# The geomorphologic structure of hydrologic response

@article{RodrguezIturbe1979TheGS, title={The geomorphologic structure of hydrologic response}, author={Ignacio Rodr{\'i}guez‐Iturbe and Juan B. Valdes}, journal={Water Resources Research}, year={1979}, volume={15}, pages={1409-1420} }

A unifying synthesis of the hydrologic response of a catchment to surface runoff is attempted by linking the instantaneous unit hydrograph (IUH) with the geomorphologic parameters of a basin. Equations of general character are derived which express the IUH as a function of Horton's numbers RA, RB, and RL; an internal scale parameter LΩ and a mean velocity of streamflow v. The IUH is time varying in character both throughout the storm and for different storms. This variability is accounted for…
