| 總結: | Pacal reservoirs in Kedungsumber, Temayang, Bojonegoro, Jawa Timur at this time
has been silting significantly. The result of the silting is the reservoir�s water level
continously shrink in recent years. One of the causes of reservoir silting is
sedimentation process in Pacal reservoir. This sedimentation occurs because erosion
processes happened in the Pacal reservoir catchment area so eroded soil material
carried by water stream flowing into the Pacal reservoir.
The usage of remote sensing and GIS (Geographic Information System) are used for
the mapping of erosion using USLE method (Universal Soil Loss Equation). Parameters
used in USLE methods include Rain Erosivity Index, Soil Erodibility Indek, Land
Conservtion (CP), Length and Slope (LS). This research use ALOS satellite censor. This
satelite has three remote-sensing instruments which is Advanced Visible and Near
Infrared Radiometer type 2 (AVNIR-2) for precise land coverage observation.
The final result of this reaserch is the erosion estimation map of Pacal reservoir
catchment area. In the future hopefully this map could support to reduce the erosion
and sedimentation process in Pacal reservoir so that the impacts which follow would
automatically coped |
