      It is necessary to analyze the conditions of the watershed hydrometry, the type of land use, the duration and the time of rain, the tidal height, which is modeled spatially, in order to support in decision making for spatial management and water management. Palembang Metropolitan City is one of the major cities on the island of Sumatra, which is regionally included in the Musi Watershed area. Hydrologically Palembang City is located at the mouth of the Musi river, with an altitude of less than 20 m above the mean sea level. When the maximum rainfall occurs in the watershed Area, Palembang City will be affected by tidal water, and runoff on the sub-watershed in Palembang city can not be flowed through the main channel within Palembang City, due to the tide of Musi river water. This study aims to show the relationship between watershed hydrometry, land use change management, rain intensity, and tidal influences on the watershed area, with various scenarios that will affect the runoff discharge and distribution of inundation that occur in the watershed area. Taking a case study of the Lambidaro sub-basin, in the Palembang City area, all sub-basin parameters that have been tested were modeled by a using duflow to calculate the extent of runoff and flood flow tracking in the river. The inundation distribution occurring in the sub watershed was obtained by combining the results of hydrodynamic analysis and spatial analysis. Based on the results obtained it is concluded that there is a strong spatial relationship between land use and sub-basin morphometry and its effect on the extent of surface runoff.
