What is meant by drainage pattern?

What is meant by drainage pattern?

Drainage patterns or arrangements refer to spatial relationships among streams or rivers, which may be influenced in their erosion by inequalities of slope, rock resistance, structure and geologic history of a region. ... At first the pattern produced by the stream will depend on the slope of the initial surface.

How are rectangular drainage patterns formed?

Trellis drainage patterns typically develop where sedimentary rocks have been folded or tilted and then eroded to varying degrees depending on their strength. ... Rectangular patterns develop in areas that have very little topography and a system of bedding planes, fractures, or faults that form a rectangular network.

What are the four types of drainage patterns?

there are 4 types of drainage patterns on the basis of their flowing pattern-dendritic, trellis, radial and rectangular.

Which is the most common type of drainage pattern?

dendritic drainage pattern A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It develops in regions underlain by homogeneous material.

What are the 3 types of drainage patterns?

Drainage patterns

• Dendritic drainage pattern.
• Parallel drainage pattern.
• Trellis drainage pattern.
• Rectangular drainage pattern.
• Radial drainage pattern.
• Centripetal drainage pattern.
• Deranged drainage pattern.
• Annular drainage pattern.

What are the three types of drainage patterns?

• Dendritic drainage pattern.
• Parallel drainage pattern.
• Trellis drainage pattern.
• Rectangular drainage pattern.
• Radial drainage pattern.
• Centripetal drainage pattern.
• Deranged drainage pattern.
• Annular drainage pattern.

What is the most common drainage pattern?

dendritic drainage pattern A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It develops in regions underlain by homogeneous material. That is, the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take.

What are the three drainage patterns?

Drainage patterns

• Dendritic drainage pattern.
• Parallel drainage pattern.
• Trellis drainage pattern.
• Rectangular drainage pattern.
• Radial drainage pattern.
• Centripetal drainage pattern.

• Annular drainage pattern.

What are the 4 types of drainage patterns Class 9?

Different types of drainage pattern are as follows:

• Dendritic Drainage Pattern: When the river channel follows the slope of the terrain, it develops dendritic pattern. ...
• Trellis Drainage Pattern: When a river is joined by its tributaries at almost right angles, it develops a trellis pattern.

What are the types drainage pattern?

Drainage pattern types include annular drainage pattern, centripetal drainage pattern, dendritic drainage pattern, deranged drainage pattern, integrated drainage pattern, karst drainage pattern, lack of drainage pattern, parallel drainage pattern, radial drainage pattern, rectangular drainage pattern, thermokarst ...

What are drainage patterns and different types of drainage pattern?

Drainage patterns are formed by the streams, rivers and lakes in a particular drainage basin. They are governed by the topography of the land whether a particular region is dominated by hard or soft rocks and gradient of land. Thank you for your feedback! Your feedback is private.

How are streams and drainage basins related to each other?

They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologist s and hydrologist s often view streams as being part of drainage basins. A drainage basin is the topographic region from which a stream receives runoff, throughflow, and groundwater flow.

Which is the best description of a rectangular drainage system?

Rectangular drainage pattern. The result is a stream system in which streams consist mainly of straight line segments with right angle bends and tributaries join larger streams at right angles. This pattern can be found with the Arun River in Nepal.

What is the definition of a deranged drainage system?

A deranged drainage system is a drainage system in drainage basins where there is no coherent pattern to the rivers and lakes. It happens in areas where there has been much geological disruption.
