Way Ruhu River is one of the watersheds in Sirimau District, Ambon City. The limited handling of the city government and the awareness of the local community to expand residential areas in the Way Ruhu watershed resulted in floods and landslides that brought sedimentation and garbage, this caused shallowness that occurred on the riverbed, thereby overflowing river water into the residential area of Hative Kecil, Galala. and Aster. To overcome this problem, an intensive study and periodic handling of sedimentation and garbage on the riverbed is required by periodically backfilling the Way Ruhu river area. Therefore, the analysis of sedimentation and garbage in the Way Ruhu river needs special handlers to deal with the overflows of water that occur every rainy season in the villages of Hative Kecil, Galala and Aster. This study aims to overcome water overflow caused by the accumulation of sedimentation on the riverbed so that there is no flooding, by backfilling the riverbed. The results of the analysis of this study indicate that most of the Way Ruhu river area has been damaged by water-fed land which has been turned into residential land which has resulted in flooding and landslides in the Way Ruhu watershed area. The sedimentation rate that occurs in the Way Ruhu river watershed averages every year of: 3,599 m3 / day or 1,313,635 m3 / year. So that the sedimentation that is carried out of the river is as much:32,386m³/ dayi atau 11.954.078 m³/ year
