aimed at using the application of water quality index in evaluating the ground water quality innorth-east area of jaipur in pre and post monsoon for public usage. total eleven physico–chemical characteristics; total dis...

groundwater aquifers are an important source of water supply for agriculture, industry and drinking. the present study investigates the changes in the quality of groundwater using geostatistical methods in the ravar plain during a 10-year period. in this study, after selecting the appropriate spatial interpolation method to draw water quality parameters such as tds, sar and ec, zoning maps of r...
