Climate change implications on flood response of a mountainous watershed
(2004)The modification of the flood response due to future climate change is presented for the Illecillewaet watershed of British Columbia, Canada. The Canadian Centre for Climate Modeling Analysis General Circulation Model ... -
Combining pressure management and energy recovery benefits in a water distribution system installing PATs
(2017)Gravity can play a beneficial role in certain water distribution networks (WDNs), although sometimes high nodal pressures occur. Excessive pressure may lead to several negative effects regarding the network's operation and ... -
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 ... -
Groundwater nitrate contamination integrated modeling for climate and water resources scenarios: The case of Lake Karla over-exploited aquifer
(2019)Groundwater quantity and quality degradation by agricultural practices is recorded as one of the most critical issues worldwide. This is explained by the fact that groundwater is an important component of the hydrological ... -
Heating and cooling induced stresses and displacements in heat exchanger piles in sand
(2020)Heating and cooling of heat exchanger piles causes changes in the axial stresses in the pile and vertical pile displacements. Changes in axial stress (thermal stresses) are more significant in the case of fixed head piles, ... -
Integrated Modeling of Agronomic and Water Resources Management Scenarios in a Degraded Coastal Watershed (Almyros Basin, Magnesia, Greece)
(2022)The scope of this study is to assess the effects of agronomic and water resources management scenarios on groundwater balance, seawater intrusion, and nitrate pollution and the comparison of the developed scenarios relative ... -
An integrated modeling system for the evaluation of water resources in coastal agricultural watersheds: Application in almyros basin, thessaly, greece
(2021)This study presents an integrated modeling system for the evaluation of the quantity and quality of water resources of coastal agricultural watersheds. The modeling system consists of coupled and interrelated models, ... -
Inter-comparison of statistical downscaling methods for projection of extreme flow indices across Europe
(2016)The effect of methods of statistical downscaling of daily precipitation on changes in extreme flow indices under a plausible future climate change scenario was investigated in 11 catchments selected from 9 countries in ... -
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 ... -
A lumped conceptual approach for modeling hydrological processes: the case of Scopia catchment area, Central Greece
(2017)In the catchment area of Scopia, Central Greece, a lumped applied approach of water balance was accomplished, by applying the Zygos model, which delineates an essential water balance forms. The model is in view of Thornthwaite ... -
Mathematical modeling of trophic state and nutrient flows of Lake Karla using the PCLake model
(2015)In the present article, we simulate Lake Karla, an important natural ecosystem under restoration in Greece, operating also as a reservoir. The lake trophic state is characterized as hypertrophic with the expected negative ... -
Optimizing the formation of DMAs in a water distribution network through advanced modelling
(2019)Water pressure management in a water distribution network (WDN) is a key component applied to achieve desirable water quality as well as a trouble-free operation of the network. This paper presents a hybrid, two-stage ... -
Stochastic nitrate simulation under hydraulic conductivity uncertainty of an agricultural basin aquifer at Eastern Thessaly, Greece
(2021)Lake Karla Watershed is an agricultural basin characterized by intense agricultural activities, which lead to quantitative and qualitative aquifer degradation. The exploitation of non-renewable groundwater resources and ... -
Usage of statistical modeling techniques in surface and groundwater level prediction
(2020)The paper presents a thorough evaluation of the performance of different statistical modeling techniques in ground- and surface-level prediction scenarios as well as some aspects of the application of data-driven modeling ... -
The use of the pilot points method on groundwater modelling for a degraded aquifer with limited field data: The case of Lake Karla aquifer
(2021)Groundwater depletion poses a major threat to global groundwater resources with increasing trends due to natural and anthropogenic activities. This study presents a surface-groundwater framework for water resources modelling ...
