Our main objective in the present study was to assess the spatial variation of chemical and physical water properties. Prior to the design of groundwater quality monitoring networks, it is essential to investigate the spatial structure of the groundwater quality variables. A case study is presented which used ground water quality observations from groundwater domestic wells in the Dameghan, Ira...

The study has been carried out to assess surface water quality of Old Brahmaputra River from September 2015 to March 2016. DO, BOD5, COD, pH, EC, Chloride, Alkalinity, and Hardness concentrations in water samples have been found to range within 0.66-2.9 mg/L, 21-138 mg/L, 45-250 mg/L, 7.1-7.8, 185-1080 uS/cm, 10-98 mg/L, 85-197 mg/L, and 84-148 mg/L, respectively. Multivariate statistical analy...

abstract- as the world's population has grown and become more urban and affluent, waste production has raised drastically. wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. to address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments o...

Targeting specific locations within agricultural watersheds for installing vegetative buffers has been advocated as a way to enhance the impact of buffers and buffer programs on stream water quality. Existing models for targeting buffers of Hortonian, or infiltration-excess, runoff are not well developed. The objective was to improve on an existing soil survey–based approach that would provide ...

Background & Aims of the Study: Water resources are useful or potentially useful. Uses of water are included agricultural, industrial, household, recreational and environmental activities. The majority of human uses require fresh water. Rivers are parts of this fresh water that play a very important role in the water cycle, acting as drainage channels for surface water. Hence, ...

the evaluation of the edge effects of forest roads on ecosystem is very useful to understand changes from forest road. with this regard, in this research the effect of main forest road construction on regeneration and biodiversity of established trees in edge of forest road was investigated at 35 m distance into forest area. an existing 10 years old road segment, with same physiographic propert...
