Abstract
In this manuscript some DEM-based flow-direction methods and flat area treatment approaches are investigated. The standard procedure of widely used GIS software packages (ESRI ArcInfo and GRASS) is compared to some new recently proposed techniques analysing results obtained on a small sub-basin of the Tiber river. Differences of the new experimental procedures as respect to the standard approach are evaluated in term of some hydrogeomorphic variables and other hydrological design parameters.
