<![CDATA[Based on the land use of the city of Palembang in the Sematang Borang sub-district, there are still catchment areas or swamp areas which are areas that must continue to be considered regarding water resources. The Semang Borang area is currently still in the safe category in the catchment area, but based on the structure of the spatial pattern, the area is in the medium housing category.This study aimed to 1) analyze land use and river network in Sematang Borang District, 2) analyze areas that have the potential to be inundated by tidal floods in Sematang Borang District, 3) analyze the area of land use affected by flood inundation in Sematang Borang District. This study applied survey method and data recapitulation obtained through secondary data from several agencies related to flooding and the River Basin in the Borang River, Sematang Borang District, Palembang City. Based on the results of the analysis of land use maps and river network systems, there are still swamps or open spaces that can be used as water catchments. The magnitude of the potential flood inundation can be observed through a map based on a field inventory with 14 inundation locations. Based on the calculation of rain with a 2-year period of conditions, the river catchment area is still in a safe condition. However, the period 5,10,25,50,100 is in the category of flood hazard. The land area based on the analysis of the area affected by the flood is 845 ha or 8.45 km or 23% of the area of Sematang Borang District of 36.97 km. The factors that affect the height of inundation or flooding in the upstream and downstream areas in terms of land geography, land structure, and drainage system are changes in land use from swamp to medium housing.]]>
