The Behaviour of a Turbulent Buoyant Jet into Flowing Environment
(2016)In this study the mean axial velocity at the centreline of a buoyant jet which is discharged vertically upwards from a source, into flowing environment inside a denser ambient fluid (water), in an open channel, is investigated. ... -
Comparing Two Hydro-Economic Approaches for Multi-Objective Agricultural Water Resources Planning
(2020)Hydro-economic models are valuable tools that can be used in irrigated agriculture in order to improve the understanding of the status quo of water resources, the role of water in agriculture, and the system behavior under ... -
Computational Study of the Optimum Gradient Magnetic Field for the Navigation of the Spherical Particles in the Process of Cleaning the Water from Heavy Metals
(2016)The usage of magnetic spherical nanoparticles, coated with substances and driven to targeted areas in tanks, is proposed for cleaning the water from heavy metals. In the present paper, a computational study for the estimation ... -
Determining a Socially Fair Drinking Water Pricing Policy: The Case of Kozani, Greece
(2016)The Water Framework Directive (WFD) 2000/60/EC clearly indicates that all member states should develop and apply water pricing policies to recover the Full Water Cost (FWC) (including the direct cost, the environmental and ... -
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 ... -
The effect of sorptivity on cumulative infiltration
(2021)Hydraulic parameters of the soil play a considerable role in the hydrological cycle, irrigation planning, drainage, groundwater recharge, and water resources management. One of the most important hydraulic parameters of ... -
Estimating the Water Resources Vulnerability Index in the Adriatic Sea Region
(2016)The Adriatic Sea countries face significant problems regarding cross-border water resources management. DRINKADRIA project aims at developing a common methodological framework, for efficient and effective cross border water ... -
Experimental and Numerical Study of Turbulent Flow in Open Channels with Impermeable and Porous Bed
(2016)In order to experimentally and numerically investigate turbulent flow in an open channel with porous (vegetated) and impermeable bed 2D Particle Image Velocimetry (PIV) and a Computational Fluid Dynamical (CFD) model were ... -
Experimental Determination of Hydraulic Conductivity at Unsaturated Soil Column
(2016)Hydraulic Conductivity (K) is an important hydraulic parameter as it affects the environment by controlling infiltration, irrigation rate, and consequently the water movement through the ground. In order to determine ... -
Forming District Metered Areas in a Water Distribution Network Using Genetic Algorithms
(2016)Dividing a water distribution network into District Metered Areas (DMAs) is the first vital step towards water loss management. It is a multivariate problem. Techniques based on Genetic Algorithms is a proven way to provide ... -
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 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 ... -
A methodological framework for an easy and reliable estimation of the full cost of irrigation water
(2020)The requirements of the Water Framework Directive (WFD) 2000/60 for the full water cost recovery have brought reactions and difficulties to their implementation, especially for irrigation water. We propose a systematic and ... -
Policy recommendation for drinking water supply cross-border networking in the Adriatic region
(2017)Cross-border water resources and drinking water supply management are among the basic concerns for almost all Adriatic Sea countries. Adopting measures such as developing common methodologies, tools and techniques addressing ... -
Pressure Management and Energy Recovery Capabilities Using PATs
(2016)Hydro-turbines are widely used in small water energy production plants in order to turn water kinetic energy to electricity. PATs (Pumps working As Turbines) are micro-turbines (small sized compared to the usual ones) ... -
Reducing water shortage crisis through rainwater reuse: Lessons learned from ancient toward integrated technology
(2019)The quantity of freshwater available per person in the world has been proceeded to decrease due to a combination of factors, including population increase, water pollution, inadequate planning and management of transboundary ... -
Similarities and Differences between Hot-film Anemometry and Particle Image Velocimetry in Open Channels
