Development of an open source Debris Flow Simulator for “Sabo” (DFSS)

We report the development of an open source “Debris Flow Simulator for Sabo” (DFSS). DFSS consists three models corresponding to geomorphological regions (mountain hillside slopes, mountain-to-plain river channels, and lower plains). A 2D rainfall-runoff (RR) model is adopted mainly slopes; a 1D debris flow runoff (DR) used channel; flooding or inundation (DF) plains. These are weakly coupled such that one can modify overall fit diverse problems. In this article, we provide detailed introduction comprising DFSS, demonstrate its utility.
