RHydro

Introduction
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 DTM-ANALYSIS program from the hydrology group at Lancaster University.

For a fully documented example, see the Digital terrain analysis with RHydro page.

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