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 Change provides compelling arguments for serious consideration of actions and adaptive measures by countries around the world to better manage impacts on water resources, agricultural economic sustainability and environmental quality. National resource planning at this scale requires integrated impact analysis toolboxes to allow linkage and integration of hydroclimate models, linked surface and groundwater hydrologic models, economic and environmental impact models as well as techniques for social impact assessment. The rationale for selection of the simulation models is described as well as the challenges faced in linking the component models of the impacts assessment toolbox. Results from simulations performed with the impacts assessment toolbox are presented and discussed. After initially attempting model integration with a public domain, GIS-based modeling framework MMS/OUI an interactive, map-based web approach was developed instead owing to the nonconformity of database and model temporal scales.
