Using the OpenMI standard for developing integrated systems of hydrological modeling

Demonstrated is the experience of developing a model of the integrated system of hydrological modeling based on the use of the operational data of the Roshydromet automated observational network and of the prognostic data of weather models. The system is based on the Open Modeling Interface (OpenMI). The major blocks of the system are data sources, hydrometeorological models, and spatial data on the catchment needed for predicting the river runoff formation process in the real-time mode. To construct the components of the data support, modern standards and techniques in the area of hydrology are used. It is demonstrated that this approach is a promising technical solution and opens up good possibilities for obtaining new scientific results.
