中文摘要 | 近年來由於GIS技術的進步,讓水文模式進行空間與時間之模擬與展現上更完善。其中又以美國佛羅里達大學所發展的SWBM模式最具未來性。此模式完全架構於國內最常使用之地理資訊系統程式Arc View中,模擬結果可直接以圖層進行展示與運用。 本研究首先詳盡介紹SWBM模式的概念以及功能,最後以臺大實驗林溪頭營林區所轄擁有流量觀測之小集水區為試驗區進行逕流量模擬。結果顯示,逕流量模擬結果可反應實際變化趨勢,相關係數為0.9,然而由於SWBM無法有效模擬伏流水,暴雨下模擬之逕流量有偏高情形。 |
英文摘要 | Hydrological models were developed to simulate and exhibit more powerful because of the improvements of GIS techniques. Spatial Water Budget Model (SWBM) was one of the most useful models which was developed by the Crop Modeling Systems Laboratory of the University of Florida. SWBM was built upon GIS base software ArcView. Therefore, the simulated result could be showed and advanced analyzed easily. The purpose of this paper explained the concepts and functions of SWBM at first, and then used SWBM to simulate daily hydrological temporal and spatial distribution within experimental site (a small watershed with runoff measuring in Chito District of The Experimental Forest of National Taiwan University). The correlation between the simulated and measured runoff pattern was 0.9. Then, the result of runoff simulation was over estimated because SWBM could not simulate subsurface flow very well. |
