The Rhone Delta - A level OCR Geography

The Rhone flows into the Mediterranean sea to the west of

• Marseilles

• Bordeaux

• Paris

• Dordogne

The two major distributaries that feed the Rhone are

• The Ganges and Thames

• The yellow river and the Nile

• The Sienne and the Aude

• The grand Rhone and Petit Rhone

What area do the rivers divert north of

• Allier

• Arte

• Arles

• Aude

The last glacial ended 12000 years ago but how long ago did the Rhone start to develop (years)

• 10000

• 6000

• 7000

• 3000

The Rhone delta is what shape

• Cuspate

• Arcuate

• Lobate

• Birds foot

What is the main process responsible for shaping the delta

• Wave action

• Fluvial flows

• Human management

• Wind

Select the correct statements

• The dominant wind direction (SW) typically has low wind speeds

• The high levels of sediment ablation from river deposition have created a gently sloping coastal landscape.

• The high levels of sediment accumulation from river deposition have created a gently sloping coastal landscape.

• The enclosed Mediterranean sea means fetch distances are relatively short in all directions

What was the estimated deposition in 1900

• 17 million m3/yr

• 51 tonnes/min

• 17 million m2/yr

• 50 tonnes/sec

What is the main reason for the high deposition rate

• The sticking together of silt particles

• Flocculation

• Small tidal range (0.5)

• The meeting of two water bodies

Waves from the SSE and ESE bring

• Low energy waves with 1m wave heights on average

• High energy waves of 2m or more

• High energy waves that are dissipated over the delta

• A range of waves based on the season
