碩士 === 中原大學 === 土木工程研究所 === 96 === To simplify the complexities in urban water simulations, most of hydrological models only respectively consider subsystems of whole space in urban water environments, for examples, rainfall-runoff model, river flood model, sewer drainage model, etc. Nevertheless, for the real situations, among various subsystems remain physical problems for dynamic physical quantities exchange. Therefore, it is reasonable to render a combination of different hydrological models to approach the realism for the dynamic physical quantity interactions and transmissions. However, from the point view of software engineering, challenges, such as programming languages used for implementing model linking, data exchange formats, and related others, are issued. The purpose of this study is to apply OpenMI framework (interface), developed by EU in recent years, to seamlessly integrate models written by different programming languages, and to seamlessly glue the mismatch of formats arisen from information exchanges. This research is to develop IRES system (Integration of Runoff and Extran System), upon OpenMI framework that provides information exchange with general standards, to integration two SWMM (storm water management model) modules, RUNOFF module for rainfall-runoff simulation and EXTRAN modules for storm sewer simulation, eventually carrying out the real-time storm sewer simulation in urban area. As to verify the reliability of IRES, the practical cases in Taipei City Jhong-Kang, Bao-Yi, Shi-Jeng pumping stations with 24-hour 5-year design storm are selected. Compared with the simulation results from original SWMM, the results obtained by IRES show the excellent agreements. This indicates that the development of IRES can effectively demonstrate physical dynamic exchange mechanisms, to further achieve the purposes of real-time storm sewer simulation. Moreover, during each time step of computing in different models, IRES resolves the issue of the exchange of hydrological data, through the success of the OpenMI framework.
