Abstract :
The gross reservoir capacity of Selorejo
Reservoir in 2019 has decreased to 29.73 million m3
, or
47.72% of the planned gross reservoir capacity due to
sedimentation. Decreased reservoir capacity leads to
reduced water allocation for energy generation (PLTA),
fulfillment of irrigation in the dry season and ability to
control floods in the rainy season. The analysis of the
potential for land erosion used in this study is using the
USLE (Universal Soil Loss Equation) method.
Sedimentation management strategy in Selorejo
Reservoir is by structuring the catchment area and
managing sediment in the reservoir in a sustainable
manner. The sedimentation potential that occurs in
Selorejo Reservoir catchment area is 609,328.60 m3
/year.
The structuring strategy implemented in the catchment
area to support the sustainability of the function of
Selorejo Reservoir is expected to reduce the potential of
sediment by 580,000 m3 by planning sediment control
buildings, critical land rehabilitation, and sediment
dredging at TokolSabo Dam. The sediment management
strategy applied in selorejo reservoirs to support the
sustainability of reservoir function is to dredge sediment
by 200,000 m3
/year, and the need for good management
related to dredging activities, spoilbank preparation,
hauling and utilization of sediment material.
