This review, by no means exhaustive of the publications on this subject, collects in a reasonably organic manner some relevant theoretical developments and a few significant applications.Hydrological responseTravel time distributionsUnit hydrographsDrainageGeomorphologyGraph theoryRiversRunoffGeomorphological theoryHydrological responseTravel time distributionsUnit hydrographsHydrologygeomorphological theoryhydrological responserunoff hydrographsolute of transporttravel timeunit hydrographtext::journal::journal article::research article
