2. Pattern of Rural Settlement
 Pattern of settlement has been defined by Emrys Jones
(British Urban Geographer).
 Topographical maps are the easiest way to study pattern
of settlements.
 Surrounding topography and terrain influences pattern
of settlement.
 Cultural factors and functional needs are also
responsible for shaping a settlement.

3. Pattern of Rural Settlement
The rural settlements may be broadly classified under the
following patterns:
• Rectangular pattern
• Linear pattern
• Circular and semi-circular pattern
• Star like pattern
• Triangular Pattern
• Nebular pattern

4. Pattern of Rural Settlement
Rectangular pattern
• Most of the people inhibit in this type of settlement.
• Develops primarily in productive alluvial lands.
• Roads are straight and cross at right angle.

5. Pattern of Rural Settlement
Linear pattern
• Houses are arranged along road, railway line, river or
canal. Also found along edge of valley or coastline.
• In case of hilly areas development pattern is guided by
terrain and topography.
• Along river bank and seashore water level is important
factor for linear settlement.
• Transportation routes also play an important role.

6. Pattern of Rural Settlement
Circular and semi-circular pattern
• Fisherman and salt producers develop their settlements
along sea coasts and salt lakes in this pattern.
• Semi-circular development grows along the bend of
streams.

7. Pattern of Rural Settlement
Star like pattern
 The star like settlements develop on the site where
number of roads meet.
 Dwelling units spread out along the roads.

8. Pattern of Rural Settlement
Triangular Pattern
• Triangular patterns generally develop at the confluence
(i.e. junction) of rivers.
• The lateral expansion of houses at the confluence
constrained by the rivers.

9. Pattern of Rural Settlement
Nebular pattern
• The shape of a settlement resembles to nebula, it is
known as a nebular settlement.
• Circular pattern of roads end at the center of the
settlement.
• The size of nebular settlements is small and develops
around the house of an influential person or place of
worship.

10. Pattern of Rural Settlement in Bangladesh
Nucleated Settlement
• Found in northwest in the Barind region (Varendra Bhumi).
Assumes a rectangular, square or circular form. Some
nucleated settlements in Barind area are quite large with 2
to 4 hundred families.
• Settlements are arranged in clustered pattern.
• The path coverage at the village, but there is no definite
path system.
• This is the common type of settlement pattern in
Chittagong Hill tracts.
• In Sylhet Basin area this type of settlements are found on
artificially built mounds (hillocks).

11. Pattern of Rural Settlement in Bangladesh
Linear Settlement
• In the active delta region, linear villages have been
formed on only one side of the river.
• Found in the Barind, in the moribund delta region
(Jessore, Kushtia, and Faridpur) or in areas where river
erosion is no longer active. These types of settlement are
found on both side of the river.
• Agricultural land may create gaps among different linear
settlement.
• Settlements in char land are often linear.
• This is the dominant type of settlement on the bank of
Jamuna, Mahananda, Tista, Ganges and the hilly valleys
of Chittagong.

12. Pattern of Rural Settlement in Bangladesh
Disperse Settlement
• Found in fertile flood plain where heavy inundation takes
place during the rainy season. People build their houses
by raising the homestead land with earth generally by
digging a pond.
• Very little communication exists among the settlements.
• This type of settlement common in haor areas of greater
Sylhet and Mymensingh.

13. Pattern of Rural Settlement in Bangladesh
Compact Settlement
• These are matured nucleated settlement.
• The density and number of population is very high in this
type of settlement.
• Usually have a very good communication and
transportation system with the other settlement.
Scattered Settlement
• Settlements are arranged in irregular pattern.
• Distance between settlements is negligible.
• This is the common type of settlement pattern in northern
and coastal Bangladesh.
