Fecha de publicación: | 2017 | Editor: | Indian Academy of Sciences | Citación: | Current Science - New Delhi 112(5): 996-1002 (2017) | Resumen: | A total of 216 sculpted forms were registered on the granitic bedrock of the Miño River, northwest Iberian Peninsula. Analysis of in situ measurements (length, width and depth) revealed three general type-sets: incipient forms, longitudinal furrows and circular pot-holes. Maximum depth and upper radius (at the incision surface) were identified as key variables to mathematically determine the growth rate in each set. Three regression models are presented revealing that the development of the forms depends on a power law explaining their size and shape. Morphological and dimensional thresholds were established to better identify stages from incipient active growth) and inherited (stationary growth) forms | Descripción: | 7 páginas, 4 tablas, 6 figuras | Versión del editor: | http://dx.doi.org/10.18520/cs/v112/i05/996-1002 | URI: | http://hdl.handle.net/10261/147350 | DOI: | 10.18520/cs/v112/i05/996-1002 | ISSN: | 0011-3891 |
