DEVELOPMENT OF CONTINUOUS, LINEAR MODELS FOR MARINE BENTHIC MACROPHYTES DESCRIPTION

(Corresponding) TZOUVARAS N.
Topic: 
Marine environment and coastal management
The European Water Framework Directive has fostered indicator development, pertinent to biological quality elements, for ecological status assessment of coastal waters. For seaweed communities, the CFR index considers composition, abundance and physiological status, through four constituents (...Read more

Linear Bivariate Expressions for Marine Benthic Macrophytes Ecological Status Description

(Corresponding) Tzouvaras N.
Topic: 
Marine environment and coastal management
Regarding ecological status assessment with marine benthic macrophytic indicators as per European Water Framework Directive (WFD), linear models are being reviewed (either starting from discontinuous forms or modifying quadratic and algebraic forms). Through use of simple concepts, model...Read more

Challenges in biological treatment plants: the approach of zero sludge waste

THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic: 
Wastewater treatment
The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete...Read more

Natural presence of hexavalent chromium in spring waters of South-West Mountain Vermion, Greece

STAMOS A., SAMIOTIS G., PEKRIDIS G., TSIOPTSIAS C., (Corresponding) AMANATIDOU E.
Topic: 
Efficient water resources management in cr(vi) impacted water bodies
Hexavalent chromium in water occurs as oxoanions that are toxic for plants and animals. Furthermore, they are soluble and extremely mobile under environmental conditions. Chromium in its other common oxidative state (Cr+3) is less toxic and in general immobile. Chromium is found in nature mainly in...Read more

Greenhouse Gas Emissions from Natural and Artificial Lakes in Western Macedonia, Greece

TSIOPTSIAS C., SAMIOTIS G., KAKLIDIS N., PEKRIDIS G., (Corresponding) AMANATIDOU E.
Topic: 
Lakes, rivers, estuaries and ecosystem health
Formation of artificial lakes is a common practice for hydroelectric power generation. Hydroelectricity is considered to be a green and renewable energy source in terms of factory operation. However, hydroelectricity generation may have environmental impact arisen from greenhouse gas (GHG)...Read more

Mass and energy balances of sewage sludge pyrolysis in a lab rotary kiln

(Corresponding) Mendoza L., Gómez A., Rincón S.
Topic: 
Energy technologies and sustainability
The aim of this work is to study the influence of the main parameters of sewage pyrolysis in a rotary kiln on the product distriburion and energy balances. An indirectly heated rotary kiln at a laboratory scale was used (4 kg/h). An increase in the final temperature causes the reduction of the...Read more

Effect of anthropogenic sources on total particles and Cloud Condensation Nuclei levels in the Eastern Mediterranean

(Corresponding) Bougiatioti A., Zarmpas P., Kalkavouras P., Mihalopoulos N.
Topic: 
Urban environment and health
The absorption and scattering of radiation by atmospheric aerosol particles, especially those originating from anthropogenic activities, is a key component of anthropogenic climate change. Aerosol particles also act as cloud condensation nuclei (CCN) “indirectly” forcing climate through the...Read more

Greenhouse gases in the urban environment of Athens, trends and sources

(Corresponding) Bougiatioti A., Dimitriou K., Ramonet M., Pierros F., Michalopoulos P., Liakakou E., Solomos S., Quehe P., Delmotte M., Gerasopoulos E., Kanadikou M., Mihalopoulos N.
Topic: 
Climpact: national network for climate change and its impacts
Yearlong greenhouse gases (CO2 and CH4) concentration measurements were performed for the first time in the city of Athens, from 21/12/2018 to 31/12/2019, and analyzed in relation to atmospheric levels, wind direction at a local, regional and long-range transport scale. Clear diurnal and seasonal...Read more

The role of hydro-technical works in diminishing flooded areas. Case study: the June 1985 flood on the Miletin River

(Corresponding) Hutanu E., Urzica A., Paveluc L., Stoleriu C., Grozavu A.
Topic: 
Hydrology and water resources
Hydro-technical constructions are very important in diminishing flooded areas and associated damage in the event of a flood. The case study for the Miletin River in the Moldavian Plateau (Eastern Romania) focusses on the historical floods of June 1985. The floods recorded at the Miletin River...Read more

Dam break analysis using Hec-Ras techniques. Case study: Cal Alb dam (NE Romania)

Urzica A., (Corresponding) Hutanu E., Muhu-Pintilie A., Stoleriu C.
Topic: 
Hydrology and water resources
Along with the understanding of the importance of a water resource in the vicinity of a human settlement, human societies have begun to build weirs, dams or hydraulic structures to use more efficiently the natural resource. One of the most important works that can be done in the course of a river...Read more
