Abstract
The Murray-Darling Basin (MDB) is home to two million people and
accounts for about 60\% of the water use in Australia. The MDB river
system is a highly complex and mostly regulated system covering four
states (Queensland, New South Wales, Victoria and South Australia) and
one territory. Different jurisdictions used different models for water
resources and planning. A number of difficulties were faced in combining
those models (of different characteristics and spatio-temporal
resolutions) for basin-wide water resources planning. In order to
overcome those difficulties and enhance the consistency and transparency
in modelling outcomes across multiple jurisdictions, this paper proposes
a homogeneous agent-based integrated modelling framework. Each agent is
used to represent a region in the MDB. Its behaviour is modelled by a
newly built Source river model. The interactions between agents are
modelled based on the hydrological connectivity in the real-world river
systems. A three-level parallel computing mechanism is developed to
significantly increase its efficiency and reduce computational time. Due
to its homogeneousness, it largely reduces the system complexity and
makes modelling results consistent, explainable and comparable. By
nature, the agent-based system is flexible and portable. All these
unique features of the platform suit the modelling needs of various
states to federal government water resource management agencies.
