Hydrological modelling of river systems plays an important role in water management. In the past four decades, numerous rainfall-runoff models, river water balance models, groundwater models and hydraulic models have been developed to inform the development and implementation of key water management policies in regulated and unregulated river valleys in different jurisdictions within Australia. In the early years of river system model development, the key focuses were on catchment runoff generation, river flow and water demand modelling of key water users to support development of water sharing plans. In the recent years, there has been greater emphasis on enhancing capability of river system model to represent various consumptive water uses, floodplain take, environmental flow, cultural values, surface and groundwater exchange, water trading, climate risk, etc. to support greater transparency and efficiency in water resources management.
This session aims to bring together researchers, modellers, practitioners and policy makers to discuss the current successes, issues, and potential solutions in dealing with challenges in river system modelling to support water resources planning and management in changing environment in the 21st Century. Contributions are invited in any aspect of river system modelling targeted at servicing modern water management decision making, including:
Key topics: River system modelling, Water resources management, Uncertainty in hydrological modelling, Climate risk
