<br />
The master plan of Citanduy River Flow Area Development has been planned since 1976, but it still not applied until today. Since time running and changing in landscape use, the 1976 master plan also experiencing a change. To acknowledge how far the changing, then it will be need a study related to the master plan. <br />
<br />
<br />
Based on the existing condition, Citanduy River Flow Area is most used to fulfill irrigation need, this is appropriate to the area that dominated as farm area. Water for the irrigation need depend on water availability in upper course, and it cause less water in lower course area. To solve the problem, master plan 1976 planned to build eight reservoir includes Pasirangin reservoir, Manonjaya, Banjar, Ciamis on Citanduy River Binangun 1 and 2; Cikembang on Ciseel River, and Matenggeng on Cyolang River. <br />
<br />
<br />
If there are reservoirs build addition based on the planned years, the master plan also cover water flow simulation using Water Resources Management Model (WRMM), in this study the addition are five more reservoirs that located in Pasirangin build in 2010, located in Manonjaya build in 2015, located in Banjar build in 2020, Cyolang and Cisaat Sub River Flow Area build in 2030. <br />
<br />
<br />
Based on the simulation one more additional reservoir must be build, since it will result 20% debt raising for service and 30% for time. If three more reservoirs build then it will happen 30% debt raising and 40% time raising; if five more reservoir add, the service will be 35% debt raising and 50% for time, thus, the service will improve between 80% and 100%. <br />
<br />
<br />
Based on the next simulation there is optimalization effort using rule curve until gained reservoir time operational appropriate to debt volume. <br />
