Water resources estimation, planning and management is an essntial requirement for sustainable growth. The continuous deterioration of the quality of the environment and more specifically the water environment has led to a dramatic change of the quantity, quality and availability of water resources. The situation is becoming more complicated in the view of changes of climate (greenhouse effect) and land use (reduction in forestland, increase in urban areas etc.). In this context, the protection, rational management and exploitation of the water resources are becoming key issues of the strategic planning in a national level.
The project of the National Data Bank of Hydrological & Meteorological Information, which was assigned to N.T.U.A. by the Ministry of Environment, Planning & Public Works, provides the required infrastructure for the implementation of the E.U. Water Framework Directive for the protection, rational management and exploitation of the water resources in the national level.
