Pengaruh Perubahan Tutupan Lahan Terhadap Aliran Permukaan Pada Sub - Das Kampar Kanan Dengan Menggunakan Model Hidrologi Swat (Soil Water Assessment Tool)

The research area is located in the right Kampar sub-watershed that crosses Riau and West Sumatra provinces. The result of the delineation process has formed 44 sub-watersheds with a total area of 447,221.10 ha. From the results of the study obtained 12 types of land closures, 5 types of land with a slope level of 0-25%. This study aims to analyze the effect of land cover changes on surface flow in the right Kampar sub-watershed using a SWAT (soil water assessment tool) hydrological model. There was an increase precipitation from 3866.33 mm to 4687.94. Significant changes occurred in the wateryield or the total amount of water entering the main river during the simulation period from 1722.65 mm to 3633.75 mm. Subsequent changes occurred in percolasi 1928.88 mm to 2337.95 mm. Similarly, the change to lateral Q was 47.58 mm to 72.24 and groundwater 1036.11 mm to 2214.21. Due to changes in land use, runoff or runoff is likely to increase from 647.63 mm in 2009 to 1356.34 mm in 2018. Calibration results using monthly debit data in 2010 - 2011 observations and predictions at SPAS Lake Bingkuang are 276.70 m3/dt and 354.98 m3/dt. The calculation result for the Nash-Sutcliffe coefficient (NSE) is 0.60 so that it can be interpreted to meet. While the value of R2 is 0.57 interpreted medium influence category. Meanwhile, validation results obtained by using monthly debit data in 2018 were 115.63 m3/dt and 93.03 m3/dt. The result of the calculation for the Nash-Sutcliffe coefficient (NSE) was 0.787 interpreted in good categories. While the value of R2 is 0.95. interpreted high influence categories.
