The Prediction in Ungauged Basins (PUB) initiative of the International Association of Hydrological Sciences (IAHS), launched in 2003 and concluded by the PUB Symposium 2012 held in Delft (23-25 October 2012), set out to shift the scientific culture of hydrology towards improved scientific understanding of hydrological processes, as well as associated uncertainties and the development of models with increasing realism and predictive power. This paper reviews the work that has been done under the six science themes of the PUB Decade and outlines the challenges ahead for the hydrological sciences community.

L’initiative de l’Association internationale des sciences hydrologiques (AISH) sur les prévisions en bassins non jaugés (PUB), lancée en 2003 et conclue en 2012 lors du Symposium tenu à Delft (23–25 Octobre 2012), a été mise en œuvre afin de faire évoluer la culture scientifique de l’hydrologie vers une meilleure compréhension scientifique des processus hydrologiques et des incertitudes associées, et d’élaborer des modèles au réalisme et au potentiel de prévision croissants. Cet article présente une revue du travail réalisé dans le cadre des six thèmes scientifiques de la décennie PUB et souligne les défis qu’il reste à relever par la communauté scientifique hydrologique.
