Collapse Analysis

Abstract 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.

Flood Risk Map

The flood risk map is useful to make a regional flood emergency plan and analyze the dam-break flood risk. A three-dimensional mathematical model is applied to simulate the floods evolution with consideration of the dam-break process and the complex boundary condition synthetically, and the finite volume method is used to get a discrete solution. The flood evolution process of Dongwushi reservoir in the instantaneous collapse conditions is taken as a case, and the flood risk map is obtained based on the results of calculation.

Abstract Many of Iraqi's high-hazard dams lack an Emergency Action Plan, which should include a flood inundation map to show which downstream areas would be flooded if the dams were to fail. This article presents the results of the simulation of a hypothetical 2D dam break for the 58 m high Khassa Chai dam in Kirkuk, Iraq, using HEC-RAS 2D 5.0.7 software. The Khassa Chai dam is situated 7.4 kilometers north of Kirkuk. The simulations revealed that the dam-break flood will affect eight major bridges and the majority of Kirkuk city's metropolitan neighborhoods. Within an hour, the floodwaters will reach the city's center. The flood hazard map revealed that if the Khassa Chai dam fails, many people, vehicles, and structures will be at danger. The findings of this paper can be used to identify evacuation routes and refuge sites as well as build suitable warning systems in order to limit the risk for fatalities if the Khassa Chai dam fails. Moreover, as the effect of modelling bridges downstream of failed dams has not been explored yet, to the knowledge of the authors, eight bridges have been modeled. It was concluded that ignoring bridges in such a large dam break model will not affect the results significantly, which saves the time of data collection and model development.
