This research analyzed the morphological/morphometric parameters of relief and drainage network Formiga River subbasin, southern Minas Gerais State, Brazil. study identified examined influences control mechanisms in development current configurations. The methodology was based on application indices parameters: (1) slope length (Hack's Sl); (2) normalized index (ksn); (3) river hierarchy; (4) d...
Triangulated surfaces are often used to represent terrains in Geographic Information Systems (GIS); one of the primary computations on terrains is determining drainage networks. Under natural deenitions of the ow of water on a terrain represented by n triangles, we show that the river network has (n 3) worst-case complexity, where complexity is measured in the number of line segments that make ...

[1] Low internal relief, aridity, and internal drainage characterize the Puna-Altiplano Plateau and the Tibetan Plateau and the Tarim basin. Structurally, these areas are reverse fault bounded terrains with intervening wedge-top basins that store thick accumulations of sediment for millions of years. Orographic barriers along the margins of these basins are oriented normal to moisture bearing w...
Vulnerability analysis of urban drainage networks plays an important role in urban flood management. This study analyzes and compares the vulnerability of tree and loop systems under various rainfall events to structural failure represented by pipe blockage. Different pipe blockage scenarios, in which one of the pipes in an urban drainage network is assumed to be blocked individually, are const...
