Short summary
In our study, we developed, tested, and applied a cost-effective time-of-flight camera to autonomously monitor rainfall-driven and animal-driven sediment redistribution in areas affected by burrowing animals with high temporal (four times a day) and spatial (6 mm) resolution. We estimated the sediment redistribution rates on a burrow scale and then upscaled the redistribution rates to entire hillslopes. Our findings can be implemented into long-term soil erosion models.
