This study proposes a simple method to produce flood hazard assessment map in burned and urban areas, where primary data are scarce. The area is municipal unit of Nea Makri, coastal part the eastern Attica peninsula (central Greece), which has been strongly urbanized suffered damage from fires 2018. Six factors were considered as parameters most controlling runoff when it overdraws drainage system’s capacity. analytical hierarchy process (AHP) geographical information system (GIS) utilized...

The achievement of sustainable development goals in groundwater resources related to water quality issues is a critical question many regions. This study aims combine powerful tools for helping stakeholders and policymakers achieve agricultural areas. DPSIR (Driver–Pressure–State–Impact–Response) model combination with the Canadian Council Ministers Environment Water Quality Index Groundwater Directive 2006/118/European Community—Threshold Values was applied using hydrogeochemical dataset...

Abstract Wastes are usually thought of as unwanted or unusable materials. Waste is any substance which discarded after primary use, considered worthless, defective, and no use. The term often subjective, not every application has identical raw material requirements sometimes even objectively inaccurate. A starting point towards managing waste the division in basic categories, ranging from municipal agricultural to radioactive explosive waste. Through proper collection solid waste, very...

Until now, there was no simple procedure to test the performance of water quality indices (WQIs) or, in other words, perform their meta-evaluation. The purpose this study is provide a meta-evaluation approach two widely used WQIs and suggestions for selecting one or both them application groundwater assessment as proposed by European Union. concept based on testing known applying classification Water Framework Directive (WFD; 2000/60/EC) Groundwater (GWD; 2006/118/EC) which reference....

Karst features such as polje are highly vulnerable to natural and anthropogenic pollution. The main objectives of this study were investigate the soil quality in Ioannina (north-west Greece) concerning arsenic (As) zinc (Zn), delineate their origin well compare As Zn content with criteria recorded literature. For purpose, geomorphological settings, land use, physicochemical properties mapped evaluated, including texture concentrations aqua-regia extractable Zn. concentration elements was...

Globally, groundwater is a valuable natural resource that may be relied upon for irrigation and drinking needs. The main purpose of this study to investigate the geochemistry in West El Qusiya, Assuit, Egypt. Groundwater suitability has been estimated with some methods, instance, electrical conductivity (EC), sodium adsorption ratio (SAR), residual carbonate (RSC), Killey (KR), magnesium hazard (MH), permeability index (PI), Piper trilinear diagram, USSL diagram. diagram shows potassium...

The primary goal of this study is to analyze the hydrogeochemical properties and assess groundwater quality for drinking, domestic, irrigation purposes in West El Minia, Egypt. Major components were determined 49 samples evaluate water area. Principal component analysis (PCA), hierarchical cluster (HCA), geostatistics, spatial mapping used identify chemical processes that influence highlight areas health risks. According TDS values, about 22% are suitable drinking. Due elevated values...

The global need for energy has risen sharply recently. A shift to clean is urgently needed avoid catastrophic climate impacts. Hydrogen (H2) emerged as a potential alternative source with near-net-zero emissions. In the African continent, sustainable access and transition away from fossil fuels, this paper presents new approach through which waste can produce green hydrogen biomass. Bio-based employing organic biomass recommended using biological (anaerobic digestion fermentation) processes...

This study aims to assess the vulnerability of groundwater in Nile Delta contamination and evaluate its suitability for drinking irrigation. A total 28 wells (ranging from 23 120 m depth) two surface water samples were analyzed dissolved solids (TDS), heavy metals, quality index (GWQI), hazard quotient (HQ). The findings reveal that deep (60–120 m) displays paleo-water characteristics, with low TDS, hardness, minimal metal contamination. In contrast, shallow (<60 is categorized into three...

Assessing the suitability of urban and agricultural land is essential for planning sustainable systems. The main objective this study to evaluate in Ioannina plain (western Greece) concerning soil contents two potentially toxic elements, cadmium (Cd) cobalt (Co). Geochemical spatial analysis methods were applied assess distribution Cd Co identify their origin. primary anthropogenic sources topsoil area can be attributed traffic emissions, aircraft operations, vehicle crushing dismantling...

In this research, a new machine-learning approach was proposed to evaluate the effects of eight input parameters (surface area, relative compactness, wall overall height, roof orientation, glazing area distribution, and area) on two output parameters, namely, heating load (HL) cooling (CL), residential buildings. The association strength each parameter with systematically investigated using variety basic statistical analysis tools identify most effective important variables. Then, different...

This study presents an overview about the arsenic (As) contamination and its sources in two European countries. Arsenic is a highly toxic element inorganic form it carcinogenic to human seven low concentrations. The occurrence of As surface water, stream marine waters, groundwater, bottled sediment, soil, mines, seafood, environmental origin, impacts on health are discussed. classes Geoaccumulation Index for Greece ranges from practically uncontaminated extremely contaminated, Cyprus varies...

Rainwater Harvesting system (RWHs) can be considered as an alternative water resource in the era of climate crisis. This research aims to study effectiveness a RWHs for domestic non-potable use and demand community Mediterranean site (Chios island, Greece). A balance model is applied simulate behavior rainwater tank calculate daily savings. The analysis correlates capacity, catchment area population. operation collection has been calculated seven years. In order assess investment risk...

Water quality indices (WQIs) are efficient tools, globally used for the determination of status water bodies. In Greece, almost a decade, physicochemical in rivers has been determined by rigorous, biologically-based, national classification system, developed Hellenic Centre Marine Research (HCMR), through calculation simple index (HWQI) that takes into account six parameters: five nutrient species and dissolved oxygen. Taking HWQI as reference, present study attempts to implement Canadian...
