Shihmen Reservoir has contributed to the economic development of northern Taiwan since it was built in 1964. As result of natural disasters and improper development, Shihmen Reservoir had a big problem with sediment deposition. To solve this problem, government executed the first stage of integrated treatments planning on Shihmen Reservoir.The period of program is from 2006 to 2008 and divided into three parts. From the government point of view, this study recognized the use of agriculture water¡Nindustrial water¡Ndomestic water¡Nelectricity generation¡Ntourism and decreased sediment extraction expense as benefit index ¡F recognized budgets and natural disasters as cost index to evaluate the effect of this program.The value of benefit-cost ratio before integrated treatments is 2.817 and the value of benefit-cost ratio after integrated treatments is 3.566. The value of benefit-cost ratio after integrated treatments is bigger than the value of benefit-cost ratio before integrated treatments.It means that it is workable for this program. Considering the reason that the water rate and utility bills are much cheaper in Taiwan, this study adjust the rate of water and utility individually. With the adjustment of water rate, the value of benefit-cost ratio before integrated treatments is 3.519 and the value of benefit-cost ratio after integrated treatments is 4.31. With the adjustment of utility rate, the value of benefit-cost ratio before integrated treatments is 3.689 and the value of benefit-cost ratio after integrated treatments is 4.074. It is also beneficial for this program.
