3. Coastal Geomorphology is branch of Geography that deals
with shaping of coastal features. The process it work on them
and changings taking place, coastal line change measured
over specified period with analyses of their causes. It also deal
with near shore process and responses particularly on
beaches it also deal with place and coastal evolution
Coastal Geomorphology Definition

5. Study Area
Coastal Geomorphology of Pakistan
And Deal with Coastal process and their impact on coastal features of
Pakistan.
6. A zone in which coastal process operate
or have a strong influence. Coast is
erosional feature .
Coast
9. Secondary Coast:
It is formed by sea influence,
erosion by wave
Two Types of Coasts
Primary Coast:
Land Base agency like river,
wind, desert, tectonic activity
10. Beach is a depositional feature it is an a
accumulation on the shore of generally
loose sediment ranging in size from very
fine sand up to pebbles, cobles and
occasionally boulder often which shelly
material a beach covers about 40% of
world coastline.
Beach
14. Beaches supplied with fluvial sediment.
Beaches supplied from eroding cliffs and fore shores.
Beaches supplied with sediment from sea floor.
Beaches supplied with wind blown.
Beaches made are modified by human activities.
Types of Beaches
15. Cliffs are steeps usually more than 400 often vertically and
some times over hanging coastal slopes cut into rock
formation they are generally receding as the result of marine
erosion at their base, accompanied by sub aerial erosion of
the cliff face. Many cliffs are fronted by shore plate form
exposed as the tide fall. Three quarters of word coastline is
cliffs and rocky.
Cliffs are strongly influenced by geology of coastal region

18. It is a depositional land form.
A narrow bar of sand deposit around the
coast. Spits are beaches built above high
tide level and diverging from coast
usually ending in one are more land
ward hocks are re curve.

21. A portion of land connect main land by
sand.
Or
tombolo's are wave built ridges of beach
material that link island, or attach a stack
or island to the main land
Tombolo

23. A sand is a elongated ridge on the bank
of sand a few meter wide deposited and
shape by wave and current it have
extensive parallel to the coastline and
sub merge at-least a high tide
Sand Bar

25. A bay is a small body of
water which has big mouth
and bay is surrounded by
three side of water the best
example of bay sonmiani
bay of Pakistan in Arabian
sea.
Bay
26. Gulf
A deep inlet of the sea almost surrounded by land, with a narrow mouth.
27. It is a feature of coast a land that goes deeper in the sea.
Cape
28. Arch is a natural opening eroded out of cliff face marine process.
Arch
29. A portion of land that just out of sea.
Head Land
30. It is a mouth of river where river
falling to the sea.
Estuary Delta
Delta is a land form created by deposition of
sediment that carry by river as the flow leaves its
mouth and inters slower moving or stagment that
occur where a river inter an ocean.
