- The hydrological cycle
- A rivers drainage basin is the area surrounding the river where the rain is falling
- This area is also called the rivers catchment
- The boundary of a drainage basin is the watershed
- Any precipitation falling beyond the watershed enters a different drainage basin
- Drainage basins are open systems with inputs and outputs
- Water comes into the system as precipitation and leaves via evaporation, transpiration and river discharge
- The water balance shows the balance between inputs and outputs
- In wet seasons precipitation exceeds evapotranspiration
- The creates a water surplus
- In drier seasons precipitation is lower than evapotranspiration
- In wet seasons precipitation exceeds evapotranspiration
- A rivers drainage basin is the area surrounding the river where the rain is falling
