Morphometric analysis of a subtropical Andean basin (Tucumán, Argentina)
A morphometric analysis was done to determine the drainage characteristics of Lules River basin using land-sat imageries and topographical maps. This catchment was divided into seven sub-basins for the analysis: Liquimayo, Hoyada, CiĂ©naga, De Las Tablas, SiambĂłn, Potrerillo and San Javier. Yungas ecoregion covers almost all the watershed. The drainage patterns of the sub-basins are dendritic and parallel. The basin includes seventh order stream and lower streams order mostly dominate the basin. The development of stream segments is affected by slope and local relief. The mean bifurcation ratio indicates that the drainage pattern is not much influenced by geological structures. The shape parameters also reveal the elongation of the basin and sub-basins.Fil: Mesa, Leticia Mariana. Consejo Nacional de Investigaciones CientĂficas y TĂ©cnicas.
