Effect of the dependence structure and time irreversibility of streamflow in flood inundation mapping with focus on the long-term persistence behaviour

(Corresponding) Dimitriadis P., Iliopoulou T., Papanicolaou P., Koutsoyiannis D.
Topic: 
Floods, droughts and water scarcity
The marginal structure of streamflow, with focus on the right tail behaviour, is considered as the main factor in flood risk assessment, while little is known on the effect of the temporal dependence structure and irreversibility of streamflow. Interestingly, the second-order dependence behaviour...Read more

A stochastic approach to resilience assessment of urban water systems from source to tap.

(Corresponding) Nikolopoulos D., Kossieris P., Makropoulos C.
Topic: 
Hydrology and water resources
The design of urban water systems faces long-term uncertainties in a multitude of parameters, from the hydroclimatic and socioeconomic realms, such as population growth, climate change and shifting demand patterns. To analyze such systems in a holistic way, many models for sub-systems are typically...Read more

Degradation of textile dyes in water by gas-liquid NSP-DBD plasma

MEROPOULIS S., (Corresponding) AGGELOPOULOS C.
Topic: 
Advanced oxidation processes
Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more

Synthesis of self-assembled graphene oxide (GO)/manganese oxide (MnO2) sulfonated-polyethersulfone (SPES) membranes for heavy metal removal from wastewater

Ibrahim Y., Wadi V., Ouda M., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic: 
Wastewater treatment
As the 21st century continues, water scarcity remains a significant burden to overcome in many regions. The treatment of industrial wastewater has great potential in providing adequate quantities of freshwater. To ensure safe usage of this water, heavy metal ions must be removed to avoid their...Read more

Citizens' awareness and education for tackling microplastic contamination in freshwater ecosystems

(Corresponding) Rodrigues C., Ribeiro A., Silva N., Silva A., Gravato C., Ribeiro C.
Topic: 
Case studies of macro- and microplastics pollution in coastal waters and rivers
Microplastics (MPs) are ubiquitous and persistent contaminants, particularly in river sediments reaching high abundances with potential to impair ecosystem functions and services of great importance to humankind. Thus, monitoring programmes and public awareness are pivotal to implement mitigation...Read more

Affordable multi-spectral imaging system for the identification and classification of microplastics from the environment

(Corresponding) Konde S., Gonnade V., Brackmann S., Nguyen J., Schneider M., Loeschel L., Lott C., Weber M., Koch M.
Topic: 
Case studies of macro- and microplastics pollution in coastal waters and rivers
Studies on microplastic pollution commonly use expensive spectroscopic methods such as FTIR spectroscopy or Raman spectroscopy. Alternatively, studies could also employ cheaper methods such as optical microscopes, which are prone to errors. Here, we present an inexpensive and simple multi-spectral...Read more
