A DPSIR approach to selected Cr(VI) impacted groundwater bodies within Attica and Eastern Sterea Ellada River Basin Districts
(Corresponding) Pyrgaki K., Argyraki A., Kelepertzis E., Botsou F., Megremi I., Karavoltsos S., Mpouras A., Dassenakis M., Hatzaki M., Dermatas D.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
The holistic approach of the Driver-Pressure-State-Impact-Response (DPSIR) analytical framework in combination with Geographical Information Systems was applied to selected Cr(VI) impacted groundwater bodies. For the characterization of “state”, 157 samples including field blanks were collected...Read more
Harmonization of sampling and chemical analysis for the study of Cr(VI) water contamination in aquifers of eastern Mediterranean and Oman: the CrITERIA project experience
(Corresponding) Argyraki A., Kelepertzis E., Pyrgaki K., Botsou F., Megremi I., Dermatas D.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
The CrITERIA project aims to deliver a harmonized data base, to assist water resource management organizations and water users on decision making when coping with water scarcity, climate extreme events and contaminated water. Contamination by Cr(VI) is used as an example of a specific water...Read more

Benchmarking indicators to assess the level of circular economy strategy in Local Level
Loizia P., Inglezakis V., Navarro Pedreno J., Lasaridi K., (Corresponding) Zorpas A.
Topic:
Circular economy and industrial symbiosis
Sustainable waste management is an important global environmental agenda in the twenty- first century. The quantity of global waste increases as the population and the level of resource consumption rise over time. The increased generation of waste is also producing bigger environmental deprivation...Read more
Thermo-physical properties of agricultural residues for syn gas production using thermo-gravimetric analysis
(Corresponding) kumar p.
Topic:
Energy technologies and sustainability
The thermal degradation behaviour and the activation energy can be integrated utilized to understand the behaviour and constituent of biomass degradation rate prior to gasification. Thermophysical properties of agricultural residues in order to facilitate its further processing and utilization for...Read more
Multivariate Statistical Analyses of Groundwater Hydrochemical Data of Tirnavos Sub-basin (Central Greece)
(Corresponding) Vrouhakis I., Pisinaras V., Panagopoulos A., Stamatis G.
Topic:
Enviornmental data analysis and modelling
Abstract. Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were applied in the groundwater hydrochemical parameters dataset of the Tirnavos alluvial sub basin-central Greece. PCA results suggest occurrence of four principal components both for dry and wet periods. Results...Read more

Meteorological Data Science: exploiting causality discovery in time-series for knowledge discovery and improved forecasting
Gkikas A., (Corresponding) Maragoudakis M.
Topic:
Enviornmental data analysis and modelling
Climate change and its impact on everyday life still remains one of the greatest challenge of our era. The complex nature of climate data addresses the use of data science techniques to provide predictive analytics to the task at hand. While most existing approaches exploit correlation between...Read more

AN INTEGRATED APPROACH FOR THE ASSESSMENT OF CONSTRUCTED WETLANDS OPERATIONAL EFFICIENCY, USING BOTH CHEMICAL AND BIOLOGICAL DATA
(Corresponding) Dailianis S., Charalambous N., Foiniris S., Komodromou A., Cocilovo C., Dormousoglou M., Lyberatos G., Ntaikou I.
Topic:
Wastewater treatment
The present study evaluated the operational efficiency of a constructed wetland (CW) located at Andritsaina/Krestena municipality (Western Greece, Peloponnese, Greece), using a battery of tests and bioassays. Specifically, raw WWs entering the CW basins with broadleaf cattail Typha latifolia (raw-...Read more

Quantitative and qualitative assessment of food waste of the hospitality sector in Greece
Lasaridi K., Manios T., (Corresponding) Abeliotis K., Terzis E., Chroni C., Galliou F., Panteli V.
Topic:
Food waste
In Greece, approximately 1.8 million tonnes of food waste are generated each year, mostly disposed of in landfill. Food waste is of concern for businesses in the hospitality and food service sectors, which in Greece dispose of an estimated 100,000 tonnes of food waste annually, almost 6% of the...Read more
A system dynamics model to quantify the impacts of restoration measures on the water-energy-food nexus in the Urmia lake Basin, Iran
Bakhshianlamouki E., Masia S., Karimi P., van der Zaag P., (Corresponding) Susnik J.
Topic:
Water, energy and/or food nexus
Water scarcity exacerbated by growing demand has created environmental, social, and economic challenges in the Urmia Lake Basin (ULB), Iran. Tackling these requires an integrated approach. A System Dynamics Model is developed simulating the water-energy-food nexus in the ULB as a holistic multi-...Read more
