| dc.description.abstract | Pedogeomorphology tipology was applied in this research to determine the occurrence of landslide in the
Menoreh Mountains, Kulonprogo District, Yogyakarta Special Region. The research aimed to know (1)
soil characteristics where landslide events occurred in the research area, (2) characteristic of landslide
prone landform in the research area, and (3) typology pedogeomorphic of landslide events in the research
area. Pedogeomorphologic approach was represented through the steps of mapping the occurrence of
landslides and landform, soil profile pedogenitic analysis and geomorphologic analysis at the point of
occurrence of landslide. The results show that landforms characteristic on the occurrence of landslide with
slope 16-75%, elevation 210-807 m dpal, weathered zone depth 25-80 cm, and the position of contacts
on the opposite slope is flat and parallel. The soil characteristics on the occurrences of landslides have a
20-186 cm soil depts with the content 21,50-95,00% of caolinite clay, and clay content ratio between
horion A dan B 0,22-0,91. Pedogeomorphic typology landslides prone classified into 3 levels, namely:
low, moderate, and high level of vulnerability. The low level are indicated by the thickness of soil depth
<70 cm, content of caolinite clay <45%, clay content ratio between horizon A and B > 0,60, slope <
25%, elevation <300 m above sea level, weathered zone depth <40 cm, and the position of the contacts
againts the slope is opposite. The moderate level typically has geomorphic characteristics in between low
and high vulnerability of landslide. Meanwhile high level are characterized by the thickness of soil
depth >120 cm, caolinite clay content >70%, clay content ratio of A and B horizon < 0,40, slope
>60%, elevation >600 m dpal, the depth of weathered zone > 60 cm, and the position of field contact
against the slopes is parallel. | en_US |
