Model Hydrology MockWyn-UB to Analyse Water Availability in Gumbasa Watershed Central Sulawesi Province
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 1
Abstract
From the results of previous studies stating that the watershed Gumbasa there has been a change in climate, discharge models used in calculating the availability of water in a watershed used the model MockWyn-UB Studies conducted Gumbasa watershed has an area of 1229.43 km2 with AW LR outlet Gumbasa River.Based on the analysis, the relationship between the discharge of models and the discharge observation forming a un iform pattern except in 2013 which discharge higher models of discharge observation. The correlation coefficient between the discharge and the discharge observation models do not qualify so the calibration data using the facility solver is not done. Thus the calibration is done using the Root Mean Square Error (RMSE). RMSE value MockWyn-UB acquired 3.10%. While the results of the analysis models Mock RMSE values obtained 8.03 %.Comparison between the using of model FJ. Mock and model MockWyn-UB with using test parameters RMSE statistics showed an error rate MockWyn-UB models better than models FJ. Mock. Model MockWynUB do not optimal if applied in the watershed Gumbasa, this is caused by the presence of Lake of Lindu are located in the basin Gumbasa.
