Model Integration For Assessing Future Hydroclimate Impacts On Water Resources, Agricultural Economic Sustainability And Environmental Quality

The US National Assessment of the Potential Consequences of Climate Variability and Changeprovides compelling arguments for serious consideration of actions and adaptive measures by countries aroundthe world to better manage impacts on water resources, agricultural economic sustainability and environmentalquality. National resource planning at this scale requires integrated impact analysis toolboxes to allow linkageand integration of hydroclimate models, linked surface and groundwater hydrologic models, economic andenvironmental impact models as well as techniques for social impact assessment. The rationale for selection ofthe simulation models is described as well as the challenges faced in linking the component models of theimpacts assessment toolbox. Results from simulations performed with the impacts assessment toolbox arepresented and discussed. After initially attempting model integration with a public domain, GIS-based modelingframework MMS/OUI an interactive, map-based web approach was developed instead owing to the nonconformityof database and model temporal scales.
