碩士 === 國立臺灣大學 === 生物環境系統工程學系暨研究所 === 90 === The tree-based transportation network plays an important role in water resources management. The effectiveness of the water resource management decisions will be increased if a full network simulation system and spatial database were established with integration of GIS technology and spatial analysis capability. The data structure of USGS/EPA Reach File was referenced in this study of coding the tree-based transportation network for greater efficiency. The concepts of network route and measure in the Dynamic Segmentation were also introduced for more realistic representation in spatial analysis. A portable, easy to maintain spatial data structure was proposed in this study for irrigation canal systems. The Chia-Nan irrigation command area was used as the study region. Issues such as update, query, and related water resource management applications were further discussed. This proposed spatial database framework can be used not only in irrigation canal system for better irrigation infrastructure management, but can also be used for the natural river systems in regional water resources management.
