Guimarães 2030: A new governance ecosystem
Loureiro I., (Corresponding) Ribeiro C., Sepúlveda D.
Topic:
Environmental management and policies
Nowadays there is near consensus that cities have an important role to play in the pursuit of global climate protection and Sustainability. However, local strategies for sustainable development require a holistic and systemic approach, enabling multiscale involvement dynamics from a variety of...Read more
Implementation of flow duration curves for evaluating the environmental flow
(Corresponding) Lagogiannis S., Bournas A., Hatzigiannakis E., Baltas E.
Topic:
Hydrology and water resources
In this research work, the implementation of Flow Duration Curves (FDC) was assessed, as a mean of estimating the environmental flow (e-flow) in rivers segments in Greece. The FDC of fifteen river basins varying in size and geomorphological characteristics and covering a wide area of mainland...Read more
Application of a GIS based distributed model for rainfall runoff simulations
(Corresponding) Andrikopoulou T., Bournas A., Baltas E.
Topic:
Hydrology and water resources
In this research work, the development and application of a distributed rainfall – runoff model, to be used in flood related simulations was performed. The model utilizes the time–area diagram theory in order to calculate and route the runoff of each grid to the basin’s outlet. The selected study...Read more

Development of an urban resilience indicator for Athens in the context of climate change
(Corresponding) Polydoros A., Mavrakou T., Cartalis C.
Topic:
Climate change mitigation and adaptation
Urbanization interacts with climate change through the way cities are organized and built (land cover/ land use, urban morphology). Increased energy consumption and consequently CO2 emissions, combined with emissions from city functions (urban metabolism, anthropogenic heat sources) intensify urban...Read more
Investigating the effect of different NaCl concentrations as draw solution used to concentrate synthetic municipal wastewater in a Forward Osmosis system
(Corresponding) Kappa S., Themeli E., Noutsopoulos C., Malamis S.
Topic:
Wastewater treatment
The main bottleneck towards resource and energy valorization of municipal wastewater is the low strength of sewage; characterized by low organic matter and nutrient concentrations. In this study, a bench scale Forward Osmosis (FO) system with a cellulose triacetate membrane (CTA) was used as a pre-...Read more

Are emerging contaminants affecting drinking water microbial biofilms?
(Corresponding) Gomes I., Pinto I., Arruda V., Simões L., (Corresponding) Simões M.
Topic:
Drinking water safety
The presence of biofilms in drinking water (DW) distribution systems is unavoidable as well as the presence of trace levels of different emerging contaminants (ECs). ECs constitute a potential risk for the “One Health” trilogy. In particular, the presence of antibiotics in the environment has been...Read more
Investigation of the performance of green nano Zero Valent Iron for the removal of emerging contaminants from water
(Corresponding) Panagou I., Noutsopoulos C., Barka E., Mystrioti C., Koumaki E., Mamais D., Papassiopi N., Malamis S.
Topic:
Emerging pollutants
Nano Zero Valent Iron (nZVI) is considered as a promising nanomaterial for the removal of a wide range of recalcitrant pollutants from contaminated water and soil. Due to its high reactivity, large surface area, its catalytic and reductive properties along with the ability to be produced at low...Read more
Keywords:
nano zero valent iron, green synthesis, endocrine disrupting chemicals, pharmaceuticals, emerging contaminants
Material flow analysis applied to a waste treatment plant in Lombardy (Italy)
(Corresponding) Castro F., Fabbri M., Vaccari M., Cutaia L.
Topic:
Solid waste management
Material flow analysis (MFA) allows to quantify inputs, outputs and stocks of a system and to communicate results visually. It can be used for calculating process effectiveness, losses and for identifying critical points within a system, being useful for strategically intervening in a corporative...Read more
Pilot-scale membrane bioreactor for wastewater treatment using innovative encapsulated self-forming dynamic membrane
Castrogiovanni F., Borea L., HASAN S., Belgiorno V., (Corresponding) Naddeo V.
Topic:
Wastewater treatment
The use of membrane bioreactors (MBR) is a promising technique for wastewater treatment that manages to respect the restrictive limits imposed by regulations.
However, during the filtration process membranes are subject to fouling which requires additional costs for cleaning and replacing the...Read more

In-situ bioremediation of groundwater polluted with Cr(VI) under anaerobic conditions
Galani A., Anastopoulou P., Noutsopoulos C., (Corresponding) Mamais D.
Topic:
Soil and groundwater contamination and remediation
The natural capacity of several microbes to reduce Cr(VI) to Cr(III) has been considered of much interest in order to remediate soil and groundwater polluted with Cr(VI). The objective of this work is to evaluate the enhancement of the activity of indigenous Cr(VI) reducing bacteria by the addition...Read more
