Annular Drainage Pattern

Annular Drainage Pattern - Web figure 13.2.1 13.2. Distribution of stream courses and their spatial relationship to one another. Web a drainage pattern in which streams flow in a nearly circular or concentric pattern along with a weak rock band, resembling a ring in the plan, is said to be the annular drainage pattern. Web drainage patterns are classified on the basis of their form and texture. It refers to the system of flow of surface water mainly through the forms of rivers and basins. Web the basic drainage patterns are dendritic, parallel, trellis, rectangular, radial, annular, multibasinal, and contorted. The blue line shows the extent of the drainage basin. Web 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. Drainage pattern which looks like tree branches is known as dendritic drainage pattern. The main stream, often called the trunk stream, and all of the tributaries, as well as the tributaries of tributaries, and so on.

Web A Drainage Pattern In Which Streams Flow In A Nearly Circular Or Concentric Pattern Along With A Weak Rock Band, Resembling A Ring In The Plan, Is Said To Be The Annular Drainage Pattern.

Annular pattern, also known as ‘circular pat­tern’ is formed when the tributaries of the master consequent streams are developed in the form of a circle. Web drainage patterns are classified on the basis of their form and texture. The dashed red line is the drainage basin of one of its tributaries. Tree like branching or veins of leaf pattern formed by streams is dendritic pattern.

Web Angular Drainage Pattern.

The drainage system depends upon factors such as slope of land, geological structure, amount of volume of water and velocity of water. Join prelims cum mains course 2025 now. Web the basic drainage patterns are dendritic, parallel, trellis, rectangular, radial, annular, multibasinal, and contorted. A drainage basin is a portion of the earth's surface that contains a main stream and its tributaries and is bounded by a drainage divide.

Distribution Of Stream Courses And Their Spatial Relationship To One Another.

Annular drainage pattern in a dictionary of environment and conservation » Radial drainage may develop on a smooth dome or a volcanic cone. They have ring like planes. Their shape or pattern develops in response to the local topography and subsurface geology.

Drainage channels develop where surface runoff is enhanced and earth materials provide the least resistance to erosion. Web rectangular patterns form where drainage lines are adjusted to sets of faults and marked joints that intersect at about right angles, as in some parts of ancient crustal blocks. This is because the rock is weak, which means that it is very porous, allowing a lot fo water to flow into it. In an annular drainage pattern streams follow a roughly circular path, creating a ring like pattern.
