2D and 3D soil moisture imaging using a sensor-based platform moving inside a subsurface network of pipes
(2013)In this study a prototype sensor-based platform moving inside a subsurface network of pipes with the task of monitoring the soil moisture content is presented. It comprises of a mobile platform, a modified commercial soil ... -
Accurate water demand spatial allocation for water networks modelling using a new approach
(2015)The paper presents an alternative approach regarding the spatial allocation of the actual water demand (at node level) when developing a pipe network's hydraulic simulation model. The process takes into account the respective ... -
Adsorption of methylene blue and methyl red dyes from aqueous solutions onto modified zeolites
(2013)Zeolite, hematite, modified zeolite and commercial activated charcoal were examined for their ability to remove methylene blue (MB) and methyl red (MR) from their aqueous solutions. Modified zeolite and hematite were ... -
Allocating the cost of the carbon footprint produced along a supply chain, among the stakeholders involved
(2014)Greenhouse gas emissions are widely considered nowadays one of the main causes for global climate change. Every product's supply chain consists of several energy usage processes. Three new approaches (end-userpays; production ... -
Analysis and evaluation of the operational status of municipal wastewater treatment plants in the Dodecanese prefecture in Greece
(2011)Data from municipal and private wastewater treatment plants (WWTP) in the Dodecanese prefecture in Greece was collected via a questionnaire and personal interviews, and was analyzed with respect to the operational status ... -
Analysis of seawater microbiological quality data in Greece from 1997 to 2006: association of risk factors with bacterial indicators
(2009)This study deals with the examination of quality of seawater bathing areas in Greece over a 10-year period and identifies risk factors for high bacteria indicator organism concentrations. Qualitative descriptive analysis ... -
Application of leaching tests for toxicity evaluation of coal fly ash
(2006)The toxic properties of coal fly ash samples obtained from various coal combustion power plants were evaluated in this work using physicochemical analyses and bioassays. Physicochemical analyses showed that heavy metals ... -
Application of the Sebs Water Balance Model in Estimating Daily Evapotranspiration and Evaporative Fraction from Remote Sensing Data Over the Nile Delta
(2011)Estimation of evapotranspiration is always a major component in water resources management. The reliable estimation of daily evapotranspiration supports decision makers to review the current land use practices in terms of ... -
Assessing the performance of urban water networks across the EU Mediterranean area: The paradox of high NRW levels and absence of respective reduction measures
(2013)The aim of this paper is to assess the performance level of water distribution systems (WDS) in six areas located in four Mediterranean countries, and evaluate their common characteristics. The second modification of the ... -
Assessment and Modelling of Groundwater Quality Data by Environmetric Methods in the Context of Public Health
(2010)Various chemometric methods were used to analyze and model potable water quality data. Twenty water quality parameters were measured at 164 different sites in three representative areas (low land, semi-mountainous, and ... -
Assessment of NDVI and agrometeorological indices for major crops in central Greece
(2002)Major agricultural crops such as vineyards and apples can be monitored by comparing normalized difference vegetation index (NDVI) with several agrometeorological indices. The agrometeorological indices used in this study ... -
Assessment of nutrients and heavy metals in the surface sediments of the artificially lake water reservoir Karla, Thessaly, Greece
(2015)In this research, the sediment quality of the recently reconstructed Lake Karla (central Greece) was evaluated by monitoring the nutrient loadings and heavy metal concentrations in 16 sites during the initial period of the ... -
Assessment of pressures and impacts on surface water bodies of the Mediterranean. Case study: Pamvotis Lake, Greece
(2013)The aim of the study presented in this article is to assess the ecological status of a surface water body in the Mediterranean using the methodological approach of Driver-Pressure-State-Impact-Response. Based on this ... -
Assessment of remotely sensed drought features in vulnerable agriculture
(2012)The growing number and effectiveness of Earth observation satellite systems, along with the increasing reliability of remote sensing methodologies and techniques, present a wide range of new capabilities in monitoring and ... -
Assessment of the Typology and the Trophic Status of Two Mediterranean Lake Ecosystems in Northwestern Greece
(2014)The objective of this study is the assessment of the typology and the trophic relevant water quality parameters in two Mediterranean lakes (Lake Ziros and Lake Kastoria) under the view of the WFD. Lake types were identified ... -
Assessment of vulnerable freshwater ecosystems and various aquatic effluents by means of ecotoxicological assays
(2015)A battery of ecotoxicological assays of different trophic chain levels has been performed for water and sediment samples of two Greek vulnerable freshwater ecosystems (Karla Lake in Thessaly Region and Koronia Lake in ... -
An assessment of water quality in a coastal embayment (Phaleron bay, Greece)
(1995)Athens basin drains by gravity to the coast into the Phaleron Bay by the Kifissos river. The Phaleron coast is currently undergoing extensive remodelling and is scheduled for development as a major amenity and recreational ...
