The existing domestic and foreign inundation models usually use the ground elevations as the only input of geographic data, without considering the effect, of buildings in urban areas, on the water movements. Consequently, the simulation results of the traditional models can not completely reflect the physical hydraulic phenomena. The study will integrate the spatial information in urban areas, including the topography, flood-proof and drainage systems, roads and buildings, by using the Geographic Information Systems to establish a GIS-based inundation model for urban areas in three years. The proposed model takes the artificial facilities into account for better reflecting the flood propagation processes in urban areas. The study will also collect the related researches and well-developed inundation models for model comparisons. The theory, numerical method, applicability, limit, functions, and operation interface of these models would be reviewed and compared. The comparison will provide as the reference for the model developing of the follow-up researches. For practical applications, the information techniques will be introduced to improve the user operation and result displaying interfaces for the developed numerical model. The integrated software package of the GIS-based inundation model for urban areas will be supplied to the professional users of water authorities for further researches and applications, and to international academic scholars and experts for cooperation and experience exchanges.application/pdf526700 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所淹水模式都會地區地理資訊系統建物模式比較inundation modelurban areasGeographic Information Systemsbuildingsmodel comparisons行政院國家科學委員會專題研究計畫期中進度報告:地理資訊系統整合之都市地區淹水模式(1/3)reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/10784/1/932211E002024.pdf
