Abstract

The dam failure that has been operating has a great potential to occur if the administrator does not carry out proper maintenance. Dams require proper and correct maintenance and operation which will greatly affect the safety of the dam itself. Especially for dams that have been operating for a long time, major maintenance activities including repairs and rehabilitation are urgently needed to avoid the worst conditions such as facing natural disasters. Because a dam can cause a large impact if it fails, it is necessary to have a risk assessment to analyze and evaluate the hazard of the dam. Risk research conducted at the Nglangon Dam uses the event tree method, traditional and modified ICOLD. Based on the results of individual and group extreme probability analysis, both traditional and event tree methods, the risk probability value is above the acceptable risk value threshold of 1.00E-05, which means that the Nglangon Dam requires further action. This is in line with the results of the ICOLD modified risk assessment method with classification III (high) which means that the Nglangon Dam is included in a dam that requires special attention and corrective actions to reduce the level of risk in the Nglangon Dam

Abstract

Evapotranspiration is a key parameter used in run-off modelling. The Bulango Ulu Dam, located near the equator where sunlight is at its peak throughout the year, makes evapotranspiration a crucial factor in analysing water availability. This research aims to analyse the performance of two evapotranspiration calculation methods on the accuracy of run-off modelling to the Bulango Ulu dam. The study employs the modified Penman and Thornthwaite evapotranspiration methods as input to Mock's model. The Analysis indicates that the Mock-Penman method outperforms the Mock-Thornthwaite method, with statistical parameter results of MAE 0.963, NSE 0.891, R 0.949 and Kr 1.3%, Therefore, it concludes that the run-off modelling aligns with the observed flow value
