Anthropogenic effects on bacterial diversity and function along a river-to-estuary gradient in Northwest Greece revealed by metagenomics
(2016)Studies assessing the effects of anthropogenic inputs on the taxonomic and functional diversity of bacterioplankton communities in lotic ecosystems are limited. Here, we applied 16S rRNA gene amplicon and whole-genome ... -
Drought Assessment in Nestos River Basin (N. Greece) for the Period 1955-2018
(2022)Drought is a significant meteorological phenomenon that can seriously impact natural ecosystems. Drought assessment and monitoring should be continuous in regions of high ecological importance, for the conservation of ... -
Environmental DNA detection of giant snakehead in Thailand’s major rivers for wild stock assessment
(2022)Capture-based aquaculture is now gaining much attention in Southeast Asia. This system was used to produce several fish species with social and economic implications, including the giant snakehead (Channa micropeltes). As ... -
Fatigue failure of buckled pipelines
(2004)Quite often, steel buried pipelines exhibit local buckles due to imposed deformations, which may cause failure because of fatigue from repeated loading. When such buckles are detected in a steel pipeline, a decision must ... -
A flood inundation modeling approach for urban and rural areas in lake and large-scale river basins
(2021)Fluvial floods are one of the primary natural hazards to our society, and the associated flood risk should always be evaluated for present and future conditions. The European Union’s (EU) Floods Directive highlights the ... -
Health risk assessment of potentially toxic elements in soils along the Central Elbe River, Germany
(2019)Floodplain soils across Central Elbe River (CER), Germany, vary considerably in potentially toxic element (PTE) content. However, there has never been a comprehensive study that links PTE levels with human health risk for ... -
Investigation of the Optimum Connection of a Fish Pond with the Adjacent Main Riverine Flow
(2016)The optimum design of the opening through which a fish refuge pond communicates laterally to the main flow of a river was investigated. The study was based on the realization of physical and mathematical models. The physical ... -
Joint modelling of flood peaks and volumes: A copula application for the Danube River
(2016)Flood frequency analysis is usually performed as a univariate analysis of flood peaks using a suitable theoretical probability distribution of the annual maximum flood peaks or peak over threshold values. However, other ... -
Micromixing efficiency of particles in heavy metal removal processes under various inlet conditions
(2019)Water quality problems are a persistent global issue since population growth has continually stressed hydrological resources. Heavy metals released into the environment from plating plants, mining, and alloy manufacturing ... -
Mixing of Fe3O4 nanoparticles under electromagnetic and shear conditions for wastewater treatment applications
(2022)The ability of heavy metals to accumulate in living organisms, combined with the fact that they are not biodegradable, necessitates an expansion and improvement of the existing water purification methods. An effective ... -
A novel method for the automatic extraction of quality non-planar river cross-sections from digital elevation models
(2020)Flood simulation and hydrodynamic modeling of river flow require a dense sequence of river cross-sections. These cross-sections should be perpendicular to the flow path and are usually obtained through an in-field survey ... -
Numerical study of particle transport in a river with a lateral harbor basin
(2017)In this study, the development and application of two mathematical models used to investigate particle transport in a river with a lateral harbor basin are presented: a two-dimensional depth-averaged hydrodynamic model and ... -
Quantifying the changes in genetic diversity within sequence-discrete bacterial populations across a spatial and temporal riverine gradient
(2019)Recent diversity studies have revealed that microbial communities of natural environments are dominated by species-like, sequence-discrete populations. However, how stable the sequence and gene-content diversity are within ... -
Reputation-assisted utility maximization algorithms for peer-to-peer networks
(2008)Peer-to-peer networks are voluntary resource sharing systems among rational agents that are resource providers and consumers. While altruistic resource sharing is necessary for efficient operation, this can only be imposed ... -
Waste management in Larissa prefecture, Greece
(2004)It is the objective of this study to evaluate the management of air waste, wastewater and solid waste in the prefecture of Larissa, Greece. The levels of air pollution in the prefecture are not so high. Nevertheless, ...
