30th IAHR World Congress, Thessaloniki, Greece, 2003 - CD
In about 600 BC, Thales of Miletus, who is considered to be the father of Greek philosophy, stated, water is the basic constituent of everything.Today, in the year 2003, we, as engineers, scientists and citizens recognise the need for protecting and respecting water, this life source and earths most valuable natural resource. The XXXth Congress of IAHR (International Association of Hydraulic Engineering and Research) is to be held for the first time in Greece at the Aristotle University of Thessaloniki (AUTh), August 24-29, 2003, a year that has been officially named by the United Nations as the 'International year of freshwater.'The general theme of the Congress Water Engineering and Research in a Learning Society: Modern Developments and Traditional Concepts was suggested to the IAHR Council by the Local Organising Committee (LOC) with the aim of contributing to the concept of a Learning Society. This may be defined as a knowledge-driven society that invests mainly in the human factor and in education and training. The special theme E of the Congress deals with education and professional developments.Papers submitted for presentation were grouped under the following five themes:

THEME A: Coastal Environment: Processes and Integrated Management

THEME B: Urban and Rural Water Systems for Sustainable Development

THEME C: Inland Waters: Research, Engineering and Management

THEME D: Hydroinformatics and Advanced Data Technology in Engineering Practice

THEME E: Linkage between Education, Research and Professional Development in Water EngineeringThe last theme was achieved through close co-operation between the IAHR Section on Education and Professional Development, UNESCO and the European Thematic Network of Education and Training (ETNET 21) for ENVIRONMENT-WATER sponsored by the EUSOCRATES Programme.Four special seminars (History of Hydraulics, Perspectives of European Water Research beyond the 5th Framework, Transboundary Water Issues, Climatic Changes, Water Resources and Hydraulic Engineering Design), four open discussions 'Agora' (Calibration and Validation of 3D Numerical models, Hydraulic Instrumentation, Water Recycling and Water Technology and the Future) and the John F. Kennedy Student Paper Competition complement the above five themes. The Long Waves Symposium, organised jointly by the IAHR Maritime Hydraulics Section and COPRI runs in parallel to the main Congress. Over 500 papers are presented during the five days of the Congress. The papers (oral and poster) of each theme are grouped in individual volumes, though Theme C takes up two volumes. The volume of Theme D also includes papers from the Agora on Hydraulic Instrumentation: Bridging the gap between users and manufacturers. The volume of Theme E also includes papers from the Specialty Seminar on the History of Hydraulics covering developments in Water Education, Research and Profession from ancient to modern times. A seventh volume is devoted to the 17 papers accepted for the John F. Kennedy Student Paper Competition, while a separate volume includes the papers of the Long Waves Symposium.We hope that the quality of the work presented in these volumes will serve as a useful tool for hydraulic engineers, water scientists and decision makers, when addressing difficult problems in sustainable development of water resources.
