| |
| − |
| |
| − | RHydro is a set of topographical analysis tools that are not dissimilar to the ArcGIS ArcHydro toolbox (but more modest in scope). They are originally based on the [http://www.es.lancs.ac.uk/hfdg/freeware/hfdg_freeware_dta.htm DTM-ANALYSIS program] from the hydrology group at Lancaster University.

| |
| − | RHydro is experimental software and comes without any warranty. Currently it does not do much input checking but should be fairly save if used correctly.
