| Zusammenfassung |
| Policy for water resources impacts not only hydrological processes, but the
closely intertwined economic and social processes dependent on them.
Understanding these process interactions across domains is an important step
in establishing effective and sustainable policy. Multidisciplinary
integrated models can provide insight to inform this understanding, though
the extent of software development necessary is often prohibitive,
particularly for small teams of researchers. Thus there is a need for
practical methods for building interdisciplinary integrated models that do
not incur a substantial development effort. In this work we adopt the
strategy of linking individual domain models together to build a
multidisciplinary integrated model. The software development effort is
minimized through the reuse of existing models and existing model-linking
tools without requiring any changes to the model source codes, and linking
these components through the use of the Open Modeling Interface (OpenMI).
This was found to be an effective approach to building an
agricultural-groundwater-economic integrated model for studying the effects
of water policy in irrigated agricultural systems. The construction of the
integrated model provided a means to evaluate the impacts of two alternative
water-use policies aimed at reducing irrigated water use to sustainable
levels in the semi-arid grasslands overlying the Ogallala Aquifer of the
Central US. The results show how both the economic impact in terms of yield
and revenue and the environmental impact in terms of groundwater level vary
spatially throughout the study region for each policy. Accessible integration
strategies are necessary if the practice of interdisciplinary integrated
simulation is to become widely adopted. |
