Abstract

Development of integrated hydrologic models requires coupling of multidisciplinary, independent models and collaboration between different scientific communities. Component-based modeling provides an approach for the integration of models from different disciplines. A key advantage of component-based modeling is that it allows components to be created, tested, reused, extended, and maintained by a large group of model developers and end users. One significant challenge that must be addressed in creating an integrated hydrologic model using a component-based approach is enhancing the interoperability of components between different modeling communities and frameworks. The major goal of this work is to advance the integration of water related model components coming from different disciplines using the information underlying these models. This is achieved through addressing three specific research objectives. The first objective is to investigate the ability of component-based architecture to simulate feedback loops between hydrologic model components that share a boundary condition, and how data is transfered between temporally misaligned model components. The second objective is to promote the interoperability of components across water-related disciplinary boundaries and modeling frameworks by establishing an ontology for components' metadata. The third study objective is to develop a domain-level ontology for defining hydrologic processes.
