LIMA, Kleber Carvalho; CUNHA, Cenira Maria Lupinacci da  e  PEREZ FILHO, Archimedes. RELATIONSHIP BETWEEN DRAINAGE NETWORK AND SEMI-ARID PLANATION SURFACES. Mercator (Fortaleza) [online]. 2016, vol.15, n.2, pp.91-104. ISSN 1984-2201.  https://doi.org/10.4215/RM2016.1502.0006.

Ephemeral and intermittent drainage networks are important factors for the understanding of planation surface evolution in semi-arid areas. Currently, this subject is rarely studied in the Brazilian geomorphological literature. In this paper, we explored this topic and we identified the different levels of planation surface, we analyzed the superficial coverage and the drainage channels characteristics and we analyzed the dissection of landforms. The results showed that the different levels of conservation and dissection of the planation surface is related to the fluvial process, as well as the elaboration of geomorphological compartments is related to different spatial patterns of the drainage network.

Palavras-chave : network; Planation surface; Semi-arid.
