in recent years, the water quality of karun river, iran, has been affected by different pollutant loads such as agricultural drainages, municipal and industrial wastewaters.water quality index (wqi) and gis as an efficient tool can be used to provide necessary support for decisions of the management actions in this river and also capability of time series models can be beneficial for forecastin...

Kosovo has limited natural water resources which should be well managed. This is recently realised through quantitative and qualitative monitoring of both surface and groundwater and by characterizing their quality according to their destination. In this paper, the Water Quality Index (WQI) developed by the Canadian Council of Environment Ministers (CCME WQI) was applied to evaluate the groundw...

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...

Water quality indices (WQIs) are efficient and powerful tools for evaluating, organising and communicating information on the overall quality of surface water bodies. The use of these indices may be very helpful in evaluating the water quality of aquatic systems in relation to the EU Water Framework Directive (WFD). In this study, two well-known water quality indices have been selected for eval...

Egypt is one of the most vulnerable countries to the potential impacts and risks of climate change. More than 95 % of the water budget of Egypt is received from the River Nile, which is very sensitive to temperature and precipitation changes. Aswan High Dam (AHD) reservoir, one of the largest man-made lakes in the world, is almost the sole source of freshwater to the country; hence, Egypt reali...

Excessive population growth and high water demands have significantly increased extractions from deep semi-deep wells in the arid regions of Iran. This has negatively affected quality different areas. The Water Quality Index (WQI) is a suitable tool to assess such impacts. study used WQI fuzzy hierarchical analysis process index (FAHP-WQI) investigate status 96 agricultural Yazd-Ardakan Plain, ...

Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Th...

Abstract The objective of this research was to arrive at a better assessment the quality surface water in Constantine region. focus on comparison three classical indices WQINSF (National Sanitation Foundation Water Quality Index), WQICCME (Canadian Council Ministers Environment Index) and WQIAP (weighted arithmetical development new index prediction by ANN (artificial neural network) WQI indice...
