In the last decades, Palembang City has faced a serious problem related to urban drainage system and flooding. This problem requires a systematic solution especially on how to solve the flood problems. Land use change is apparently one of the most important factors that result in higher run-off while another factor concerns the operation and maintenance of the urban drainage systems in Palembang City which has to be improved properly. This research focused on land use change and land utility management. In this research, the river sub-system of Palembang City was taken as the research unit. This was in order to evaluate the structural conditions in an urban area by applying the land unit concept and using the landscape ecology approach. Because of that, the morphometric characteristics of a sub-river system had to be identified as input to the scenarios related to the hydraulic model, so as to map the runoff, inundation, water level in the drainage system included geospatial analysis in a sub-river system. The ultimate goal of this research was to develop a model for management of a river sub-system which can be used for the early warning system in relation to the constructing permission (land use change) in the river sub-system area. This model integrates a geographical information system technique with urban drainage management and flood protection systems. The above-mentioned research approach was applied in the case study of Bendung sub-river system in Palembang City. It is proved that the integration between landscape ecology, urban drainage hydraulic and geographical information system is a useful tool and approach which can be used to evaluate the effect of any land use change on urban drainage system and its hydraulic performance in lowland areas. To validate the model, a calibration on the inundation map with the field conditions is recommended.
