Chlorine was accepted as an effective disinfectant for drinking water in early 1900s. Because of chlorination, chlorine has dramatically reduced the incidence of waterborne diseases. An unwanted side effect is the formation of harmful by-products upon chlorination. The most significant group of...

Activated carbon (AC) is currently being used to treat polychlorinated biphenyl (PCB) contaminated field sediment. In the presence of sediment, the sorption capacity of AC for PCBs can be reduced. In this study, sorption attenuation of AC is investigated using previously published data from 5...

The El Nino-Southern Oscillation is the dominant pattern of short-term climate variation, and is therefore of great importance in climate studies. Some recent studies showed the teleconnection between stream flow and the El-Nino Southern Oscillation (ENSO) of the equatorial Pacific Ocean. This paper...

The Olympic Rowing and Canoeing Center constructed at Schinias, accommodated the rowing and canoe – kayak sprint competition of the 2004 summer Olympic Games.

The Cost-Effectiveness Analysis (CEA) is the method most commonly used for the assessment of the costs and effectiveness of alternative policy options on the environment. The objective of this paper is to describe the priority of the policy area “coastal water pollution control from land uses, in...

In order to evaluate how current speed, salinity and water temperature stratification behaves under the influence of a freshwater source in a tidal domain, a 25 hour survey campaign was performed in the upper sector of the Vouga River estuary, the major source of freshwater of Ria de Aveiro, a...
