Última Relations between hidrogeomorphic attributes of the Dourados basin-Brazil and their enviromental signficance Agrociencia Samantha Alcaraz,Omar Daniel; Tadeu-Vitorino,A. Carlos; Sannier,Christophe. The study of the morphometry within of catchment boundaries allowed to quantify aspect of the fluvial system in relation to geology, geomorphology and hydrology of the basin of Dourados river, Brazil, making possible to analyse the relations between hydrographic and environmental properties like the first step to better understand the processes taking place within the catchment area. The drainage network was described using qualitative and dimensional observations, from which significant quantitative attributes were derived, including interpolated drainage density and drainage frequency. Environmental data such as geology, geomorphology and soils type were acquired to allow an interpretation of their relationships with the drainage network. The...

Ano: 2011 URL: http://www.scielo.org.mx/scielo.php?script=sci_arttext&pid=S1405-31952011000300001 Comparison of methodologies for automatic generation of limits and drainage networks for hidrographic basins AGRIAMBI Alcaraz,Samantha A.; Sannier,Christophe; Vitorino,Antonio C. T.; Daniel,Omar. The objective of this work was to compare methodologies for the automatic generation of limits and drainage networks, using a geographical information system for basins of low relief variation, such as the Dourados catchment area. Various data/processes were assessed, especially the ArcHydro and AVSWAT interfaces used to process 50 m resolution DTMs formed from the interpolation of digitalized contour lines using ArcInfo, ArcView and Spring GIS, and a 90 m resolution SRTM DTM acquired by interferometry radar. Their accuracy was estimated based upon the pre-processing of small basic sub-basin units of different relief variations, before applying the best combinations to the entire Dourados basin. The accuracy of the automatic stream network generation and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Watershed; Catchment; Geographic information systems.
