1. The drainage basin hydrological cycle: The Systems Theory:

3. What is the Hydrological cycle? Recap our hydrological cycle homework- does anyone need to redo? The hydrological cycle is an example of a system – Write a definition of the concept of a system

6. The global hydrological cycle is closed. Drainage basins are open systems interconnected to other systems.

7. Look at fig. 1.3: What are the Main Inputs?… What are the main flows (or transfers) or stores? What are the main outputs? Think about how humans might influence the hydrological cycle.

8. Check you have completed your shaded systems model to show inputs, flows and transfers and outputs.
