Three geomorphological instantaneous unit hydrograph (GIUH) models are investigated. These GIUHs were derived as a function of watershed geomorphological characteristics. The geomorphological input parameters of the models were determined for 10 basins in Indiana, USA. The three GIUH models were used to simulate 187 observed runoff hydrographs of these basins. The non‐measurable velocity parameters of the GIUH models were optimized and the relationships between them were investigated. The results of the investigation show that the velocity parameters of the three models are correlated. © 1998 John Wiley & Sons, Ltd.
