Floods are the most widespread natural hazard in the Peninsular Malaysia. Massive
loss of properties and unaccountable damaged due to the occurrence of the worst
flood in 2014 made the nation aware of this tragedy. Thus far, there is no risk calendar
ever produced in east coast of Peninsular to assess flood occurrence. The risk calendar
was created by looking at the extreme cumulative rainfall in a span of a day. In
addition, the degree of rainfall erosivity was determined to assess the level of rainfall
energy. Gua Musang and Kuala Krai districts are the two case-study to create risk
calendar. The rainfall data were obtained from Department of Irrigation and Drainage
(DID) station commencing from year 2010 to 2016. It was found that second weeks
of Month of December is critical time for flood occurrence and the duration of three
days is a threshold of greater flood events.
