background and purpose: today, by increasing different pollutants, the continuous monitoring of surface waters is essential. dorudzan dam is one of the main sources of surface water in fars province, iran; hence, the current study investigated the quality  of dorudzan reservoir for drinking and irrigation consumptions. materials and methods: in this study, various physicochemical parameters [ph...

Comprehensive assessment of water quality is an important technological measure for water environmental management and protection. Previous assessment methods tend to ignore the influences of sediment pollutant release and dynamic change of the water boundary. In view of this, this paper explores a new method for comprehensive water quality assessment. Laboratory simulation experiments are cond...

Rivers can be contaminated with different pollutants such as trout farms. Evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. In current work, the effect of constructed trout farms near the Deinachal River on some physicochemical properties namely chemical oxygen demand (COD), biological oxygen demand (BOD5), dissolved oxygen ...

Background: Survey of pollution and evaluation of water quality in rivers with Oregon Water Quality Index (OWQI) and GIS are effective tools for management of the impact of environmental water resources. The information in calculating the WQI of Moradbeik river allowed us to take our tests results and make a scientific conclusion about the quality of water. GIS can be a powerful tool for develo...

Groundwater is one of the most crucial freshwater resources in many parts world. However, growth population and different economic activities have negatively impacted groundwater quality. This study aims to assess quality An-Giang province, Vietnam, from 2017–2020 investigate its suitability for drinking via a new integrated-weight water index (IWQI). The samples were collected at thirteen well...
