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 ... -
Applying pressure management to reduce water losses in two greek cities' WDSs: Expectations, problems, results and revisions
(2014)An overall pressure management project applied in two (Kos and Kozani) different water distribution systems in Greece is presented. The two Water Utilities developed a pressure management strategy. In both cases, Watergems ... -
Collaborative migration, coupling and simulation of water resources models through OpenMI
(2010)The present study describes the migration and coupling of a monthly conceptual rainfall runoff model named UTHBAL and a water reservoir operation model called UTHRL into the OpenMI standard. The models have been introduced ... -
Cyanotoxins as the “common suspects” for the Dalmatian pelican (Pelecanus crispus) deaths in a Mediterranean reconstructed reservoir
(2018)Toxic cyanobacterial blooms have been implicated for their negative consequences on many terrestrial and aquatic organisms. Water birds belong to the most common members of the freshwater food chains and are most likely ... -
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 ... -
Developing an Optimization Algorithm to form District Metered Areas in a Water Distribution System
(2016)Exploiting the numerous possibilities that unfold from the inter-connection of Matlab and Epanet software, an algorithm is produced in C++ language. The algorithm reads all the significant data of the water distribution ... -
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 ... -
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 modeling of hydrological processes through openmi and web services
(2011)Difficulty in linking data and models across organizations is one of the barriers to be overcome in developing integrated decision-making systems since not all models exist in the same location. OpenMI is a popular standard ... -
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 ... -
Irrigation of radish (Raphanus sativus L.) with microcystin-enriched water holds low risk for plants and their associated rhizopheric and epiphytic microbiome
(2020)Microcystins (MCs) are toxins produced during cyanobacterial blooms. They reach soil and translocated to plants through irrigation of agricultural land with water from MC-impacted freshwater systems. To date we have good ... -
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 ... -
Root vegetables bioaccumulate microcystins-LR in a developmental stage-dependent manner under realistic exposure scenario: The case of carrot and radish
(2020)Cyanotoxins are secondary metabolites of the ubiquitous cyanobacteria and exert their toxicity to plants and humans. Human health can be impacted by cyanotoxin bioaccumulation in crops via irrigation from contaminated water ... -
Simplified methodology for estimating seismic coefficients for the pseudo-static slope stability analysis of earth dams
(2011)This paper presents a simplified methodology for the estimation of seismic coefficients for pseudo-static slope stability analysis of earth dams and tall embankments. This methodology is based on a statistical analysis of ... -
Simulation and Evaluation of Water Resources Management Scenarios Under Climate Change for Adaptive Management of Coastal Agricultural Watersheds
(2022)The main objective of this paper is to analyze the impact of climate change on water resources management and groundwater quantity and quality in the coastal agricultural Almyros Basin, in Greece. Intensive groundwater ... -
Using Bayesian hierarchical modelling to capture cyanobacteria dynamics in Northern European lakes
(2020)Cyanobacteria blooms in lakes and reservoirs currently threaten water security and affect the ecosystem services provided by these freshwater ecosystems, such as drinking water and recreational use. Climate change is ...
