The present research analyzes the behavior of Agia Varvara aquifer in Drama, Greece. A comprehensive and complete simulation-management combination model is applied, capable of calculating the water mass balance of the aquifer and defining the optimal management solution. In order to simulate the...

The Plastiras dam was constructed in the late 1950s mainly for electric power production, but it has also partially covered irrigation needs and water supply of the plain of Thessaly. Later, the site has been designated as an environment conservation zone because of ecological and landscape values...

The decrease of available water resources, the water quality degradation as well as the rapid increase of population combined with the growth of human activities, impose today the development of a science that concerns the Management of Water Resources. Lake Volvi faces a lot of problems, the most...

The assessment of the applicability and suitability of potential measures and instruments is crucial in the strategic planning of water resources management. This paper presents a methodology founded on scenario analysis for assessing potentially applicable water management options in a regional...

This paper presents a step-by-step methodological approach for the development and evaluation of strategies for water deficient regions. The primary focus of the approach followed was the mitigation of water stress, while applying the principles of Integrated Water Resources Management and the EU...

Estimation of annual water balance is critical for water management and developmental planning in the area of Anthemountas river basin. In the framework of LIFE04/ENV/GR/000099 project and in continuance to prior projects in the area, the average annual water balance was estimated using the annual...

Groundwater plays an important role for urban and agricultural water supply in northern part of Peloponnesus. Despite increasing environmental awareness in this area, groundwater is a resource that is being stressed. Groundwater provides about 80% the total quantity of water supply. Distribution of...

The Water Framework Directive 2000/60 is a characteristic example of modern European environmental policy, based upon advanced environmental principles. Is reflects a gradual convergence between actual European political consensus on environmental matters and positions of the green movements. Most...

Greece is a typical Southern European country in which the agricultural sector is the major consumer of water, a fact that has potential impacts on the water resources efficient allocation and management. The record-high percentage of the agricultural water use at the national level, together with a...

The European Water Framework Directive 2000/60 has established a new legislation for sustainable management of water resources and protection of their relevant eco-systems. The primary objective of the Directive which is the achievement of acceptable water quality through the implementation of...

The EU directive (2000/60/EC) known as the Water Framework Directive (WFD), identifies new methodology for monitoring and improving of surface water quality in the territory. This includes controlling land-based pollutants as well as defining the constraints for territorial planning. It is...

All stormwater management projects in Greece are required to get environmental permit before construction. The design return period is often determined by the environmental permit. Determination of design discharges is an important parameter for the design. Design discharge for a given return period...

Two Integrated Surface water - Groundwater flow Models (ISGMs) have been developed at the National Technical University of Athens (NTUA), Greece and Cardiff University (CU), UK to investigate surface water-groundwater interactions. The models are based on physical processes and are capable of...

Water movement in the unsaturated zone is an important hydrological process. Richard’s equation is windily used to describe both soil water infiltration and soil water absorption. Various methods have been developed to solve Richard’s equation. Wang et al. (2003) have developed an algebraic model...

Agriculture is an economic activity that contributes significantly to the gross national product of a country, securing at the same time the viability of the rural sector and the social coherence. On the other hand, it can generate an environmental externality, especially concerning water resources...

The two basic forms of multi-scale data assimilation procedures (FDDA), based on Newtonian relaxation, of analysis and observations nudging have been applied for precipitation event period occurred over Portugal during summer season, using the Fifth Generation Mesoscale Model (MM5) developed and...

The subject of this article is the estimation of quantitative (hydrological) and qualitative parameters in the catchment of Ronnea (1800 Km2, located in south western Sweden) through the application of the Soil and Water Assessment Tool (SWAT). SWAT is a river basin model that was developed for the...

A simulation is presented of the operation of brackish karst springs with the MODKARST deterministic mathematical model. Through this simulation, major issues regarding the operation mechanisms as well as the sustainable development of the springs are addressed and analyzed. The particular case...

In order to evaluate how current speed, salinity and water temperature stratification behaves under the influence of a freshwater source in a tidal domain, a 25 hour survey campaign was performed in the upper sector of the Vouga River estuary, the major source of freshwater of Ria de Aveiro, a...
