Several field surveys to the project sites are expected to accomplish to understand the present status of watersheds along the banks of Keelung River. Frequency analyses of rainfall in Keelung River Basin are scheduled to finish, rainfall intensity-duration-frequency curves are drawn, and the adequate rainfall pattern can be formed. The adequacy of rainfall network is also investigated by Kriging approach. Furthermore, ARC/INFO analyses of Geographical Information System are applied for analysis the geomorphologic characteristics of river network and watershed topography of Keelung River Basin. Suitable cell structures of every tributary can thus be organized. Semi-spatial distributed with parallel typed reservoirs conceptual model is theoretically derived, model parameters are reasonably optimized, and the resulting flood hydrographs can be simulated for different design conditions. Moreover, the hydrological effects due to urban development along the project areas are analyzed as the functional relationship between the physical parameters and the land-use variation by applying the concept of instantaneous unit hydrograph. Finally, by considering different layout conditions of flood-mitigation plans, the design discharge for the important locations along Keelung River can be modified for the hydrological planning of the pilot area.application/pdf205778 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所降雨分析逕流模擬站網設計都市化演變境況模擬決策支援系統水文規劃Rainfall analysisRunoff simulationNetwork designUrban developmentScenario simulationDecision support systemHydrological planningreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/10757/1/912625Z002009.pdf
