River Wye

Question 1

Geomorphic process that have shaped the river + climate

Answer 1

725mm average rainfall
Plynlinouth hills 2500mm
Rapid river flows and high erosion causing mass movement
Low temperatures at source resulting in v shaped valleys

Question 2

Influence of geology in the formation of the river

Answer 2

Upper course - impermeable shale ->doesn’t absorb water -> higher volume of water -> higher flow rate -> faster -> erosion - cleddon falls
Rhayader - rapids
South of Hereford - sweeping meanders - mudstones
Lower course - levees and floodplains are formed due to material deposit in the middle course

Question 3

Impact of management

Answer 3

Lakes - storage lakes have been constructed above the town as a surplus of water (letton lakes)

Flood wall - walls that are placed to protect the city from flooding. 200 homes at 5 million

Flood plains - parts of town that are deliberately left to flood

Tree planting - helped stabilise slopes reduce mass movement,will also affect natural formation of levees
Reduce flood height by 20%

Question 4

How human activity influenced the geomorphic process in the landscape

Answer 4

• in the 1700s the river was used for tourism,rock climbing, canoeing, kayaking
• trees were used up but replanted since ww2
• used for agriculture due to the irrigation from river
• limestone quarrying results in change in gradient
