Abstract
The Wonogiri Reservoir capacity decreases rapidly, caused by serious sedimentation problems. In 2007, JICA was proposed a sediment storage reservoir with a new spillway for the purpose of sediment flushing / sluicing from The Keduang River. Due to the change of reservoir storage and change of reservoir system, it requires a sustainable reservoir operation technique. This technique is aimed to minimize the deviation between the input and output of sediments. The main objective of this study is to explore the optimal Wonogiri reservoir operation by minimizing the sediment trap. The CSUDP incremental dynamic programming procedure is used for the model optimization. This new operating rules will also simulate a five years operation period, to show the effect of the implemented techniques. The result of the study are the newly developed reservoir operation system has many advantages when compared to the actual operation system and the disadvantage of this developed system is that the use is mainly designed for a wet hydrologic year, since its performance for the water supply is lower than the actual reservoir operations.

IntroductionThe evaluations of the storage-yield and the operational performance of a reservoir form an important part in the study of water resources development
The evaluation is an important part in the study of water resources development (Tu et al 2003, Tu et al 2008, Srivastava, 2009 and Wulandari et al 2012)
The optimization is performed by the Incremental Dynamic Programming technique using the CSUDP program package
Summary
The evaluations of the storage-yield and the operational performance of a reservoir form an important part in the study of water resources development. Application of the mode, ling for reservoir system analysis involves studies especially to reevaluate storage-yield and operation performance for existing reservoir systems. Such periodic evaluation may be required to assess the responsiveness of a system to prevailing conditions and demands arising control reservoir sedimentation have done by some researchers, as follows Nicklow & Mays (2000), Chang et al (2003), Ji (2006) and Hadihardaja (2009). The research show due to sedimentation problems in reservoir, it becomes necessary to develop reservoir operation for control sediment and the operation produce the performance of good
