How can hydrologists contribute most effectively to the planning and management of freshwater projects, including the efficient operation of existing systems faced with new socio-political situations? And how can water resource managers capitalise on the hydrological expertise available to them? The contributions discuss these topics and consider the need to include more environmental, social and economic aspects in the planning and management of projects, while keeping in mind the sustainability of water resource systems: Integrated Water Resources Management; Hydrology and Dams; Hydrology for Flood Protection; Hydrology and Water Supply Systems; Hydrology for Groundwater Management; and Hydrology for the Protection of EcosystemsThe International Association of Hydrological Sciences is the world's premier member-based organization promoting the study and practice of Hydrology.
