“…135 of 2018 [21]. This method is often used in many countries because the indicators produced are formulated based on their order of importance, making it easier for managers or stakeholders to make decisions in the context of priority [27,28]. The aspects reviewed in this rating are safety, operation, and physical condition in Indonesia, which have not been integrated with maintenance costs [9].…”

Potential risks to people exist if a dam collapses and has a significant impact on the downstream area. Many countries are now facing the problem of having to deal with deteriorated infrastructure due to a lack of maintenance budgeting. This paper presents the dominant parameter in an Operational and Maintenance (OM) dam to build a cost estimation model to maintain the service life of the dam. The method used to identify cost-triggering parameters is based on activity-based costing and dam performance assessments using a combination of the modified Andersen, International Commission of Large Dams (ICOLD), and Dam Commission. The parameter was collected from fourteen independent variables, namely: dam height, irrigation area, sedimentation volume, grass area, wood vegetation area, corrosion area, concrete area, daily worker, corrosion expert, concrete deterioration, hydromechanical, physical performance, operation performance, and safety performance. The results of the model indicate that height, wood vegetation area, concrete maintenance area, hydromechanical deterioration, and safety performance are variables that affect OM costs. The OM costs can be reduced if the safety performance variable increases. This condition implies that if the safety performance component consists of dam monitoring activities, periodic inspections, green belt maintenance, water quality maintenance, and public awareness, the OM costs will decrease by 10%.

“…It is a crucial part of India's energy and water security since it offers a variety of advantages, including irrigation, drinking water supply, flood control, hydropower generation, and recreation (Bassi, 2022). According to Zielinski et al (2022) Central Water Commission, India has more than 5,000 major dams, which collectively produce 13% of the nation's total energy and nearly 18% of its total capacity for water storage.Natural and human factors impact the quality and composition of dam water (Peters et al, 2000).…”

Aim: To assess the water quality of Kot Dam, located in the Jhunjhunu district of Rajasthan, India. Methodology: Physico-chemical parameters of water quality were monitored for two years (July 2021 to June 2023). The Water Quality Index (WQI), a widely accepted mathematical expression used to understand the trend in the quality of water bodies, was calculated based on the analysis of physicochemical parameters, including pH, total dissolved solids, hardness, alkalinity, dissolved oxygen, biological oxygen demand, chloride, sulphate, nitrate, calcium, magnesium, conductivity, and fluoride. Results: The site-wise and season-wise analysis of WQI revealed that Dam water was polluted due to organic pollutants, agricultural runoff, and waste disposal by local people, especially during summer (WQI=87.18) and monsoon seasons (WQI=85.38). Interpretation: Anthropogenic activities adversely affected the water quality at sample station (S1) of Kot Dam. Key words: Anthropogenic activities, Bray-Curtis Similarity Index, Dendrogram, Kot dam, Water quality

“…Here, the Delphi model was considered for determining subjective weights, a fuzzy evaluation method for assessing the safety of mine enterprises, and a bow tie model for identifying causes, and consequences, and allowing corresponding safety measures to be taken to guarantee the mine's safe production. Finally, Zielinski et al 9 developed a risk screening tool also based on bow tie methodology for helping to prioritize dam safety remedial projects for India's dam safety program, which could potentially be used for assessing other dams around the world as well.…”

This work focuses on the development of an approach considering the application of the bow tie methodology for monitoring and reporting the performance status of safety barriers used in collapse prevention of dams that store water for refinery process purposes, as well as for mitigation of the consequences in case of materialization of this scenario. After elaboration of the bow tie diagram in collaboration with technical specialists directly involved in dams' safety, the integrity of barriers is determined based on information collected from each dam at an operational level. Considering the literature review carried out, one of the most important contributions of this research (besides the bow tie diagram itself) consists in the proposition of a periodic reporting process of barriers performance indicators to managers responsible for each barrier in order to properly support risk management, permeating all the relevant technical and hierarchical levels (including communications upwards the board—top management). Its main motivation lies in lessons learned from several past major accidents, such as Macondo, Texas City, and, the Brumadinho catastrophe itself, regarding the need for safety information to “travel upwards” on the companies' hierarchy in order to properly and quickly support the decision‐making process, contributing to the strengthening of safety culture inside the organizations.
