DRIHM is a European infrastructure project funded by the EC to provide a platform for hydro-meteorological research. It aims to integrate meteorological, hydrological, and hydraulic models from various sources into a unified interface. Behind this interface is a distributed computing infrastructure that runs experiments using the different models in deterministic and probabilistic modes. This allows scientists to perform multiple experiments simultaneously and analyze the results.
