Table 6 Summary of the models predicting rut depth in fine-grained and mid-grained soils. The proportion of soil type refers to the number of sample plots falling into the specific category out of all sample plots (e.g. 5/6 means that five sample plots out of six samples fall into the specific category)

Allman et al. (2017) | – | 5/6 | 1/6 | RUT = 4.52 + 0.24 × GVC |
Sirén et al. (2019a) | – | 1/7 | 6/7 | ln(RUT) = 0.285 + 0.000011 × mass + 0.016 × VWC |
