Trellis Drainage Pattern Diagram

This type of drainage occurs in an eroded dome and is rarely observed. Trellis Drainage Pattern.

Dendritic-this pattern resembles branches of trees.

Trellis drainage pattern diagram. The old folded mountains of the Singhbhum have drainage of trellis pattern. Trellis Drainage Pattern In an earlier laboratory we identified two drainage patterns on the Cumberland quadrangle. Usually the drainage patterns dendritic trellis etc are strongly influenced by the hardness and softness of the rock and patterns of faults or fractures.

The name of each pattern Identify each of the patterns on diagrams. Also known as the Trellis drainage system or the Trellis River pattern is the one that we can mostly find across the Southern regions of a map. All forms of transitions can occur between parallel dendritic and trellis patterns.

For example rivers in the upper part of the Himalayan region. August 3 2016 by Chuck Bailey. Trellis drainage pattern is formed when the primary tributaries of main rivers flow parallel to each other and secondary tributaries join them at right angles.

A trellis drainage pattern develops where hard and soft rocks exist parallel to each other. Identify stream patterns on topographic maps. We have also indicated that a trellis drainage pattern indicates structural.

Annular drainage is a pattern of concentric circles that are connected by short radial stream segments. A rectangular drainage pattern develops on a strongly jointed rocky terrain. Trellis pattern develops where hard and soft rocks exist parallel to each other.

Sometimes however the land rises rapidly relative to the base level of the stream. Radial patterns form around isolated mountains such as volcanoes or hills and the individual streams typically have dendritic drainage. Geomorphologists and hydrologists often view streams as being part of drainage basins.

It is marked by right-angled junctions between tributaries and their mainstream. Accordant versus discordant drainage patterns. Trellis or espalier drainage patterns result from adjustment to tight regional folding in which the folds plunge.

Denudation produces a zigzag pattern of outcrops and adjustment to this pattern produces a stream net in which the trunks are aligned on weak rocks exposed along fold. When the streams flow in different directions from a central peak or dome like structure a radial pattern is developed. This increases the gradient of the stream and therefore gives the stream more erosive power.

Experts define the Trellis Drainage pattern as the indication of structural control by varying types of eroded and folded sedimentary rocks. Per the lie of channels drainage systems can fall into one of several categories known as drainage patternsThese depend on the topography and geology of the land. We looked at the dendritic drainage pattern of Rush Run and we identified the drainage pattern over the southern part of the map as being trellis.

When rocks are strongly joined then rectangular pattern develops. SE A fourth type of drainage pattern which is not specific to a drainage basin is known as radial Figure 138 right. Figure 137 Typical dendritic trellis and rectangular stream drainage patterns.

Ex the indo-gangetic plains. A region that has prominent parallel and perpendicular faults repeated folds or a strong rectangular jointing pattern will display a rectangular or trellis drainage. Trellis drainage pattern in the Valley Ridge at the headwaters of the James Potomac and Ohio river systems in northwestern Virginia and eastern West Virginia.

Ex the old folded mountains of chotanagpur plateau. It is important. There are 4 types of drainage patterns on the basis of their flowing pattern-dendritic trellis radial and rectangular.

Trellis-in this pattern tributaries join the main rivers at right angles. Other articles where Trellis drainage pattern is discussed. Drainage pattern is the pattern formed by the streams rivers and lakes in a particular drainage basinThey 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.

It is indicative of streams following prominent fault or joint systems. Seven drainage patterns Dendritic Trellis Radial Rectangular Centripetal Deranged Parallel caused each of the drainage patterns You must know the following with regard to drainage patterns. Trellis drainage is characteristic of folded mountains.

A drainage basin is the topographic region from which a stream. A drainage system is described as accordant if its pattern correlates to the. A drainage pattern in which the main streams and their tributaries display many right-angle bends and exhibit sections of approx.
