Why is the River Dee important?
Because it provides Catchment for Sheep hill farming,Dairy Farming,Drinking Water,Indigenous Animals & Commercial/Recreational Fishing
6 of 17
How does the River Dee help Sheep Farming?
River valleys are cheaper- so farmers spend less money on land and use their flat land for growing crops. This means you save money from buying land and get more money from your livestock

When the Dee floods the floodplains, the land is dispursed with rich nutrients from the river. The cows eat the nutrious plants, making the milk better and better milk,brings in more money for farmers!

What is a Reservoir & why has it been built in the Dee?
Reservoir- a large lake, usually artifical, used to store water. Built on the Dee to store water for the summer, when there is less rainfall & not enough natural flow for people/industry.
13 of 17
What is Channelisation & Why was the Dee channelised?
Channelisation-the deepening and/or straightening of a river-to allow it to carry more water.The Dee was channelled to make river flow through the channel,more quickly-so takes it away from places at risk of flooding.
14 of 17
What are Embankments & why have they been built on the Dee?
Embankments- raised banks along a river and were put in place to protect farmland & properties, from flooding.
15 of 17
What are the physical factors changing the River Dee?
Drought & Heavy Rainfall & Climate Change
16 of 17
How does drought & heavy rainfall affect the River Dee?
Drought means the River Dee will flow slowly, as there's less water in the river. Heavy rainfall means the ground gets over-saturated & soil can't absorb anymore water= surface run off & risk of flooding
