Influence of Sand and Gravel Moving as Bed Load on the Deformation Process of Clay Bed

Key Points

• This research aims to understand how sandy bed load influences the deformation of clay riverbeds under water flow.
• Conducted multiple experiments varying flow rate, sediment grain size, and sediment supply amount.
• Analyzed the effects of these parameters on the formation of microtopography and riverbed dynamics.
• Focused on conditions where erosion dominance leads to distinctive geometric patterns.
• Under conditions of predominant erosion, characteristic geometric patterns form on the riverbed.
• The formation of a mixed layer with sediment supply diminishes the effects of initial microtopography.
