About

Maintained by Luca CarraroFirst published 2019-12-1818 releasesCRAN page ↗GitHub ↗

Generate and analyze Optimal Channel Networks (OCNs): oriented spanning trees reproducing all scaling features characteristic of real, natural river networks. As such, they can be used in a variety of numerical experiments in the fields of hydrology, ecology and epidemiology. See Carraro et al. (2020) doi:10.1002/ece3.6479 for a presentation of the package; Rinaldo et al. (2014) doi:10.1073/pnas.1322700111 for a theoretical overview on the OCN concept; Furrer and Sain (2010) doi:10.18637/jss.v036.i10 for the construct used.
