Abstract The dynamic integration and management of models are key demands in the construction of the hydro-modeling platform (HydroMP). The corresponding key technologies include a driving model for the platform, data exchange between the model and the platform, real-time control of the model operation and dynamic management of the models. General model integration methods supporting hot-plug modules are used to integrate different types of models into the HydroMP and to meet the needs of different users. An EXE integration method is developed that does not require changes in the existing running mode of the model programs. There is no need to rewrite the original code to realize the model integration using the EXE integration method; only data conversion modules are needed. An interactive integration method is developed that gives real-time communication between model processes and the platform. This interactive integration approach uses a standard communication program to encapsulate the model and generate a new model program. Then, the new model is registered in the platform to realize the model integration and management. The interactive integrated model process provides real-time communication and data exchange with the cloud platform. These two integration methods are applied to the HydroMP to provide dynamic integration and management of different heritage models.
