This notebook explains how to derive a DEM-based unit hydrograph and how we can analyze the generated hydrograph directly with Python, to interpret the rising limb, peak flow and recession limb that are valuable to deepen our understanding of a flow in a channel.
Analysis can be done either using GIS desktop or purely with Python. For GIS desktop-based analysis, please refer to references.
- Python (Jupyter Notebook)
- GRASS GIS (via
grass.jupyterand scripting interface) - Digital Elevation Model (DEM)
- Hydrologic Modeling module within GRASS
