Presentation transcript:

DRAINAGE PATTERN

Characteristics of river systems No river starts from a single point Rills Channels Ravines Streams (Tributaries) Main river No river ends at a single point Distributaries

Conclusion The entire river system including Tributaries Main river Distributaries Has a specific spatial arrangement

What is drainage pattern? The pattern that emerges due to the spatial arrangement of different components of the river system Tributaries Main river Distributaries

Type of Drainage Patterns Radial Trellised Dendritic Disappearing Combinations of one or more of the above

Radial Drainage pattern Hill in the centre Streams flow outward in different directions

Trellised Drainage Pattern Streams parallel to each other

Dentritic Drainage Pattern Random arrangement of streams

Disappearing stream Stream may disappear in its course due to Evaporation Flowing through sandy area

SETTELEMENT PATTERN

Types of Settlements Nucleated Dispersed Houses close to each other Strong social ties Dispersed Houses far away from each other People live in their own farms

Nucleated Settlement pattern Nucleated and Radial Place well connected with nearby places People engage in trade Nucleated and Linear Houses on the side of a road or river People depend on road or rive for livelihood Nucleated

Nucleated and Linear

Nucleated and Radial

Dispersed Settlement Pattern

MODES OF TRANSPORT

Modes of Transport Metre Gauge Railway Metalled Road Unmetalled Road

Modes of Transport Cart Track Pack Track Foot Path

The Chief mode of transport is the one that is used by a larger number of people in the map

MODE OF IRRIGATION

What is irrigation? Artificial means of availing water River is not a mode of irrigation Required if area receives seasonal rainfall

(Dry) tank with embankment Modes of irrigation (Dry) tank with embankment Dam Canal

Modes of irrigation Perennial lined well Perennial Unlined well Tubewell Perennial lined well with brackish water Brackish

Chief Mode of Irrigation One which is used by a larger number of people in the map In most cases would be perennial lined wells
