Water On The Land

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.
