Title : Surface Run-off Coefficient in the Lake Area for Supporting the Reduction of Surface Run-off

Abstract :

This research intends to investigate the existing run-off coefficient based on the land use in the area of Batur, Bratan, Buyan, and Tamblingan Lake (Bali, Indonesia). The value is used for knowing how big the run-off volume that has to be reduced so there is no flooding in that area. The methodology consists of overlaying the land use map and then multiplying it with the run-off coefficient The run-off coefficient is as the function of design flood, rainfall intensity, and land use. The result shows that the run-off coefficient of Batur Lake is 0.37; Bratan Lake is 0.38; and Buyan Lake is 0.36. However, the run-off coefficient mean is 0.37
