Floods in Malaysia

Floods in Malaysia are one of the most regular natural disasters affecting the country, which occurs nearly every year especially during the monsoon season. The coasts of peninsular Malaysia are the most prone to flooding especially during the northeast monsoon season from October to March.[1]

Gombak river merges with the Klang river. Heavy development has narrowed certain stretches of the river: this contributes to flash floods in Kuala Lumpur, especially after heavy rain.

Causes

edit
  • Given Malaysia's geographical location, most floods that occur are a natural result of cyclical monsoons during the local tropical wet season that are characterised by heavy and regular rainfall from roughly October to March.
  • Inadequate drainage in many urban areas also enhance the effects of heavy rain, though efforts are underway to resolve this.[6]
  • Climate change in Malaysia is expected to impact flooding in the country, with the frequency of extreme weather increasing.[7]
