The 2014 flood that happened from December 2014 to January 2015 is considered to
be the worst flood in a decade. In this study, the application of the ROSE Index has
been used to predict the probable risk month for Kuala Terengganu and Hulu Besut
area. The application of the ROSE Index emulates the use of rainfall intensity, rainfall
energy rainfall erosivity at characterizing the risk level. The category of low, moderate,
high, very high and critical risks are classified to develop an eventual risk calendar
throughout the year. It was found that month of December is a critical time for these
two districts and the second week is susceptible to receive high amount of rainfall
event. The rainfall erosivity exceeding the normal national range and proven to be one
of the main causes for major flood disaster on 2014.
