The biennial Water Resources Management conference is one of the most important of several water-related conferences organised by the Wessex Institute of Technology.As water becomes an increasingly precious resource, communities all over the world Are under extreme pressure to ensure its continued adequate supply to their populations. It is therefore essential that those responsible for managing water resources share their expertise in dealing with issues of water quality, quantity, management and planning, as well as other related concerns that help or hinder sustainable management of this vital resource. In this volume, containing research on recent technological and scientific developments associated with the management of surface and sub-surface water presented at the Sixth International Conference on Water Resources Management, they do just that. The research covers: Water management and planning; Waste water treatment, management, and re-use; Markets, policies and contracts; The right to water; Urban water management; Water quality; Pollution control; Irrigation problems; River basin management; Hydraulic engineering and Hydrological modelling; Flood risk; Decision support systems; Remediation and renaturalisation; Climate change and water resources; Governance and monitoring; Regional and geo-politics of water; Economics; Water ecology; Sanitation; Wetlands; and Extreme events.
