Interpretation of groundwater chemistry data using multivariate statistical techniques
Water Quality
Hydrogeologists in general and hydrogeochemists in particular are commonly asked to collect and interpret groundwater chemistry data for determining the groundwater quality at a particular site. More often, this involves graphical representation of data and a comparison with the drinking water...
Windrow Composting of Waste Sludge and Effects Composts On Plant Growth and Soil Characteristics
Solid Waste Management
Sludge is the ultimate by product of all traditional and conventional wastewater treatment processes. Conversion of the treatment sludge into new products is a significant disposal alternative for these wastes. In this study, branches, leaves and the organic and inorganic trash coming out from the...
Enrichment of sediments in urban rivers by heavy metals
Water Quality
The heavy metals contained in sediments may be responsible for constant degradation of rivers’ water quality, which circulate in an urban environment. Therefore, this study shows the pollution index and enrichment factor for each of these elements in river sediments. It was used the optical emission...

Water Resources Management
The meteorological, physical and hydrological conditions prevailing in a hilly area, namely the region around Malaxa (Western Crete), are analyzed and investigated in relation to water harvesting applications. The literature relating to water harvesting techniques and applications is reviewed and...
Performance, yield and characteristics of bioflocculants (UPMBF13) produced by Bacillus subtilis UPMB13 during submerged and solid-state fermentation
Solid Waste Management
This study compares the distinctive performance, yield and characteristics of bioflocculants (UPMBF13) derived from submerged (SmF) and solid-state fermentation (SSF) of Bacillus subtilis UPMB13. The bioflocculants were subjected to morphological characterization, functional groups determination...
Vulnerability of the Indus River Delta of the North Arabian Sea, Pakistan
Hydrology and water resources
Seawater intrusion has been a serious problem in the Indus River Estuary (IRE) for decades. The literature reviews, hydrological and meteorological observations were analyzed to examine and discuss the causes and consequences of seawater intrusion in the IRE. Both sea water intrusion and coastal...
Satellite based detection of Volcanic SO2 over Pakistan
Air Quality
The present study is carried out to explain the presence of large concentrations of SO 2 in atmosphere of Pakistan during June, 2011. Large volcanic eruptions are a major source of greenhouse and trace gases. The eruption of Mount Nabro in June, 2011 injected large amount of SO 2 into stratosphere...
An Experimental Study of Recoverable Products from Waste Tire Pyrolysis
Solid Waste Management
ºCIn this study, potential of useful products recovery was investigated from waste tires that completed the physical life by virtue of pyrolysis process. Disposal of waste tires, which is one of the global environmental problems, continues the presence thereof as a serious problem, especially in...
Degree of Wastewater Treatment versus Types of Reuses: Case Study, Saudi Arabia
Water Resources Management
The Council of Ministers issued a Royal decree number M/6 1421 H, corresponding to 2000 AD. The decree stated that, in Saudi Arabia, all wastewater should be treated at the tertiary level, without any discrimination (in terms of the type of reuse and discharge locations). The aim of this article is...
The majestic Hadrianic Aqueduct of the city of Athens
Water Resources Management
Athens in antiquity as well today, included all the settlements in the wider Attica region. That is why its official name was “the Athens” (plural). Since prehistoric times, the city of Athens and the wider region of Attica did not contain many natural water sources so aquatic reserves were never...
Experimental investigation of biogas production from cytrus waste: Co-digestion with cattle manure
Sustainable Energy
Biogas production through anaerobic co-digestion of a mixture of cattle manure and citrus waste using an experimental facility for testing the biochemical methane potential (BMP) was investigated. No buffer solution is added to the mixture in order to use the buffer capacity from cattle manure...
Water Solution Polishing of Nitrate Using Potassium permanganate Modified Zeolite: Parametric experiments, kinetics and equilibrium analysis
Water Quality
In the present study, adsorption potential of potassium permanganate (Hypermangan) modified zeolite was investigated for the removal of nitrate from synthetic wastewater. Effects of the most significant parameters (pH, adsorbent dose, nitrate concentration and contact time) were initially evaluated...
Cultivation of Medicinal and Aromatic Plants in Heavy Metal-Contaminated Soils
Pollution Control Technology
The growing number of polluted land areas makes the question of rehabilitation and safe/effective use of these areas increasingly imperative. For land polluted by heavy metals, the possibility of transferring the toxic pollutants to humans through the food chain further increases the importance of...

Water Quality
Rapid development in industrial sectors and population expansion has adverse impact on the Cooum river basin, especially Chennai region. The present study focuses on the assessment of seasonal variation in surface water quality of Cooum river basin. The samples were collected seasonally and are...
Changes in antioxidative systems and membrane stability index of canola in response to saline soil and fertilizer treatment application
Ecosystems and Natural Resources Management
The ability of fertilizer treatments (O (Optimum level), OP (Optimum level + twice amount of K +), OZ (Optimum level + twice amount of Zn 2+) and OZP (Optimum level + twice amount of K + + twice amount of Zn 2+)) to ameliorate salinity stress was studied in canola plants. In addition, fertilizer...
Time Series Models of Monthly Rainfall and Temperature to Detect Climate Change for Jorhat (Assam), India
Climate Change Impacts and Societal Adaptation in the Indian Subcontinent
In the present study, monthly rainfall, maximum temperature and minimum time series models were developed for Jorhat (Assam) situated in northeast India using monthly rainfall, maximum temperature and minimum temperature data from the year 1965 to 2000. A trend free time series of rainfall and...
Tourism Climate Comfort Index (TCCI) – An attempt to evaluate the climate comfort for tourism purposes: the example of Serbia
Global Environmental Change
This paper proposes one new attempt to formulate a mathematical approach to climate parameters in the context of their complex implications for tourist activities through the tourism climate comfort index (TCCI). This paper also aims to formulate an original and optimal mathematical correlation...
Modeling Dryness Severity Using Artificial Neural Network at the Okavango Delta, Botswana
Hydrology and water resources
Water balance studies in the Okavango Delta indicate that more than 90% of inflow into the Delta is lost through evaporation. This coupled with high climatic variability threatens the ecohydrology of the Delta. Trends indicate decreasing rainfall amounts and increasing temperature at the area of the...
