Water availability, excess and scarcity

Operation management of water resources

Sustainable development and management of water resources in the river basins of the world is essential to healthy ecosystems and contributes to socio-economic development, risk mitigation and poverty reduction. The Sustainable Development Goals, in particular goal 6, underline the importance of dealing with the increasing pressures on water resources. This calls for a concerted effort to improve water security; providing safe access to water for food production, sanitation and health; at an acceptable level of risk in the face of natural hazards such as drought and floods

Our research focusses on developing the scientific evidence base to underpin both river basin management planning and the operational management of water resources. Research topics include efficient and balanced allocation of surface and groundwater water resources to support key functions, including hydropower and energy; irrigation; domestic and industrial water supply; the environment, and others. Linking scientific knowledge on hydrological and hydraulic processes, understanding feedback loops with society, and the value of information in developing integrated and transparent river basin management planning; as well as flood and drought management planning are key concepts in our work.

Managing hydrological extremes: Droughts and Floods

The intensification of the world’s climate is leading to increased occurrence of droughts and floods. As a consequence of global socio-economic changes, the impact of these extreme events on society are increasing. Equally there are feedbacks between society and the occurrence of impacting events. Our research explores how these events can be characterised using appropriate indicators, and such events can be forecasted. Key research questions we address include how data and information can be used to inform decisions and the implementation of measures that can help mitigate impacts, and the role of uncertainty and communication.
