 Hi Matteo, now the link you provided for the JGrass source code works fine, you can take a look at the source code for more information about the extratc_network algorithms. Probably Riccardo can also help you > Does someone know what are the values of the parameters implemented > for the tangential stress in the II mode of extract network''? > I mean, \alpha that is the coefficient and n for the gradient \Nabla z ? > > PS: this link does not work anymore >> https://svn.dev.cocos.bz//svnroot/jgrass/jgrass3.0/branches/jgrass4udig1.1.x/trunk/eu.hydrologis.jgrass.models/src/eu/hydrologis/jgrass/models/h/> The last versions of JGrass are not included in the update site, so please download the full JGrass version you can find at the following link for the new releases: http://jgrass.wiki.software.bz.it/jgrass/InstallationWe are trying to solve the problems related to the JGrass/uDig update site, but it seems to be an issue for the uDig 1.2, and not uDig 1.1 (the actual stable version).
