The International Association of Hydrological Sciences (IAHS), the Universidade do Minho (UM, Portugal), the Laboratório Nacional de Engenharia Civil (LNEC), the Associação Portuguesa dos Recursos Hídricos (APRH), the Associação Portuguesa para Estudos de Saneamento Básico (APESB) have the pleasure to welcome you to The Fourth Inter-Celtic Colloquium on Hydrology and Management of Water Resources, entitled WATER IN CELTIC COUNTRIES: Quantity, Quality and Climate Variability, held at UM, Guimarães, Portugal, July 11-14, 2005.

The Colloquium was organised under the aegis of the International Association of Hydrological Sciences.

The First Inter-Celtic Colloquiumon Hydrology and Management of Water Resources was organised in Rennes, Britanny, France, in July 1996 by the Centre d'Études du Machinisme Agricole du Génie Rural des Eaux et des Forets (CEMAGREF), Direction Regionale de l'Environnement (DIREN), Institut Français de Recherche pour l'Exploitation de la Mer (IFREMER), Institut National de la Recherche Agronomique (INRA), and the Institut National des Sciences Appliquées (INSA). Following the success of the First Colloquium, the Second Inter-Celtic Colloquium "Water in the Celtic World: Managing Resources for the 21 st Century”, was held in Aberystwyth, UK, during July 2000. It was organised by the University of Wales, under the aegis of IAHS and sponsored by the British Hydrological Society. The Third Inter-Celtic Colloquium “Celtic Water in European Framework – Pointing the Way to Quality” was held in Galway, Ireland, during July 2002, organised by the National University of Ireland at Galway, under the aegis of IAHS and supported by the Irish National Committees for IHP, IHHS and ICID, of the National IAHS Committee of the United Kingdom and France and of the British Hydrological Society. Among others the topics addressed were the following: Water quality: pressures and responses; Integrated river basin management; The scientific support for management; Risk assessment, perception and management.

The experience gathered in the previous Inter-Celtic Colloquiums was forwarded to the Fourth Inter-Celtic Colloquium, held in the Northern Portugal city of Guimarães, as the main organisers of previous Colloquiums were invited to join the Fourth Colloquium Organising Committee.

Papers were invited, among others, in the following fields:

Environmental change - climatic change, climatic cycles, land-use development, Global Climate Model, Regional Climate Models and hydrological models. Impact of climate changes to water quality and quantity (surface and groundwater). Uncertainty of climate change and its impacts on the water cycle.

Vulnerability and risk assessment - Surface runoff and groundwater recharge. Floods, droughts and risk management. Groundwater vulnerability, conservation and protection. Risk assessment, perception and management.

Integrated river basin management - Scientific support for management. Water Framework Directive and Groundwater Daughter Directive. Water quality: pressures, responses and aquatic ecosystems. Integrated urban water management under climate change constraints. Public water supply - resources and demand.

Social history of water use in Celtic lands. Paleoclimatic changes and adaptation strategies.


33 papers have been submitted to the Organising Committee for peer review by the Scientific Committee. All papers have been afterward accepted following the introduction of up-grading suggestions made by the reviewers.
