This research integrates web geographic information system (GIS) technology and the two-dimensional inundation model (2DIM) to develop an inundation simulation system (ISS). ISS employs the Apache web server, MapServer, HTML (Hyper Text Markup Language), CSS (Cascading Style Sheets), JavaScript, and PHP programming languages to develop online, user interfaces allowing users to input rainfall data directly from their browsers. ISS then simulates inundation and transforms the simulated results into spatial information. The results can be shown on the web using MapServer, web GIS technology. The process of simulation is simplified by running 2DIM automatically instead of manually. Luzhou and Sanchong Districts in New Taipei City are selected in this research to test the ISS during system development and test phases. ISS chooses a single rainfall event for each case to simulate inundation, and transforms the simulated results to spatial information. The simulated results are compared with those simulated manually in a step by step approach, and then ISS displays the simulated results using ArcGIS software. Results show that that ISS is feasible and can be applied to execute 2DIM, and to display geospatial data online. This reduces the complexity of simulation to efficiently reach the objective of real-time simulation.

本研究整合網路地理資訊系統（Web Geographic Information System, Web GIS）展示技術與二維淹水模式（Two Dimensional Inundation Model, 2DIM），研發淹水模擬展示系統（Inundation Simulation System, ISS）。使用Apache網頁伺服器、MapServer網頁地圖伺服器、網頁語言HTML（Hyper Text Markup Language）、CSS（Cascading Style Sheets）、JavaScript和PHP語言開發線上使用者操作介面，可經由網頁瀏覽器加入即時降雨事件資料後直接進行都市地區淹水模擬，將模擬結果轉換為空間資訊展示，簡化二維淹水模式在進行模擬前需要由人工進行複雜的操作流程。研究中選用過去以二維淹水模式進行淹水模擬之案例：新北市蘆洲及三重區降雨事件作為系統開發、測試案例，將ISS線上即時模擬之淹水空間資訊，與過去在單機下操作二維淹水模式搭配地理資訊系統商業軟體（ArcGIS）展示之淹水空間資訊進行結果比較，兩者呈現相同的淹水結果，說明以ISS進行線上模擬並展示淹水資訊之可行性，達到簡化二維淹水模式操作及即時展示淹水空間資訊的目的。
