A High Cation Exchange Capacity (HCM) montmorillonite clay has been prepared by acetate treatment of Zenith clay. The HCM has been evaluated for metal-uptake from aqueous solutions. The present data show that the cation exchange sites can play a significant role in the adsorption of metals in...

The use of Geographical Information Systems (GIS) for Landfill Sitting is studied. The necessary spatial information required to determine the candidate sites for any type of terrestrial area (Community/Prefecture/Region/Country) is examined. This spatial information is then used for site selection...

Sewer systems may often operate as bioreactors causing considerable wastewater quality changes and in some cases reducing the pollution load conveyed to the treatment plant. Conceptually, transformation of organic matter takes place both in the bulk water (by suspended micro-organisms) and by the...

The transport of volatile organic contaminant (VOC) mixtures in the unsaturated zone is typically controlled by a combination of transport (i.e., advection, dispersion, and diffusion) phenomena, phase change (i.e., volatilization, dissolution) and reaction processes (i.e., sorption, biodegradation)...

The Plastiras dam was constructed in the late 1950s mainly for electric power production, but it has also partially covered irrigation needs and water supply of the plain of Thessaly. Later, the site has been designated as an environment conservation zone because of ecological and landscape values...

Agriculture is an economic activity that contributes significantly to the gross national product of a country, securing at the same time the viability of the rural sector and the social coherence. On the other hand, it can generate an environmental externality, especially concerning water resources...

The subject of this article is the estimation of quantitative (hydrological) and qualitative parameters in the catchment of Ronnea (1800 Km2, located in south western Sweden) through the application of the Soil and Water Assessment Tool (SWAT). SWAT is a river basin model that was developed for the...

The understanding of marine eutrophication in semi enclosed areas due to agricultural runoff, assumes a more integrated approach taking into account the agricultural watershed, seasonal patterns of soil nutrients, rates of erosion and vegetation types. In the present case study in the Gulf of Geras...

The assessment of the applicability and suitability of potential measures and instruments is crucial in the strategic planning of water resources management. This paper presents a methodology founded on scenario analysis for assessing potentially applicable water management options in a regional...

Estimation of annual water balance is critical for water management and developmental planning in the area of Anthemountas river basin. In the framework of LIFE04/ENV/GR/000099 project and in continuance to prior projects in the area, the average annual water balance was estimated using the annual...
