in this study, species richness, evenness and vegetation biodiversity were investigated in stabilized and non-stabilized cut edge areas of chachkam district forest roads in sari forest of iran. 18 micro plots 1×1m (36 micro plots) were sampled to carry out this research on two cut edge areas. number of trees, shrubs and herbaceous were recorded in each micro-plot. significant difference was inv...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

Background & Aims of the Study: The use of qualitative indicators is one of the ways of water quality of river water. The purpose of this study is Khorramrood River of Khorramabad of water quality using water quality index (NSFWQI) and GIS that is a Geographic Information System . Materials & Methods: In this cross-sectional study, qualitative parameters needed to calculate NSFW...

evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

in this research, the groundwater quality of abhar plain was studied for drinking, domestic and irrigation uses. to assess the evaluation of hydrochemistry and quality, 26 groundwater samples were collected and analyzed for the physicochemical factors such as ph, electric conductivity (ec), total dissolved solids (tds), total hardness (th), na+, k+, ca2+,mg2+, cl-, so42-, hco3-, co32- during oc...

Abstract The Water Quality Index (WQI) is a single, deferential metric for describing the state of water quality as whole, which aids in selection effective remediation strategies. Fifteen surface samples were taken from Euphrates AlHaydria neighborhood AL-Najaf (Iraq). Various physicochemical parameters, including pH, total dissolved solids (TDS), calcium, chloride, sulfate, and electrical con...

groundwater is the most widely distributed resource of the earth and groundwater quality evolves rapidly as it passes through the subsurface pathways within the unsaturated zone. increasing urbanization and anthropogenic activities have added to the problem of deficient amount of good quality groundwater. the study area is an industrial hub for textile sector. textile production, particularly d...
