The Use of Correspondence Analysis on the Visualization of Locality and Seasonal Behaviour on the Flood Pattern in Malaysia
Keywords:flood pattern, flood visualization, correspondence analysis, locality and seasonal behavior
Flood mitigation and assessments are crucial in current time. The seasonal and nonseasonal of flood occurrence in Malaysia provide risk towards country growth and productivity. In this study, the flood pattern will be analysed by using correspondence analysis. The data involve the occurrence of flood based on month and locality from 2013 to 2018. The test of independence (?2 test) between month and locality indicated independency among the variables (p=0.615). The symmetric plot suggested that Perak, Melaka, Selangor, Johor, Terengganu, Sarawak inclined to have flood occurrence during December to March, while Kedah and Penang during March. This analysis will help authorities to better planning flood mitigation accordingly.
