Water on the land
In this unit students gain an understanding of rivers and their landforms, flooding, and how rivers are managed. There are seven key ideas in this unit:
- The shape of river valleys changes as rivers flow downstream due to the dominance of different processes.
- Distinctive landforms result rom differenent processes as rivers flow downstream
- The amount of water in a river fluctuates due to a number of reasons
- Rivers flood due to a number of physical and human causes. Flooding appears to be an increasingly frequent event
- The effects and responses to floods vary between areas of contrasting levels of wealth.
- There is discussion about the costs and benefits of hard and soft engineering and debate about which is the better option.
- Rivers are managed to provide a water supply. There are a variety of issues resulting from this.
