In order to demonstrate the capabilities of the OpenMI a complex system of integrated catchment modelling is shown in Figure 1. Meteorological data from a number of measurement stations are handled by a database system. This system will provide precipitation and evaporation data to rainfall-runoff models. The rivers are modelled by a simple conceptual river model that will obtain inflow data from the rainfall-runoff models. For a particular river reach, a more detailed representation of the river flow is required. This river reach is modelled by a physically-based hydrodynamic river model. The river model will obtain inflow data for its upper boundary from the conceptual river model and will provide inflow data for the conceptual river models that connect to the downstream boundary of the hydrodynamic river model. Interaction between groundwater and surface water is considered important at the location of the hydrodynamic model. The underlying aquifer is modelled by a 2D distributed groundwater model. The groundwater model will receive leakage from the river model. The river model will calculate this leakage based on information about the groundwater level, which is obtained from the groundwater model.
