We estimate the nutrient budget in a temporary Mediterranean river basin. We use field monitoring and modelling tools to estimate nutrient sources and transfer in both high and low flow conditions. Inverse modelling by the help of PHREEQC model validated the hypothesis of a losing stream during the dry period. Soil and Water Assessment Tool model captured the water quality of the basin. The ‘total daily maximum load’ approach is used to estimate the nutrient flux status by flow class, indicating that almost 60 % of the river network fails to meet nitrogen criteria and 50 % phosphate criteria. We recommend that existing well-documented remediation measures such as reforestation of the riparian area or composting of food process biosolids should be implemented to achieve load reduction in close conjunction with social needs. 相似文献

Environmental policies aimed at the conservation of protected areas are significantly influenced by social factors revealing the importance of investigating local knowledge and perceptions during their planning and implementation. The present article aims to explore perceptions and awareness of citizens in three protected areas of Greece: The National Park of Eastern Macedonia and Thrace, the Wetland of Kalloni, and Lake Tavropou. The survey explores perceptions of individuals on environmental issues and alternative management scenarios referring to management actors, funding sources, and management schemes for the conservation of biodiversity. Differences between the three research areas are also explored. According to the results of the study, citizens are in general supportive of protected areas and present relatively high levels of knowledge of environmental issues. However, environmental awareness is not accompanied by active participation for the resolution of environmental problems. By exploring differences between the three research areas, it is revealed that the provision of information significantly influences individuals’ perceptions on relevant issues. Also, a significant finding of the study is that citizens are supportive of some forms of participatory management. It is essential, to encourage public participation and deliberation in order to promote their sustainable management. 相似文献

The impact of weather on air pollution was examined and evaluated for the city of Athens, Greece. We used an objectively defined synoptic classification scheme consisting of six summer and eight winter circulation types. This scheme was established using a combination of both factor and cluster analysis during 1954-1999. Surface and isobaric levels of 850 hPa data were used. Factor analysis combined with cluster analysis was used to derive circulation types based on surface meteorological data for the period 1954-1999 in Athens and on surface pressure grid data. The city was divided into three sectors according to the financial and social activities of the residents. To examine the spatial characteristics of pollutant concentrations over Athens for each synoptic type, the synoptic circulation types were then correlated with both gaseous and particulate pollutant concentrations measured in each sector between 1983 and 1999. Finally, extreme and severe episodic events were studied in terms of their meteorological and synoptic characteristics. 相似文献
