geomorphic component - flat plains
- geomorphic component - flat plains
A group of fundamental, three dimensional pieces or areas of flat plains.
In descending elevational order, the geomorphic components of a simple, flat plain (e.g., lake plain, low coastal plain, etc.) are the rise [ a broad, slightly elevated area with comparatively greater gradients (e.g., 1-3% slopes ], and the talf [ a comparatively level (e.g., 0-1% slopes), laterally extensive, non-fluvial area ], and dip [ a slight depression that is not a permanent water body nor part of an integrated drainage network ].
Compare: geomorphic component - terraces.
