OpenAI's Answer
To create a geomorphologic instantaneous unit hydrograph (GIUH), you typically need the following specific data:
-
Catchment Area Characteristics:
- Watershed area and shape
- Stream network configuration
- Slopes and elevation data
-
Geomorphological Parameters:
- Horton-Strahler stream order
- Drainage density
- Bifurcation ratios
-
Hydrological Data:
- Rainfall intensity and distribution
- Runoff data, though GIUH can be useful in ungauged catchments where this is scarce
These inputs help in modeling the runoff response of a watershed based on its physical characteristics without the need for extensive hydrological data collection.
For more in-depth details and case studies, check the sources like The GIUH Method Overview and Velocity Parameter Estimation.
