the main objective of the present study was investigation on influences of different brackish water sources on freshwater prawn larval quality and developmental indices. for this study, along a larval period, four brackish water treatments with 12 ppt salinity including diluted marine water, brackish water from marine crystalline salt, brackish water with compounds of new formula and brackish w...
The quality of water resources is one the main subjects in ensuring public health. Therefore, monitoring resources, especially surface waters, leading operational management systems’ requirements.
Background and Purpose: Investigation of water quality is an important step for the suitable use of water resources in order to drinking and irrigation. Water quality affects agriculture programming. Hence the need of the study of water quality is strongly considered in the water resources management. Material and Methods: In this study Hydro-geochemical quality of ground water resou...
Background: Unsustainable development of agriculture and aquaculture has reduced the water quality of rivers. The most important aim of this study is assessing of water quality in the Ghezel Özan basin in Zanjan province. Method: 18 sites were selected based on standard criteria including land use, geology, biodiversity points, accessibility and standard distributions. Content of Dissolved Oxyg...
This study was conducted over seven villages near Darbandikhan district including (2) wells and (5) springs. It covers more than 60 km, to assess the suitability of ground water quality for drinking purpose using water quality index through investigating of different wells and springs; this technique is very useful tool for quick assessment for any water system. This was done by subjecting the ...
Introduction: Groundwater is the main source of water supply for agricultural purposes, especially in arid and semi-arid regions. the Water Quality Index (WQI) is used to provide early and quick results of the assessment of water quality status, IRWQI has been developed with the aim of using appropriate method with natural conditions and water resources issues in Iran. In this research, the tre...
Background and Objectives: Aydughmush dam was built on Aydughmush River at 19km in southwest of Mianeh City. The dam is multipurpose and its main aims are the spring floods control, supplying potable water for villages and providing irrigation water. Different pollutants which probably discharge to the river finally enter to the dam reservoir so this study focuses on evaluating the quality of t...
the selection of high yielding and stress tolerance plant genotypes with the highest water use efficiency and productivity is one of the most important tools for field water management in arid and semi-arid regions. this study was conducted to identify drought tolerant flax families with the highest irrigation water productivity (iwp) among a population of 119 f3 families derived from a cross b...
The aim of this study was to assess the drinking quality of Shahrekord aquifer based on a GWQI (groundwater quality index) within a GIS framework. To do this, samples from 97 wells were analyzed for pH, Electrical Conductance (EC), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Turbidity, Ca2+, Mg2+, Na+, K+, Cl-, HCO3- and SO42-, and total hardness was also calculated. These water...
