(Geomorphology, 2009-12-15) [Artigo]
The Upper Paraguay drainage basin is situated mainly in west-central Brazil. near the Bolivian border. Flowing from north to south, the Paraguay is the trunk river of an alluvial depositional tract characterized by complex ...
Remote sensing analysis of depositional landforms in alluvial settings: Method development and application to the Taquari megafan, Pantanal (Brazil)
(Geomorphology, 2012-08-01) [Artigo]
Traditional Shuttle Radar Topography Mission (SRTM) topographic datasets hold limited value in the geomorphic analysis of low-relief terrains. To address this shortcoming, this paper presents a series of techniques designed ...
