La classificazione di Horton - Strahler, prevede una  classificazione basata su cinque regole: si definiscono "canali di primo ordine" gli elementi che hanno origine dalle sorgenti; dall'unione di due rami di ordine "n" ne deriva uno di ordine "n+1"; dall'unione di due rami di ordine diverso il confluente con ordine maggiore sarà il tratto di canale immediatamente a valle; la successione di due o più rami, caratterizzati dallo medesimo ordine "n", costituisce canali del loro stesso ordine; il canale caratterizzato dall'ordine più elevato "N" determina l'ordine stesso del bacino</gco:CharacterString>
