Abstract. The MEDIGRID project aims to use distributed GRID tech-nology to integrate natural hazard models, maintained independently at different centres in Europe, into a single system, accessible to users over the internet. As an example, the SHETRAN hydrology, soil erosion and landslide model can receive input from a separate fire propagation model and in turn can provide data to a vegetation regeneration model. The individual models are located at process nodes while data relevant to for-est fire impact modelling are provided at data storage nodes. Each node has been fitted with the Globus Toolkit, which provides the shared, spe-cific computing environment required for the system construction. Users access the system through a series of portals and portlets, which provide a personalised interface to the Grid. Integration of the individual models required them to be modified so as to be run remotely over the inter-net as web services. As the models have different data characteristics, a common data format was created to allow exchange of data between the models. The MEDIGRID system marks an advance in the integra-tion of independently constructed models to provide improved hazard assessment technology.
