In this study, the seasonal variation on drainage water quality of Çarşamba Plain, Turkey has been evaluated from June 2012 to January 2013 and determined the suitability of water for irrigation purpose. Water samples collected from 21 drainage canals during July and January were analysed for 12...

The need for efficient and economical use of the world’s water requires the implimentation of modern methods to make decisions about water management. This inspired the principal philosophy of the management study of the Hellenic part of the Strymonas River catchment (6400 km 2). An important issue...

Slaughterhouse wastewaters are characterized by a high organic content, mainly composed of proteins and fats. Therefore, these wastewaters should be treated efficiently prior to discharge into receiving bodies to avoid severe environmental pollution. This work aimed to characterize slaughterhouse...

In this paper, ethylene glycol wastewater (EGW) treatment was studied by using one anaerobic polyvinyl alcohol (PVA) gel beads based biofilm reactor. Enhanced by PVA-gel beads based biofilm, organic loading rate (OLR) about 11 g COD l -1 d -1 was achieved at the end of this study. Black PVA-gel...

This study was conducted to investigate the effect of praestol, as a coagulant-aid, to improve coagulation-flocculation process in the removal of disperse red 60 from aqueous solutions. The effect of various parameters including coagulants dose (10-1000 mg l -1), praestol dose (0-1000 mg l -1)...

Biosorption is an emerging technique for water treatment utilizing abundantly available biomaterials.The potential feasibility of magnetic peanut hulls particle for removal of cationic dye (methylene blue) from aqueous solution was investigated. The effects of various experimental parameters were...

In this study, we investigated the separate and combined impacts of climate and land-use changes on hydrological response in the Central Highlands of Vietnam during the period 1981-2009. The Mann-Kendall and Pettit tests were applied to detect the trends in the hydro-meteorological data. The Soil...

Civilization has been experiencing frequent changes in the climate due to global warming. The developing nations are worst affected as they are largely dependent on the local precipitation and soil moisture for their livelihood generations. The changing climate with extended summer, change in the...

This study aims to measure citizens’ behavior intention (BI) in Environmental Impact Assessment (EIA) participation. An extended theory of planned behavior (TPB), which includes perceived government support and perceived environmental concern, is used as the predictor model. A total of 240...

This work has exploited a Genetic algorithm for oil spill automatic detection. This is implemented to sequences of RADARSAT-2 SAR ScanSAR narrow single beam data in the Gulf of Mexico. The study shows that the implementation of crossover is generated an accurate oil slick pattern. This is confirmed...

A method is proposed for the assessment of the interactive accumulation of heavy metals in soils. Sixty surface soil samples were collected from fifteen sites, at a depth of 0-30cm, evenly distributed, within the 30,700ha comprising the study area. It was found that at least some of these metals...

Dust pollution is a major problem in opencast mines. Many activities are associated with generation of dust that makes a cloud of pollutant at the work environment and the surrounding areas. Activities as drilling, blasting, transportation, surface miner etc. are the principle sources of generation...
