Abstract
Dam failure risk management is a crucial aspect in ensuring public safety and the sustainability of water resource infrastructure. Dams not only serve as a source of water for irrigation, power generation, and domestic needs, but also pose a significant hazard in the event of structural failure. Therefore, well-planned risk management is a must. One of the main strategies in reducing the level of risk is through the appropriate allocation of budget for remedial work. This study focuses on the Woro Dam, Parado Kanca Dam, and Sumi Dam with the aim of analyzing the extent to which budget allocation can affect the reduction of failure risk. The methods used include risk analysis and budget sensitivity analysis by comparing various financing scenarios with the value of failure risk. The results show that an increase in the remedial budget can generally reduce the risk value, although the extent of the reduction varies for each dam. Factors that influence these differences include the initial condition of the structure, technical characteristics, and the type of remedial work carried out. Interestingly, the relationship between the size of the budget and the reduction in risk is not always linear, so the effectiveness of the handling is more determined by the accuracy of the priorities and the quality of the work implementation. Thus, dam risk management is not only about allocating a large budget, but also about ensuring that the budget is allocated appropriately and that the work is carried out effectively.
