Abstract

The availability of water in the Pucak watershed is not always sufficient to meet all these needs simultaneously. This problem is exacerbated by climate change which causes changes in weather and erratic river flows. Climate uncertainty causes the weather to be unpredictable as it should be. This research aims to analyze the mainstay discharge of the Pucak Sub-watershed to ensure sustainable water availability. The analysis was carried out using daily discharge data for the last 10 years obtained from the nearest observation station. Data processing methods include the F.J Mock method and the Arithmetic method with certain reliability (Q80%, Q90% and Q99%). The research results show that the availability of water in the Pucak watershed for irrigation, raw water and hydroelectric power needs is met every month except in September. In the F.J Mock method the reliable Q80% discharge is 44.05 m³/sec, the Q90% discharge is 36.08 m³/sec and the Q99% discharge is 33.66 m³/sec. Meanwhile, the reliable Arithmetic method of Q80% discharge is 27.92 m³/second, Q90% discharge is 21.96 m³/second and Q99% discharge is 16.64 m³/second. These discharges are sufficient to meet various needs, but there is the potential for water shortages at the peak of the dry season

Abstract

The Makawa river basin located in the Rongkong watershed has an increase in surface flow which affects the discharge flow which can cause flooding. Therefore, discharge data is needed to manage existing water resources. This study aims to analyze the water discharge using the F.J. Mock and NRECA methods, which are then compared to the water estimation post discharge. The results of this study showed that the F.J. Mock method has a relative error of 48% and a correlation coefficient of 0,690 with a strong interpretation, while NRECA showed a relative error of 50% and a correlation coefficient of 0,669 with a strong interpretation. Therefore, it is concluded that the F.J. Mock method is more appropriate than the NRECA method with lower relative error results, and a higher correlation coefficient than NRECA. The result of the simulation discharge between F.J. Mock, NRACA and water estimation post discharge are quite far apart.
