Abstract

![CDATA[Remote Sensing (RS) and Geographic Information System (GJS) methods can be employed for identifying and mapping landslides for quick and effective results avoiding time consuming physical studies. Currently, landslide identification mainly covers large scale mountainous landslides, while small scale shallow landslides in relatively plain lands are still overlooked. The processes and techniques involved in such studies are also developed based on large scale landslides. This necessitates carrying out similar studies based on small scale shallow landslides. This study focuses on rainfall induced shallow landslides that occurred in Cox's Bazar district of Bangladesh during 14- 15 June 2010. The study adapts common techniques and methods involved in landside studies and apply them to small scale landslides. The identification was conducted using 2D visualization of high-resolution image and semi-automatic recognition of medium resolution images. A novel method of integrating manual interpretation and semi-automatic results was used to obtain a final landslide inventory. The validation of the model was conducted using actual landslide events of June 2010 where validation results revealed a high degree of landslide prediction represented by success rate curve and associated Area Under Curve (AUC) value of 0.8913. The validity of predictive model prove the efficiency of the method and justify their use for rainfall induced shallow landslides.]]
