Criteria for distinguishing elementary landscapes_
| Elementary landscapes | Index | Landforms | Morphometric parameters | ||
|---|---|---|---|---|---|
| TPI | Slope | Curvature | |||
| Eluvial | E | Flat watershed surfaces | >1SD | <5 | 0, + |
| >1SD | 3–10 | + | |||
| Transeluvial (moderate offset) | TE2 | Slopes of medium steepness | −1SD | 5–10 | −, 0, + |
| Transeluvial (low offset) | TE1 | Gentle slopes | −1SD -0 | <5 | 0, + |
| Transeluvial-accumulative | TeA | The foot of the slope | −1SD − 0 | <3 | −, 0 |
| Super-aquatic | Sa | Depressions and ravines, floodplains | <- 1SD | <3 | − |
