Concentration-Discharge relationships are a key tool for understanding the sources and transport of material from watersheds to fluvial networks. Turbidity based estimating of suspended sediment concentration is widely used for river studies due to its simply and cheap using. The relation between suspended sediment concentration (turbidity) and discharge is not normally homogenous and often producing hysteretic loop. Therefore, this work identified the hysteresis types of the turbidity-discharge relationships in river Ose. Data were collected at coordinates 7⁰ 18’ 35.5” N and 5⁰ 39’ 52.5” E for two-year period and analysis showed that counter-clockwise hysteresis loop pattern was dominant. This suggested that overland flow is much possible in the study area.
