DRAINAGE & SETTLEMENT PATTERNS LESSON 7

Drainage Patterns 5 types of drainage patterns can be identified on a topsheet 1. TRELLIS PATTERN / RECTANGULAR PATTERN 2. DENTRITIC PATTERN 4. RADIAL PATTERN & 3. PARALLEL PATTERN 5. DISAPPEARING PATTERN

TRELLIS PATTERN TRIBUTARIES ARE SEEN MEETING THE MAIN STREAM AT A RIGHT ANGLE. THE DRAINAGE SYSTEM THAT THUS DEVELOPS LOOKS SOMEWHAT RECTANGULAR.

DENDRITIC PATTERN THE MOST COMMON DRAINAGE PATTERN. TRIBUTARIES COME FROM ALL DIRECTIONS TO MEET THE MAIN RIVER. LOOKS SOMEWHAT LIKE TREE BRANCHES.

PARALLEL PATTERN MANY RIVERS RUN PARALLEL TO EACH OTHER.

RADIAL PATTERN STREAMS DIVERGE FROM A CENTRAL HIGHER POINT IN ALL DIRECTIONS. ALSO CALLED AS CENTRIFUGAL PATTERN

DISAPPEARING PATTERN TRIBUTARIES DISAPPEAR INTO THE SOIL BEFORE REACHING THE MAIN RIVER. MOSTLY FOUND IN REGIONS OF LIMESTONE ROCKS.

SETLLEMENT PATTERNS 4 MAIN TYPES OF SETTLEMENT PATTERNS FOUND ON TOPO-SHEETS : NUCLEATED, DISPERSED, LINEAR & RADIAL

NUCLEATED OR COMPACT PATTERN NUMBER OF HOUSES BUILT CLOSE TO ONE ANOTHER

DISPERSED PATTERN ISOLATED SETTLEMENTS SCATTERED IN AN AREA. ALSO CALLED AS SCATTERED SETTLEMENT.

LINEAR PATTERN DEVELOP ALONG ROADSIDES, RIVERS, CANALS OR A RAILWAY LINE SO THAT EVERYONE CAN TAKE ADVANTAGE. FORM A RIBBON LIKE PATTERN.

RADIAL PATTERN LANES OF HOUSES DIVERGE IN VARIOUS DIRECTIONS FROM A COMMON POINT.
