The aim of this symposium is to bring together experts from different countries to advance water resource management across the globe, particularly in light of changes affecting water resources. This includes the impacts of climate change, population growth, land use/cover change, changing social perceptions and interests, as well as changes in the policy setting. This will consider both water quantity and quality, and focus on the hydrological aspects, as well as the connections between hydrology and other disciplines (e.g. ecology, agronomy, social science, policy research).
The conference will focus on a range of water resource management methodologies and issues, including:
1. Integrated Water Resource Management: best practices in planning and management
2. Adapting of water resources systems by balancing economic, social and environmental needs and desires (UPH22):
• managing environmental flows to maintain the ecological worth of rivers and receiving bodies (e.g. lakes, wetlands, estuaries, reefs;
• impact assessments of water resources management on public health (incl COVID-19);
• new approaches to assess and control the spatio-temporal distribution of water resources, including advanced sensors and data-driven systems;
• decision making to ensure improved water resource allocation, taking into consideration the breadth of potential users in terms of equity, economy and ecology.
3. Risk-based management of water resources: droughts and the handling of uncertainties in demand and supply model outputs.
Especially invited are contributions with topics related to the “Unsolved Problems in Hydrology” Initiative. Particular questions of interest are here question 22: “What are the synergies and tradeoffs between societal goals related to water management (e.g. water-environment-energy-food-health)?” and question 23: “What is the role of water in migration, urbanisation and the dynamics of human civilisations, and what are the implications for contemporary water management?” During the symposium, a session will be held to specify potential sub-questions of UPH 22 and 23.
Other UPH questions are relevant too, and the authors are encouraged to present their view from the water management perspective:
• UPH 1. Is the hydrological cycle regionally accelerating/decelerating under climate and environmental change, and are there tipping points (irreversible changes)?
• UPH 3. What are the mechanisms by which climate change and water use alter ephemeral rivers and groundwater in (semi-) arid regions?
• UPH 4. What are the impacts of land cover change and soil disturbances on water and energy fluxes at the land surface, and on the resulting groundwater recharge?
• UPH 9. How do flood-rich and drought-rich periods arise, are they changing, and if so why?
• UPH 10. Why are runoff extremes in some catchments more sensitive to land-use/cover and geomorphic change than in others?
• UPH 18. How can we extract information from available data on human and water systems in order to inform the building process of socio-hydrological models and conceptualisations?
