Abstract
Gajah Mungkur reservoir is a multipurpose reservoir with broadness of 8.800 ha. Its functions for irrigation, hydroelectric power, source of drinking water, tourism, aquaculture and Presently the sustainability of reservoir function is distressed by emerging of wrinmnation. The sedimentation may be reduced water volume, create siltation, decrease cariying capacity, create rust and corrosion on the turbine engine. The aims of the research is to observe the sedimentation rate at Gajah Mungkur reservoir as a base line study on the reservoir management model. The research has been counducted at Gajah Mungkur Reservoir, Camel of Jawa during the period of February to Desember 2011. In order to estimate bathymetry of this reservoir the acoustic survey methods has been applied whitest the sit traps is applied to estimate the sedimentation rate. The results of this research showed that maximum depth was 16 m, average depth was 6.07 m, average water volume was 408.512.270 m3. Compared to the situation when the reservoir was built in 1981/1982 the average depth was 9 m, average water volume was 630,000,000 m3- It is mean that after 28 years there is a reduction of water volume about 201,088,000 m3 and reduction of water depth 2.93 m. The sedimentation rate was higher during the rainy season i.e. 2,76 m3I hal day, The average sedimentation rate in one year was 6 cm/year, 593.71 m3/ha/year, 822.53 tons/ha/ year.
