The Study on Interoperation of Hydrologic Models and its Application

As global water systems become increasingly complex and the urgency of sustainable water management intensifies, hydrological models are evolving toward modular and interoperable architectures. This study investigates the interoperability mechanism of hydrological models and proposes a framework for developing standardized, plug-andplay modules. The approach combines modular decomposition, semantic metadata, and GIS integration, enhancing model reusability across diverse simulation scenarios. A detailed case study demonstrates the practical applicability and effectiveness of this framework.
