Measured geometric parameters and measurement methods.
| Measured parameter | Unit | Method |
|---|---|---|
| Perimeter (P) | m | Contour of the depression |
| Area (A) | m2 | Surface of the depression |
| Length (L) | m | Defined by the line extending from the upstream part to the downstream part |
| Width (W) | m | Largest distance orthogonal to the length line |
| Height (H) | m | Calculated from the topographic profile (length line) |
| Slope min (Smin) | degree | Minimum slope along the length line |
| Slope mean (Smean) | degree | Mean slope along the length line |
| Slope max (Smax) | degree | Maximum slope along the length line |
| Elongation (El) | – | El = L/W |
| Circularity (C) | – | C = 4πA/P2 |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
