Critical land due to land damage in
watersheds area is mainly caused by the loss of topsoil,
this is driven by the large carrying capacity of surface
runoff flush from rainfall. The Limboto watershed area
is one of the 15 national priority areas because it has a
high level of sedimentation and is vulnerable to natural
disasters. In addition, the area is also classified as
critical land. Information regarding the spatial
distribution and areas vulnerable to land movement is
crucial to preserve the watershed area surrounding the
lake and to mitigate the risks of natural disasters. With
that being said, the purpose of this study is to use the
storie method to analyze the level of vulnerability of
ground movement in the Limboto watershed and its
spatial distribution. Limboto Watershed has 4 level of
ground movement vulnerability from low to very high.
The dominant level of ground movement vulnerability is
moderate with an area of 45.27% of the entire
watershed. Spatial distribution from very high level of
vulnerability is distributed in 3 subdistrict, there are
Limboto Barat, Limboto and Tibawa Subdistrict.
