2. Background
• Jatiluhur reservoir is the one of the most important
reservoir which located in West Java Indonesia.
• Working at Weather Modification Technical Unit as
Hidrologist
• Data Pattern on Inflow to the Reservoir, Rainfall
analysis, and Water Level at Reservoir.
• Recent years, there have been two big floods at
Jatiluhur downstream catchment area especially in
Karawang at 2010 and 2013. At the last event, the
flooding caused by the high water level in Jatiluhur
reservoir that exceeds the threshold water level
