The Migration of the UTHBAL Hydrologic Model into OpenMI

This paper deals with the implementation and the migration into OpenMI of amonthly conceptual hydrological model, called UTHBAL. The model has been developedby Loukas et al. [2003, 2007] and now is implemented under the Microsoft Visual Studio.NET C# IDE. The integrated decision support framework provided consists of anautonomous model engine, a graph editor, an optimization/calibration server and amigration wrapper. The software allows input data polymorphism and extensibility ofmodel integration, which is lumped in the present form. The infrastructure forincorporating various optimization libraries has also been built. On line data exchange isfeasible since the model has been migrated into OpenMI through a dynamicallyconfigurable wrapper. We found that the model characteristics relevant to coupling withother hydrological models lie on the space, time, structure and optimization compatibilities.Thus other models which analyze similar phenomena can seamlessly be coupled with ours.
