Hack's relation and optimal channel networks: The elongation of river basins as a consequence of energy minimization Academic Article uri icon


  • As pointed by Hack (1957), river basins tend to become longer and narrower as their size increases. This work shows that this property may be partially regarded as the consequence of competition and minimization of energy expenditure in river basins. 1993 by the Chinese Geophysical Society
