Comparative Study of Flow through Vegetation Stems With and Without Foliage
(Corresponding) Christodoulou G., Mavrommatis A.
Topic:
River systems in diverse climates and environments
The presence of vegetation in rivers, streams and riparian zones affects significantly the flow field and consequently the resistance, pollutant dispersion, sediment transport and ecological habitat. In this paper, a comparative study is undertaken to investigate the effect of an array of simple...Read more

Overrated Credence to the Outdated Sand Mining Legislations - A hydrologically challenged measure
Varadharajan S.
Topic:
Hydrology and water resources
The recent floods in the 'God's own Paradise'(Kerala) reminds the Indian Sub-Continent as well as the Global spectators of not just heavy rainfall but also the 'hungry water effect' from deranged desiltation. Laws from the first decade of independence...Read more
High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification
Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.
Topic:
Environmental biotechnology and bioenergy
Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more
A comparative evaluation of urban metabolism methodologies
(Corresponding) Voukkali I., ZORPAS A.
Topic:
City metabolism or areas metabolism
Globally, urban metabolism analysis has become a significant tool for the study of urban ecosystems. Urban metabolism as a concept represents an integrated platform for analyzing the urban dynamics and supporting the planning processes in cities as social-ecological systems within the concept 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
Groundwater Flow Dynamics in Shallow Coastal Plain Sands Aquifer, Abesan Area, Eastern Dahomey Basin, Southwestern Nigeria.
Joseph A.
Topic:
Soil and groundwater contamination and remediation
Thirty hand-dug wells were identified and evaluated to study the groundwater flow dynamics and anionic species distribution in the study area. Topography and water table levels method with the aid of Surfer were adopted in the delineation of six recharge and discharge zones correspondingly...Read more
Assessing the performance of green nano Zero Valent Iron in column experiments for the removal of NSAIDs from water
(Corresponding) Panagou I., Kalli M., Noutsopoulos C., Mamais D., Koumaki E., Malamis S.
Topic:
Emerging pollutants
The existence of emerging contaminants in the aquatic environment is globally a major concern. Among them, non-steroidal anti-inflammatory drugs (NSAIDs) are a vast category of pharmaceuticals that are widely consumed and cannot be completely removed in typical wastewater treatment systems, thus...Read more

Analysis of the extreme water phenomenon (hydrological drought) in the small river basins in NE Romania
(Corresponding) PAVELUC L., GROZAVU A., HUTANU E., MIHU-PINTILIE A.
Topic:
Hydrology and water resources
This paper presents an analysis of one of the climatic dangers experienced in recent times is the high intensity of the drought phenomenon on small rivers in NE Romania that affects society and ecosystems. As a case study, it is intended to identify statistically significant trends in the minimum...Read more

ANALYSIS OF THE 0.1% AND 1% FLOODBANDS RELATING TO THE NV AREA OF THE CEAHLAU MASSIVE, THE CONFLUENCE SECTOR OF THE BISTRIȚA RIVER WITH HIS TRIBUTARY - BISTRICIORA RIVER
(Corresponding) Hutanu E., Linu-Stoilov V., Paveluc L., Stoleriu C., Mihu_Pintilie A., Grozavu A.
Topic:
Hydrology and water resources
The study aims to outline the flood potential of a mountainous area, in the context of simulating flooded areas, GIS techniques being essential in determining the spatial and probabilistic impact of this type of hydrological phenomena. The resulting modeling highlights the floodplains and the...Read more
Comparative evaluation of three different membranes for the treatment of a brewery and a dairy treatment effluent
(Corresponding) Plevri A., Gkoumas F., Koumaki E., Noutsopoulos C., Mamais D., Nikolaou M., Magraritis M., Malamis S.
Topic:
Circular economy and industrial symbiosis
A laboratory-scale system with a capacity of 7L/h consisting of three different ultrafiltration membranes operating alternatively, was designed and installed at the Sanitary Engineering Laboratory (SEL) facilities. The purpose of this membrane system was to test the performance of alternative...Read more
