GROUNDWATER POTENTIAL OF THE ISLAND OF CRETE. PROBLEMS AND PERSPECTIVES.

This paper presents, reviews and evaluates the latest views and researches carried out on groundwater resources potential of the island of Crete. Data on the overall water budget of the island are provided, whilst information is also furnished on the actual water demands and the current percentage these are met. Comments and proposals are made towards further rational management of the documented rich groundwater potential of the island along with proposals on the utilization of the considerable surface runoff waters in the form of off-course basins and dams. The distinctiveness of the Water District of Crete, in comparison with the rest Districts of Greece, lays on the fact that it is the only one for which an Integrated Water Resources Management study exists that was compiled in the period 2000-2001. Elaboration of this study was assigned by the Regional Authority of Crete, Directorate for Planning and Development, Section of Water Resources Management, to the consorting consultancy firms of PAPAGRIGORIOU S., KAIMAKI S, PARLEROS V., PAPAGEORGIOU N, LAZARIDES and Ass., ATEM, with special scientific consultation from the firms ENVECO S.A. and WL/DELFT HYDRAULICS of Netherlands, on December 1999 following an international procurement.

Water Uses

<p>Traditionally, the use of stochastic models within water resources management aim to provide synthetically-generated inflow time series that reproduce the statistical regime of the historical data. On the other hand, the water uses are typically handled as steady-state elements, which follow a constant seasonal pattern over the entire simulation horizon. However, given that the demands are associated with highly uncertain hydroclimatic and socioeconomic factors, they should also be considered as random variables, as made for inflows. Using as example a complex hydrosystem in Western Thessaly, Greece, comprising both surface and groundwater resources to serve irrigation, water supply, environmental and hydroelectric uses, we demonstrate the advantages of a fully stochastic setting of the water management problem over its traditional configuration. Among others, we investigate the use of synthetic demands that are correlated with inflows, given that both are driven by hydroclimatic processes. Data syntheses are employed with the recently introduced AnySim stochastic simulation package (https://www.itia.ntua.gr/en/softinfo/33/).</p>

Smart Water

Water resources management requires the integration of many complex physical processes, as well as the interaction of many stakeholders, to ensure the sustainable use of surface and groundwater resources. Water problems to which water authorities have to face are water deficit to supply a wide and increasing demand, floods, water pollution, leaks in water distribution infrastructures, and optimization in the energy use and production. A comprehensive and detailed analysis of the availability of water resources in terms of quantity and quality, and of water demand in their variability in space and time, is indispensable. In this context, SAID (SmArt water management with Integrated Decision support systems) project addresses the development, implementation, validation and integration of the most innovative DSSs as the basis for smart water management systems in complex basins. This paper focuses on the methodology carried out to integrate multipurpose aspects involved in the management of water resources in Guadalhorce River Basin (southern Spain), as a demonstrator area. As a support in the decision making process to dam managers, the resulting integrated DSS allows to execute predictive simulations to anticipate the watershed response, considering two types of scenarios (flood and ordinary), driven by different optimization criteria.

Resources Management

Abstract The water resources management in the developing countries calls for the adoption of the systems approach in accordance with the regulations of the Kyoto Protocol (1997) clean development mechanism. In this research, integrated modeling was carried out under multipurpose scenarios using six reservoir dams with a capacity of 10,500 MW (megawatt) to reduce the greenhouse gas productions. The simulation and development of the integrated water evaluation and planning (WEAP) model within a 50-year period, along with the development of the MODFLOW model in alluvial deposits that interacts with the river, allowed for the analysis of the integrated water resources management system of the Great Karun basin. Several scenarios were implemented following the calibration and validation of the linked integrated model. The components covered by these scenarios included the satisfaction of the in-basin and off-basin demands, the effect of the integrated consumption of water resources, and the effect of increased efficiency of irrigation networks with maximum clean hydroelectricity production and minimum aquifer level decline under drought-induced water shortage conditions. The second scenario, which generates 15,282 GWh (gigawatt-hour) of power, not only optimally meets the future and environmental demands as the best operating scenario but also minimizes the emission of the greenhouse gases in the basin.

Development Objectives

This effort discusses and evaluates alternative water management options to alleviate water stress and meet water needs in insular entities of the Aegean Archipelago, within the framework set by the principles of Integrated Water Resources Management (IWRM) and of the Water Framework Directive 2000/60/EC. Options are presented and assessed to determine integrated applicable strategies reflecting technical, economic, social and environmental constraints. The assessment is based on the application of the WaterStrategyMan Decision Support System (WSM DSS), developed under the Fifth Framework Programme, and is performed for six islands of the region. Results emphasize the need to understand the interconnections between social, technical, economic, and environmental problems in order to reach integrated solutions. In the dynamic context of current societies, pragmatic policy initiatives are needed to improve the means of preventing and addressing such issues, as well as new institutional structures to handle appropriately competing and conflicting water demands and development objectives.
