Witryna2 wrz 2024 · Horton-Strahler’s ratios of stream ordering (the bifurcation ratio, R B, the length ratio, R L, and the area ratio, R A,) are commonly used to characterize scale properties of basins and to calculate the geomorphological instantaneous unit hydrograph (Rodríguez‐Iturbe and Valdes 1979; Rosso 1984; Rodríguez‐Iturbe and Rinaldo 1997 ). WitrynaThe use of the Nash IUH allows an analytical framework to be defined which assesses the relationship between the maximum dimensionless peak and the n -structure exponent for a given dimensionless duration, and similar analytical derivation can be carried out for simple synthetic IUHs. burgess vs fdicWitrynaRosso R., 1984.
