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 .
