Moss-biofilm cover modulates hydrodynamic erosion on varied rock-surface morphologies under sheet flow

Key Points

• Hydrodynamic erosion is significantly altered by the presence of moss-biofilm, impacting rock shapes.
• In different rock-surface morphologies, moss-biofilm successfully reduced erosion rates by up to 45%.
• Analysis was conducted under controlled sheet flow conditions, examining various rock surfaces.
• Understanding moss-biofilm's role may lead to improved strategies for erosion control in natural environments.
