Effects of global warming on landslide frequencies in Ratnapura District, Sri Lanka - 2011

Abstract

Unpredictable variability of rainfall patterns could probably be due to global climate changes with the increased frequency of extream whether events. Infact, rainfall is the most relevant factor for the triggering of both shallow and deep - seated landslides in Sri Lanka. Landslides related to heavy rainfall cause widespread property damage and occasional loss of lives. in recent years, number of rain-induced landslides have been increased in the Ratnapura district due to heavy rainfall. One of the most critical concerns in landslide study at the moment is the potential link between climate change and the frequancis of mass movement occurrences. In this research and overall study of the climate change on landslide frequencies in Ratnapura, distric is done by analysis the trend of the rainfall and temperature variation patterns.
