A Sensitivity Analysis Approach to Identifying Drivers of Streamflow Hysteresis

We study the critical interplay between streamflow hysteresis and local hydro-morphologic conditions. Hysteresis strength, which can lead to over 60% errors in discharge estimation with widely accepted monitoring methods, is primarily influenced by local characteristics such as bed slope, roughness, and event wave intensity. Our study used a 1D numerical model to highlight the hysteresis response to local hydro-morphological changes acting in isolation or combination. The sensitivity study entails gradual variation of the hydrograph intensity, backwater condition, bed slope (0.0001
