Socio-cultural determinants of water utilisation: Hérault river basin case study (France). Synthesis In the framework of the AQUADAPT European funded project (contract : EVK1-CT- 2001-00104), the work pakage 2 research activities aim at identifying the socio-cultural determinants of water utilisation in four national case studies (France, England, Spain and Slovenia). This report presents the Hérault river basin (France) results where the BRGM realised a survey based on a sample of 400 households representatives of the Hérault river basin population. The questionnaire is composed by about 80 questions that allow to identify behaviours, attitudes and perceptions related to water in general. Results are analyse using basic frequencies analysis, khi2 independence tests, multiple correspondence analyse and agglomerative hierarchical clustering. We then define five water profiles: (i) perception of the water within the environment, (ii) perception of the drinking water, (iii) attitudes face to water pricing, (iv) water saving behaviours and (v) attitudes face to alternative water resources. Based on this five profiles, we attempt to define some households profiles for the whole Hérault river basin, named "national user profile" in the report.
