摘要

現有的都市水文模式，大多將都市水文問題切割成許多子系統（例如降雨、地表逕流、地表淹水、雨水下水道水理等）分別模擬以簡化問題之複雜性。但真實情況中，各子系統間存在著動態物理量交換問題。因此，結合兩種水文模式較能夠表現出水文子系統間的動態物理量之交互傳輸。然而，由軟體工程的角度來看，模式的連結方面存在如模式撰寫所使用之程式語言、資料交換的格式等問題。
本研究的主要目的為應用歐盟近年來開發之OpenMI架構(介面)，以解決不同模式撰寫之程式語言不同與模式間資料交換格式的問題。研究中研發一IRES系統(Integration of Runoff and Extran System)，以OpenMI架構提供之資料交換標準規格整合SWMM（storm water management model）模式之RUNOFF模式（降雨逕流模擬）與EXTRAN模式（雨水下水道水理模擬），以進行雨水下水道即時水理模擬。為驗證IRES系統之可靠性，比較IRES系統與原始SWMM對台北市的中港、保儀、實踐抽水站系統之五年24小時設計雨型模擬結果，其模擬結果比對相當一致。由此顯示，本研究所研發之IRES系統能有效表現出物理量動態交換機制，達到即時模擬之目的，且IRES系統在每一個時段進行的演算工作中，透過OpenMI架構成功的解決了水文資料交換問題。

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.
