Abstract


The research area is located in the Baluburlimbangan, Garut regency, West Java Province.
Geographically, the research area is located at 107° 52' 23.32" E - 107° 59' 30.04" E and 6° 57
'28.21" S - 7° 3' 39.23" S. Research object comprise Cianten and Cisaat watershed which will be
compared based on morphometric and morphotectonic parameters. Observations carried out
directly in the field and data analysis carried out in the studio. Research result shows that research
area can be classified into medium – weak active tectonic area. It is proved by bifurcation ratio
(Rb), drainage density (Dd), and sinuosity of mountain front (Smf). Active tectonic condition is also
indicated by geology structure formed in research area such lineament of ridge and valley, and
drainage pattern.
Keywords: Cianten, Cisaat, morphometry, morphotectonic, watershed
