Background and Objective: Water quality assessment is an important step for optimal and proper use of water resources for drinking and selection of suitable and consistent water quality patterns. Therefore, the necessity of studying water quality characteristics in water resource management programs has been highly considered. Materials and Methods: In this study, the hydrogeochemical quality ...

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...

    Background & Aims : Water Quality Indices are one of the methods can be used in water quality management as a useful tool in decision making, so this study carried out on evaluating the quality of the Aydughmush river by National Sanitation Foundation Water quality (NSFWQI) and River Pollution Indices (Liou).   Materials & Methods : In this cross sectional study standard field parameters in...

Backgrounds and Objectives: The Atrak River is an important water supply resource in the Razavi Khorasan, Northern Khorasan and Golestan provinces. This river is the line border of Iran and Turkistan countries. Unfortunately, lack of water quality and quantity data due to nonexistence of a proper surface water quality monitoring station network is one of the main problems for water quality eval...

  Background and Objectives In recent years, excessive use of groundwater resources and the discharge of urban and industrial wastewater in the environment has contaminated and reduced the quality of groundwater resources. The aim of this study was to determine the quality of drinking water resources in Rafsanjan city using water quality index (WQI) in 2018. Materials and Methods: This descri...

In this study, the quality of groundwater aquifer of Gavkhooni basin was investigated in agriculture. For this purpose, water quality data related to 96 wells prepared by Isfahan Regional Water Authority during the statistical period 2015-2016 were used. In this study, sodium parameters, electrical conductivity, chloride, hydrogen bicarbonate and sodium absorption ratio (SAR) were used. Then, g...

This study was conducted with the aim of providing a remotely sensed water quality index in Assaluyeh port using remote sensing technology. so, according to the region conditions, studying of scientific resources and access to satellite data, the parameters of heavy­metals, dissolved ions, SST, chlorophyll-a and pH were selected. Then, by reviewing sources, the product MYD091km, MYD021km, MOD02...
