Summary:碩士 === 國立臺灣大學 === 土木工程學系研究所 === 86 === In a regional water resources system, water management personnel feels it*s more difficult to set up the reservoir operation policies and distribute water favorably to desired users in the system. Because the shortage of water can*t match by supply and demand problem in time and space. In order to upgrade the water resources environment, and serve as a reference on the water resources management and planning, we always analyze it by mathematical programming algorithm. A linear programming code, MINOS and a network flow programming code, EMNET, were applied to analyze the regional water system optimization. However, the large-scale characteristics prevents linear programming from being applied efficiently to develop the optimal operation policies. Network flow model can properly represent all the essential of a reservoir-river basin water distribution system. In addition, applying the network flow programming model(NFP) to simulate the water distribution has the advantage of light computation burden. The result shows that, depending on the network structure in the model , EMNET is 11-100 times faster than standard linear programming codes, such as MINOS. This model was applied to analyze the transbasin water transport on the Tanshui river basins. Result of the NFP analysis showed an optimal water management process in this system. The release and storage processes of the Shihmen and Feitsui reservoirs demonstrat some interesting characteristics in this system.
