Abstract

Retention ponds have the function of temporarily storing water from the drainage system before it flows into the river so that it can reduce flood peaks. In the Palembang area there are 49 retention ponds based on data from the Palembang City PUPR Service, but after investigating it turns out there are 43 retention ponds, this is because there are two retention ponds that have the same name, There are retention ponds that are overgrown with swamp plants so it is difficult to differentiate between retention ponds and swamps, and there is no secondary data that can be used as a reference in looking for retention ponds according to existing data. There are two types of retention pond pavement in the Palembang area, namely concrete pavement and soil with good to damaged structural conditions, while the retention pond doors are functioning well until there are no doors, some retention pond conditions when flooded are not full and will full when the water flow is maximum. From the results of the investigation, the factors causing flooding are the elevation of retention ponds which is lower than residential areas and the buildup of sedimentation in retention ponds, resulting in a reduction in the capacity to hold water flow in retention ponds, so that the maximum discharge in an area that enters the retention pond is not accommodated optimally which causes flooding with the largest flood point having a frequency of more than 15 times a year with a height of more than 50 cm and a receding duration of 3 to 4 hours, and the lowest flood point with a frequency of less than five times a year with a height of 5 to 20 cm and a receding time of 2 to 3 hours.
