Abstract

Integrated modelling is an established procedure for the linking together of separate numerical models in a dynamic interactive manner. The models linked together (called a composition) are able to exchange data with each other on a timestep-by-timestep basis and allow feedback from interacting processes to update the calculation processes as they are carried out. This enables complex hydraulic and environmental situations to be more accurately simulated. The paper describes FluidEarth; a community initiative that enables UK academics to gain access to suitably prepared (wrapped) software components and develop integrated model compositions using these components. The paper then continues by presenting an example of integrated modelling using FluidEarth tools. The example features how a model simulating building collapse can interact with a hydraulic model of the floods around it that cause its structure to fail. FluidEarth has a web portal accessible at https:\\www.fluidearth.net. This portal provides a range of tools and guidance to support integrated modelling as well as repositories of wrapped and non-wrapped software components. Further work is planned in the near future to provide procedures and data for calibration and validation of software components and model compositions. FluidEarth is able to provide a platform for compositions to be deployed and executed, whilst linked to the forcing data required to drive them. The aspiration is for FluidEarth to provide the UK node to a network of joined up computerised systems working in the water and environment sector. FluidEarth was a medallist in the British Computer Society Annual Industry Awards in 2009 for research and innovation.
