What Is a Trellis Drainage Pattern?

Bihar province presents a good example of radial drainage pattern wherein the Karamnasa and the Durgawati rivers and their source tributaries emerge from the south-western corner of the plateau and flow in the western, north-western, northern, and north-eastern directions whereas the tributaries of the Son River flow in the southern direc­tion. Tributaries joining a larger stream at acute angle less than 90 degrees. The streams called subsequent rivers cut out the valleys called vales and join the main river called Consequent River at right angles. A drainage pattern in which the streams branch randomly in all directions and at almost any angle, resembling in plan the branching habit of certain trees. It is known as Tsangpo before it turns to south into Indian Territory. Rectangular forms distinct changes in direction rectangles because the streams follow less-strong rocks.

Over the next few centuries, this creek will seek to become graded again by eroding down through its own alluvial fan. Radial Drainage Pattern : Radial drainage pattern, also known as centrifu­gal pattern, is formed by the streams which diverge from a central higher point in all directions. The rivers that occupy many glaciated valleys, including the gap ofdunloe, also have trellis pattern. Trellis drainage is characteristic of folded mountains, such as the in North America and in the north part of. Hazaribagh plateau, Parasnath hill, Panchet hill and Dalma lava upland all in Jharkhand have issued radial drainage pattern.

The differential erosion of hard and soft rock beds results in the truncation of the beds which produces ringed belted structure wherein relatively resistant beds project outward whereas the weaker soft beds form circular clefts. The water leaving the dam has no sediment in it. In India the range shows the best example of radial drainage pattern. Dendritic patterns form when a kind of random motion occurs. Millions of pilgrims bathe in the Ganga, Yamuna and Godavari.

All of these options cost, and the idea for the use of the land will have to come together with the availability of financing to determine which method or options will work best in any given application. It happens in areas where there has been much geological disruption. 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. Rivers of the northern plains rise in the Himalayas and beyond it. Chapter 7, Origins of Stream Valleys and Drainage Patterns. The west­ern coastal plains of India represent several examples of parallel drainage patterns where the streams after taking their sources from the western flanks of the Western Ghats drain in straight courses towards west to empty into the Arabian Sea.

With the march of time a network of streams is developed wherein streams follow the lines of weakness joints and fractures. The discharge of river Brahmputra is the greatest of any Indian river. When the Earth emerged from the last Ice Age, the Sahara and the Rubh-al-Khali were savannah grasslands with a more temperate climate and much higher rainfall than they experience today. This map illustrates the concept of a drainage basin divide. The number, size, and shape of the drainage basins found in an area varies and the larger the topographic map, the more information on the drainage basin is available. Ungraded streams have steep sections at various points, and typically have rapids and waterfalls at numerous locations along their lengths.

Rock and sand don't really hold water and will drain it effectively. The branching pattern in the photograph could only have been produced by running water, draining off the surrounding land. It is best displayed by streams draining a maturely dissected structural dome or basin where erosion has exposed rimming sedimentary strata of greatly varying degrees of hardness, as in the Red Valley, which nearly encircles the domal structure of the Black Hills of South Dakota. In fact, the trellised and rectangular patterns are differentiated on the basis of spacing between the streams. The longitudinal consequent streams, as master streams, are developed in the longitudinal parallel valleys while tributaries, as lateral consequents, after originating from the hillslopes of the bordering paral­lel ridges join the longitudinal consequents almost at right angle. Nature of river Long course, flowing through the rugged mountains experiencing head ward erosion and river capturing; In plains, meandering and shifting off course.

Land can be graded and shaped to our needs, but this is probably a job for a contractor. A parallel pattern also develops in regions of parallel, elongate landforms like outcropping resistant rock bands. Such patterns are devel­oped in the area of simple folds characterised by parallel anticlinal ridges alternated by parallel synclinal valleys. Indus rises beyond the middle ranges of the Himalayas. In the Indian sub-continent too, rivers have played a major role in civilization growth. An example of a drainage basin is shown in Figure 13.

The Rivers of Peninsular India can be grouped into three main drainage systems. A variant pattern, in which trunk streams run subparallel, can occur on tilted strata. The drainage network of the upper Son and Narmada rivers denotes the example of pinnate drainage pattern. For example, rivers in the upper part of the Himalayan region. Additionally, the problem is a 3-dimensional one, and a cross section of the subsurface features over the area of interest will have to be plotted. Water has basically only a couple of ways to leave an area. Trellis drainage patterns typically develop where sedimentary rocks have been folded or tilted and then eroded to varying degrees depending on their strength.

This pattern may form on top of the land surface or below the land surface in karst aquifers with anastomoses forming the smaller tributaries. Trellis forms long lines the rivers with tiny streamsjutting out at all sides. The two join at Devaprayag to form the mainstream known as Ganga. Dendritic drainage: the , Tibet, seen from space: snow cover has melted in the valley system. Many such water channels form a trellis. The tributaries originating from the steep sides of parallel ridges join the longtitudinal master consequent occupying the valley at acute angles fig. They are invariably lost in the sands.
