摘要：Flood disaster in Rokan Hulu Regency often occurs every year. High streamflow conditions during rainy season as one of the causes of the flood. Stream’s Regime Coefficient (KRS) is the ratio of maximum and minimum discharge in a watershed that shows the watershed condition. The higher KRS means the worse the watershed condition. The study areas are located in the upstream Rokan watershed. Upstream Rokan watershed with the AWLR (Automatic Water Level Recorder) Lubuk Bendahara and Pasir Pangaraian in Riau Province were picked up as study area of this research. The results show the indicator of stream’s regime coefficient at Lubuk Bendahara AWLR valued 217.45 which placed on poor class and the indicator of stream’s regime coefficient at Pasir Pangaraian AWLR valued 38.25 which placed on good class.
