The impacts of changes in land use from green open spaces to developed areas will affect the ability of soil water absorption, and the quality of water along the watersheds causing flooding. Palembang city has 22 points of road segment and 43 points of flood prone areas including in Buah watershed. Buah Watershed is prone to the flooding and included as critical watersheds in the city of Palembang. The cause of flooding in the watershed because of the conversion of green open space space into residential areas as well as developed areas.

Along with the increasing number of residents in the city of Palembang and the development of economic levels of urban communities will trigger land utilization. The excessive of land utilization affects the city of Palembang into a flood-prone area due to the reduced absorption area as green open space. Increase of flood prone in Buah watershed are caused by various factors ranging from degraded trash sedimentation, inadequate drainage canal capacity and poor condition of canal drainage, as well as conversion of protection swamps into reclaimed area.

This study aims to determine how significant the effect of changes in land use patterns from 2000-2017 that can affect flooding in Buah watershed in Palembang City. Method applied is descriptive quantitative by using overlay analysis and supported by field observation, documentation, and interview to know the distribution of flood location at Buah watershed from land use change point of view.

The result of overlay analysis shows that land use change from open space into residential in Buah watershed for 17 years is 25,74%. Flood location in Buah watershed in 2012 was 34 location points and increased in 2017 into 38 points flooded locations with higher intensity.
