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 parame...
the effective factors on water quality of seimareh and kashkan rivers in ilam and lorestan provinces
the quality of surface water within a region is mainly influenced by natural processes such as precipitation, soil erosion and weathering, geology, vegetation and anthropogenic activities. the most important factor is geological formation in watershed and water flow path. in this study, the spatial variations of physical and chemical parameters of surface water including ec, sar, cl and tds and...
Given the complexity of water quality data sets, resources pose a significant problem for global public order in terms protection and management. In this study, surface drinking irrigation purposes was evaluated by calculating Water Quality Index (WQI) Irrigation (IWQI) based on nine hydrochemical parameters. The discriminant analysis (DA) method used to identify variables that are most respons...
a case study was carried out to see the impacts of shrimp culture on the surface (pond) and ground water (tube-well) quality in three coastal sub-districts of bagherhat sadar, rampal and morrelganj of bangladesh. the people of rampal (100%), morrelgonj (87.5%) and bagherhat (75.5%) expressed that salinity of both surface and ground water increased after shrimp culture, and water becomes more tu...
Surface and groundwater resources such as Arnaveh karstic spring and Shirin Dareh reservoir are the main sources of drinking water and agricultural activity in the North Khorasan province, northeast of Iran. The main agents of this study are to evaluate the origin, hydrochemical and isotope characteristics of water resources and also suitability of the Shirin dareh reservoir water for drinking ...
Background & objectives: Irrigation water quality is a critical aspect of agricultural production especially in terms of human health and the environmental aspects. The aim of this study was to estimate the level of surface runoff and groundwater pollution used in the production of agricultural products in the south of Tehran. Methods: Sampling points included 14 points of surface water collec...
