Short summary
In our study, we included bioturbation into a soil erosion model and ran the model for several years under two conditions: with and without bioturbation. We validated the model using several sediment fences in the field. We estimated the modeled sediment redistribution and surface runoff and the impact of bioturbation on these along a climate gradient. Lastly, we identified environmental parameters determining the positive or negative impact of bioturbation on sediment redistribution.
