ABSTRACT
This study proposes water body detection using remote sensing techniques and monitoring the changes in water body due to urbanization. The monitoring timeline from 2013 until 2019, with acquisition of different satellite imagery dataset for both years. Project area of this study is Johor River in the region of Pulai, Johor. Satellite imageries used in this project are Landsat 8 acquired in 2013 and Sentinel-2 from 2019. There are two aspects in this project, to detect the presence of water body in project area using remote sensing technique and to monitor the changes of Johor River in Pulai region in 2013-2019. For detecting presence of water, multispectral bands combination and Normalized Difference Water Index techniques were used, mainly to distinguish water body and non-water body features. For river changes monitoring, image classification method was used to monitor the changes in those years.
