The study of river stability become fundamental not only to the hydrologists but river
managers as well. The deviation of river from equilibrium state can be interpreted as
the occurrence of severe erosion or sedimentation in the river. The term of hydro is
refer to water while morphologic is appearance through our eye observation. Thus,
hydromorphologic assessment was carried out to test channel stability at Sekayu River
in Kuala Berang. The river index such as Channel Stability Index (CSI), Johnson Index
(1999) and Pfankuch Index (1975) were used to test channel stability at Sekayu River.
It was found that all 11 selected cross sections at Sekayu river show excellent stability
based on the score provided by those indexes. This finding can help authority to make
similar assessment to the other river section of interest and also has its significance
especially to our government that can help to identify mitigation measure for river
restoration process.
