Dam Break Analysis of Salomekko Dam Using Zhong Xing HY21

Every Dam must have an emergency plan document in which there is a dam collapse analysis. Based on previous research, it is stated that dam collapse often occurs due to runoff and piping. In this case, the Dam that will be studied is Salomekko Dam, located in Bone Regency. Salomekko Dam is located in the Salomekko Hamlet of Ulu Balang Village, Salomekko Subdistrict, Bone Regency, South Sulawesi Province, which provides water for agricultural irrigation. Analysis of the collapse of the Salomekko Dam was carried out due to overtopping and piping. The stillness of the air overflows through the top of the Dam. At the same time, the piping is caused by seepage in the dam body, which carries the dam material gradually. Analysis of the Salomekko Dam collapse using the Zhong Xing HY21 application can produce maps of flood inundation distribution, flood outflow hydrographs, and flood times. Based on these results, it can also have a hazardous impact to define boundaries of disaster-affected areas.
