## Abstract
Flooding is a problem that causes losses, so efforts to solve flood problems are efforts to minimize losses. To reduce the losses caused as much as possible, there are several approaches to overcome losses through incident management and its impacts. The purpose of this study is to investigate variations in water levels in the Ogan Ilir Watershed in order to monitor fluctuations in water levels to prevent current and future flood problems. This study was conducted by analyzing the flow hydrodynamics in a channel with an area of 256,590 ha using the HEC-RAS program with rainfall data and flow hydraulics data. The results of the analysis showed that there was a very significant change in the inundation area that occurred amounting to an area of 256,490 ha and after the integration simulation between the construction of retention ponds, polders, and the operation of sluice gates simultaneously, there was a reduction in inundation of almost 60% of the watershed area or 153,894 ha.
