In this paper an Environmental Impact Assessment Multicriteria Decision Analysis System for irrigation projects (EIAMDAS) used as a comprehensive tool that enables comparison between irrigation project alternatives is presented. The comparison is based upon all relevant aspects of the surrounding...

In the Mediterranean region, fire is a natural factor, which contributes in the shaping of landscape and the preservation of a high degree of biodiversity. However, often repeated burning has negative impacts on the forested landscapes. When the processes of natural or artificial regeneration are...

In this work the covariability of sea surface and lower troposphere temperatures (SST-AT) is investigated for winter (DJFM) and summer (JJAS), over the whole northern hemisphere, by utilizing monthly anomalies in grid boxes for a 22-year period. Air temperature variations in the lower troposphere...

Odour emissions are a major environmental issue in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time...

Artificial neural networks (ANNs) are being used increasingly to predict water variables. This study offers an alternative approach to quantify the relationship between time of chlorination in potable water (due to convectional treatment procedure) and chlorination by-products concentration...

Environmental, economic and strategic reasons are behind the rapid impulse in the deployment of renewable energy sources that is taking place around the world. In addition to overcoming economic and commercial barriers, meeting the ambitious objectives set by most countries in this field will...

A set of anaerobic-anoxic-aerobic (A2/O) bio-reactor system was used to treat domestic sewage mixed with landfill leachate and fecal sewage in Datansha Sewage Treatment Plant in Guangzhou China. The experiment investigated the optimal mixing proportion of treating landfill leachate, fecal sewage...

The waste to renewable energy source has become a priority in the wastes treatment field. The research goal is not only the wastes destruction but also a better thermal energy recovery from the processes. The municipal solid waste presents a high heterogeneity degree from the dimensional point of...

The paper describes the development of a fast and easy-to-use qualitative tool for preliminary assessments of urban air quality related to road traffic. The tool is particularly aimed at the ability and budget of local government. It uses a novel interaction matrix-type methodology combined with...

Probability density functions (pdf) have been used in the analysis of the distribution of pollutant data, for examining the frequency of high concentration events. There have been very few studies on the concentration distribution of PM in urban areas. The distribution of PM concentrations has an...

Several epidemiological studies have shown an association between particulate air pollution and health effects. Suspended particulates and more specifically the inhalable PM10 fraction appear to cause respiratory health effects and heart diseases. Furthermore, particulate pollution is of paramount...

The objective of this study was set on three goals: (i) Chemical and radiological characterization and leaching properties of the mixture of fly and bottom ash, (ii) Chemical, radiological and mineralogical characterization of the Kastela Bay sediments, and (iii) Estimation of the influence of...

The process of nitrification in wastewater treatment is widely accepted as a two-step process. In the first step the ammonia is oxidized to nitrite, a process considered to be carried out mainly by the Nitrosomonas sp., while in the second step the Nitrobacter sp. oxidizes the nitrite to nitrate...

Slurry seal is applied for low-cost paving and surface maintenance. The principal materials used to create slurry seal are aggregates, asphalt emulsion, water and fillers like Portland cement (mainly), lime and other materials. This paper presents the use of alternative fillers instead of expensive...
