The researchers used remote sensing technology to predict water flow in the Unda watershed in Bali. By analyzing land use and soil type maps, they calculated the predicted flow rate using the SSCN method. Over the past decade, they found fluctuations in discharge, with the highest being 10,569 m3/s in 2013 and the lowest at 0.079 m3/s in 2010. The average discharge for different sub-watersheds ranged from 0.163 m3/s to 8.068 m3/s.
