Synthetic Unit Hydrograph Development for Ungauged Basins Using Dimensional Analysis
The authors set out to determine average representative unit hydrographs (UHs) for the upper Kumbhi basin and the Dhamani basin in Maharashtra, India, from selected isolated storms. They developed an innovative approach using dimensional analysis techniques to establish an empirical model to determine synthetic UH (SUH) parameters for the upper Kumbhi basin. This method was used to select proper empirical relationships for SUH analysis for the ungauged basins with similar hydrological conditions. Results were then compared with the results obtained by other methods as well as the observed UH. To calibrate and validate the model's performance, the authors next applied the model to the Dhamani basin. Findings indicated that the peak discharge computed using the dimensional analysis technique provided minimum percentage error (–9.272%) and that the shape of the hydrograph matched the observed UH provided by the other methods.
