Performance Measurement on the Existing Operation Pattern of the Multi-Purpose Ladongi Reservoir

This study aims to assess the current operational framework of the multi-purpose Ladongi reservoir, which serves various functions including providing 120 L/s of raw water, irrigating 3,600 ha of land, controlling floods, potentially generating 1.3 MW via a Mini Hydro Power Plant, and supporting the tourism sector. The evaluation utilizes measurements of the reservoir's capacity to satisfy various requirements classified by three indexes: reliability, resilience, and vulnerability. The results indicate that the existing framework of the Ladongi reservoir has a reliability of 92.72% with an average deficit ratio of 7% based on 23 years of historical data. Based on the current operational scheme, the reservoir has a fairly high level of reliability and resilience translating to a considerable recovery duration from a failed period. Additionally, the maximum deficit ratio reaches 100% suggesting that in that period the reservoir cannot meet the target despite that the average deficit ratio is small, highlighting the variables that need to be optimized in the operation framework.
