Population and Demand ForecastsWater Markets– (change in ownership in perpetuity)
Water Banking– (lease options over some period of time)
Issue: The better the prediction of the spatial and temporal distribution of water, the better the markets can perform.

Integrated Modeling and Decision-Support Systems
•Facilitates multi-disciplinary integration of models and tools to address the issues of water and environmental-resource management.
•Allows rapid evaluation of the effects of decision and management scenarios.
•Allows incorporation of continuing advances in physical, social, and economic sciences.
•Provides an effective means for sharing scientific understanding with stakeholders and decision makers.
SUMMARYSUMMARYToolbox approach to model and system developmentSupports multi-disciplinary model integration for decision support systemsOpen source software design allows many to share resources, expertise, knowledge, and costsFlexible framework approach enables the incorporation of continuing advances in science, databases, and computer technology
