Is flash flood cycle? A preliminary climate study on Teunom fluvial system

Abstract

The atmospheric dynamics in the Teunom region have caused flashflood several times in last decade, especially in the Krueng Tenom river basin. This problem has been speculated for many scientists who predicted that such flashflood were caused by either regional climate change or the uncontrolled land use in this area. However, it should also be understood the possibility that flash floods may be caused by regional atmospheric cycle. Therefore, this study aims to understand how the climate approach on temperature and rainfall as meteorology process as a way to comprehend whether the flashflood cycle. The result of the research shows that flashflood is actually cyclical, however, due to micro climate change that happened and it is predicted that land use change or land conversion and illegal mining accelerates flashflood cycle so that early warning system is difficult to be implemented.
