  text: Accurate assessment of erosion rates remains an elusive problem because soil
    loss is strongly nonunique with respect to the main drivers. In addressing the
    mechanistic causes of erosion responses, we discriminate between macroscale effects
    of external factors—long studied and referred to as “geomorphic external variability”,
    and microscale effects, introduced as “geomorphic internal variability.” The latter
    source of erosion variations represents the knowledge gap, an overlooked but vital
    element of geomorphic response, significantly impacting the low predictability
    skill of deterministic models at field-catchment scales. This is corroborated
    with experiments using a comprehensive physical model that dynamically updates
    the soil mass and particle composition. As complete knowledge of microscale conditions
    for arbitrary location and time is infeasible, we propose that new predictive
    frameworks of soil erosion should embed stochastic components in deterministic
    assessments of external and internal types of geomorphic variability.
