3-D simulations of flows in the reconstituted lake Karla, Thessaly, Greece
(2010)We report on three-dimensional flow simulations carried out in order to describe the dominant water current patterns in the reconstituted lake Karla. The flow is considered to be generated mainly by wind shear while the ... -
Comparison of ARIMA and Transfer Function (TF) models in Water Temperature simulation in dam - Lake Thesaurus, eastern Macedonia, Greece
(2010)In the present work, two modelling and forecasting techniques were evaluated on the basis of: a) their efficiency to forecast and b) their ability to utilize auxiliary environmental information: ARIMA and Transfer Function ... -
Deep learning in water resources management: The case study of Kastoria lake in Greece
(2021)The effects of climate change on water resources management have drawn worldwide attention. Water quality predictions that are both reliable and precise are critical for an effective water resources management. Although ... -
Design and implementation of a hybrid model based on two-layer decomposition method coupled with extreme learning machines to support real-time environmental monitoring of water quality parameters
(2019)Accurate prediction of water quality parameters plays a crucial and decisive role in environmental monitoring, ecological systems sustainability, human health, aquaculture and improved agricultural practices. In this study ... -
Development of a district information system for water management planning and strategic decision making
(2015)The overall objective of this work is the development of a District Information System (DIS) which could be used by stakeholders for the purposes of a district day-to-day water management as well as for planning and strategic ... -
Estimation of crop water requirements using remote sensing for operational water resources management
(2015)An integrated modeling system, developed in the framework of "Hydromentor" research project, is applied to evaluate crop water requirements for operational water resources management at Lake Karla watershed, Greece. The ... -
Evaluation of Water Resources Management Strategies to Overturn Climate Change Impacts on Lake Karla Watershed
(2016)The effects of climate change on meteorology, hydrology and ecology have become a priority area for research and for water management. It is crucial to identify, simulate, evaluate and, finally, adopt water resources ... -
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 modeling and management in a complex lake-aquifer system
(2007)In this paper, the hydrogeologic analysis and the development of a numerical model for the simulation of a complex system of aquifers in Northern Greece are presented. The study area faces a severe environmental danger as ... -
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 ... -
Hazardous toxic metal(loid)s in top- and deep-soils during the transformation of aquaculture ponds restored to farmland
(2022)The pollution risks due to the soil migration of toxic metal(loid)s (TMs) are a greatly hazard to ecological environment as well as animal and human health. Previous studies have primarily focused on surface contamination ... -
Hazards that threaten Greek wetlands: The case of Lake Koronia
(2008)Wetlands all over the world have been recognized as some of the most productive, multifunctional and dynamic ecosystems and they are under protection according to European Union legislation. However, they are under imminent ... -
The "hidden cost" of renewable energy sources in electricity pool markets
(2012)The aim of this paper is to explore the "hidden cost" associated with the uncertainty in power generation that Renewable Energy Sources (RES) introduce in electricity pool markets. This cost, which is additional to the ... -
Hydrologic processes simulation using the conceptual model Zygos: the example of Xynias drained Lake catchment (central Greece)
(2016)In the catchment of Xynias drained Lake, hydrologic processes simulation took place using a lumped approach with the conceptual model Zygos. The model implements a conceptual soil moisture accounting scheme extended with ... -
Implementation of the Water Framework Directive: Lessons Learned and Future Perspectives for an Ecologically Meaningful Classification Based on Phytoplankton of the Status of Greek Lakes, Mediterranean Region
(2019)The enactment of the Water Framework Directive (WFD) initiated scientific efforts to develop reliable methods for comparing prevailing lake conditions against reference (or nonimpaired) states, using the state of a set ... -
Integrated Hydro-Economic Modeling for Sustainable Water Resources Management in Data-Scarce Areas: The Case of Lake Karla Watershed in Greece
(2019)Hydro-economic models can serve as valuable tools to improve the understanding of system details, as well as to support decision-making and water resources management. However, hydro-economic models are not practically ... -
Investigation of factors affecting the trophic state of a shallow Mediterranean reconstructed lake
(2017)In this article, we focus on shallow sub-tropical lakes and study the factors that determine their trophic state and food web structure. We use the model PCLake to simulate lake nutrient dynamics and investigate key factors ... -
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 ... -
Machine learning approaches for predicting health risk of cyanobacterial blooms in Northern European Lakes
(2020)Cyanobacterial blooms are considered a major threat to global water security with documented impacts on lake ecosystems and public health. Given that cyanobacteria possess highly adaptive traits that favor them to prevail ... -
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 ...
