Abstract
Changes in land use are so fast, has changed the pattern of surface drainage (run-off) in the river sub-system area in urban areas. The problem of stormwater is influenced by several factors, such as occupational problems of riverbanks, improper swamps, river tidal influences, which affect the capacity of river sub-systems in the region[1]. This study will discuss the spatial issues in surface water flow systems in urban spatial planning by emphasizing the integration of run-off and land allocation management. The method used in this study is to conduct spatial analysis using all Run-off parameters in the database structure by utilizing the Land Allocation Management Information System (SIMAL) interface built to test the magnitude of flood peaks using the Nakayasu HSS method, with a case study of the Jakabaring river subsystem , in the city of Palembang. The results obtained were able to see the conversion of swampland, which was utilized for the Palembang Sports City Region in the face of the 2018 Asian Games in Palembang City, has caused flooding in the Kedukan river region, part of the Jakabaring watershed, Seberang Ulu area, Palembang City, Indonesia. Based on the analysis using the Nakayasu unit hydrograph model, the occurrence of peak flooding will occur when rainfall reaches more than 120 mm / hour which causes the low river discharge to reach up to 400m3/sec. Making artificial lakes as a retention pool and at the same time as a sports venue has not been able to reduce the height of the inundation that occurs around 0.6 - 1.2 m above sea level.
