A hydrological profile of a water resource.
A river has a flow regime determined by geology, topography, climate and vegetation.
The 5 components of a flow regime are:
1. Magnitude of discharge
2. Frequency of discharge
3. Duration of discharge
4. Timing or predictability of flows
5. Rate of change of flow: how quickly flow changes
Why is a flow regime important?
The flow regime determines the ecological integrity of a water resource.
