Basic Principles of a DSS Tool Developed to Prioritize NRW Reduction Measures in Water Pipe Networks
(2015)Non-revenue water (NRW) in urban water distribution networks is a very demanding task to handle. NRW impacts are economic (lost revenues), environmental (water and energy losses) and social (inefficient water pricing ... -
Basin-wide actual evapotranspiration estimation using NOAA/AVHRR satellite data
(2005)The present study elaborates on the estimation of actual evapotranspiration at watershed scale using mathematical models and remote sensing techniques. A water balance model was updated and used to simulate runoff from a ... -
Cellular-automata and individual-based approaches for the modeling of biofilm structures: Pros and cons
(2010)Fresh water shortage is one of the greatest problems of modern society; as a result, water desalination, particularly with membrane processes, is becoming increasingly important, since it makes possible the use of brackish ... -
Climatic impacts on the runoff generation processes in British Columbia, Canada
(2002)The potential impact of future climate change on runoff generation processes in two southern British Columbia catchments was explored using the Canadian Centre for Climate Modelling Analysis General Circulation Model ... -
Comparison and assessment of the monitoring data of two REMOS stations in Nestos and Pagoneri for the year 2004. The base for an integrated water management
(2009)The monitoring results of two "REMOS" telemetric stations, in River Nestos, are compared. The first one is situated at the Nestos Delta, near Hrisoupoli (Remote Station - RS "Nestos"), and the second one is situated at the ... -
Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
(2004)This project is concerned with the comparison of two algorithms used in groundwater management models based on Quadratic Programming (QP) and Non-linear Programming (NLP) models,. A quadratic objective function is used and ... -
Cotton yield estimation based on NOAA/AVHRR produced NDVI
(2001)The high temporal resolution of the NOAA/AVHRR satellite data can provide an efficient and consistent way for biomass and yield monitoring and assessment. The reflected radiation provides an indication of the type and ... -
DAILY PRECIPITATION VARIABILITY IN SEMIARID AGRICULTURAL REGIONS IN MACEDONIA, GREECE
(1995)The spatio-temporal variability of daily precipitation series was investigated in a semiarid region of central Macedonia in northern Greece. Ten years of daily rainfall records for seven stations in the region constituted ... -
Decolorization and degradation of reactive azo dyes via heterogeneous photocatalytic processes
(2010)Reactive dyes are extensively used in textile industry in the last years due to their superior performance, but they are environmentally hazardous and difficult to treat effectively by classical methods. In the present ... -
Defining the level of the Non-Revenue Water in Kozani, Greece: is it a typical case?
(2015)Water Losses in pipe networks usually represent the biggest "water use" due to the high leakage occurring. Water utilities are forced to apply effective Non-Revenue Water (NRW) reduction strategies, as climate change ... -
Desalination and Water Treatment
(2012) -
Desalination by mechanical compression of humid air
(1999)A novel desalination concept is described, combining the principles of humidification-dehumidification and mechanical vapor compression. Thermodynamic analysis indicates the effect of operating conditions on water production ... -
Design of optimal irrigation networks
(2006)The problem of selecting the best pattern of pipe diameters of an irrigation network has long been given considerable attention by engineers when designing hydraulic works. The classical optimization techniques, which have ... -
Domestic water pricing in Greece: a spatial differentiation
(2015)This study investigates the differentiation of the water pricing policies applied by the Greek Municipal Water Utilities (GMWU) in several regions. GMWU are being characterized by individual management framework with a ... -
The DPSIR Approach for an Integrated River Management Framework. A Preliminary Application on a Mediterranean Site (Kalamas River -NW Greece)
(2012)The European Water Policy introduced the necessity to apply new methodological approaches for the sustainable management of water resources. In the present paper the Driving-Pressure-State-Impact-Response (DPSIR) framework ... -
Ecological footprint as a tool for integrated coastal zone management
(2013)The Ecological Footprint (EF) is a widely accepted tool for translating all human activities so as to assess their environmental impact and has been often used as an indicator for environmental sustainability, over the ... -
ECOLOGICAL MONITORING STUDIES, FOR VOLOS SEA OUTFALL (PAGASSITIKOS-GULF, WESTERN AEGEAN SEA)
(1995)Nutrient pollution in Pagassitikos Gulf arises mainly from the disposal of Volos untreated domestic wastewater inside Volos Bay, and also the agricultural run-off from the surrounding the Gulf cultivated areas. Volos Bay's ... -
THE ECOLOGICAL STATE OF THE ELEFSIS BAY PRIOR TO THE OPERATION OF THE ATHENS SEA OUTFALL
(1994)Nutrient pollution in Elefsis Bay arises mainly from the disposal of Athens untreated wastewater at the eastern entrance of the Bay. The absence of river discharge, lack of cultivated agricultural areas providing runoff ... -
Ecosystem simulation modeling of nitrogen dynamics in the restored lake Karla in Greece
(2011)Restored lakes are complex dynamic ecosystems. Ecosystem-level modeling of the processes that take place in a lake is a useful tool for understanding lake function and structure and for making predictions. A nitrogen ...
