In fact, the trellised and rectangular patterns are differentiated on the basis of spacing between the streams. These streams resemble the spokes of a wheel or the radii of a circle. Radial Drainage Pattern 5. They develop where the river channel follows the slope of the terrain. Centripetal. Drainage pattern a pattern created by stream erosion over time that reveals characteristics of the kind of rocks and geologic structures in a landscape region drained by streams. Image Guidelines 4. Page 22 WATER 34. What does this type of drainage pattern indicate about the area? The Tamar Kosi, a left bank tributary of the Kosi River, the upper Rapti (a tributary of the Ghaghra River), the Rapti (another one), the left bank tributary of the Gandak River etc. (ii)When the primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles, the pattern is known as ‘trellis’. Petrified Forest National Park, Arizona, USA . Trellised drainage patterns are formed by the network of tributaries and master consequent streams which follow the regional slope and are well adjusted to the geological structures. Content Guidelines 2. The Kathmandu valley of Nepal presents an ideal example of centripetal drainage pattern wherein the tributary streams of the Baghmati converge in the tectonically formed circular basin. These rills are further ex­tended in length and width and become channels. The courses of the tributaries are straight­ened because of slope factor and little distance be­tween the ridges and the longitudinal consequents occupying the valleys and thus the tributaries are not allowed to adapt sinuous course and join the longitudi­nal consequents at acute angles (fig. 17.8 (1)] but with the passage of time a dense mesh of multitudes of tributaries of various hierarchical orders is developed and thus the initial open network becomes a ‘closed pattern’ as the streams are very closely spaced. A. 17.12) is developed over a mature and dissected dome mountain characterised by a series of alternate bands of hard and soft rock beds. The difference:(i) The drainage pattern resembling the branches of a tree is known as “dendritic” the examples of which are the rivers of northern plain. Dendritic or tree-shaped drainage pattern is the most common and widespread pattern to be found on the earth’s surface. This pattern also resembles the rectangular pattern. What drainage pattern dominates this area? Dendritic Drainage Patterns. Drainage Patterns We have defined drainage pattern and discussed both the dendritic drainage pattern and the trellis drainage pattern. dendritic drainage pattern: translation    A common drainage pattern in which the tributaries join the gently curving mainstream at acute angles, resembling in plan view the branching habit of an oak or chestnut tree; it is produced where a consequent stream receives several tributaries which in turn are fed by smaller tributaries. The tributaries join their master streams in a hook-shaped bend. 4 Common Types of Drainage Patterns Dendritic. Dendritic drainage patterns develop in areas where the rock type is uniform and the land is gently sloping. Dendritic or Pinnate Drainage Pattern This is an irregular tree branch shaped pattern. Parallel drainage pat­tern has also developed on the Eastern Coastal Plains of India. Trellised drainage patterns are generally formed in the regions of cuesta topography where hard beds become escarp­ments and soft beds are eroded to become valleys or lowlands. A. Radial drainage patterns form when rivers 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. Eg: R. Indus, R. Mahanadi, R. Godavari, etc., In Trellis Drainage Pattern the tributaries (Subsequent rivers) joins the original river at right angles and the tributaries flow parallel to each other. The local upland situated to the south-west of Ranchi city has given birth to radial drainage pattern wherein the South Koel, the Subarnarekha, the Kanchi and the Karo rivers take their sources and radiate in different directions. Centripetal. dendritic drainage A drainage pattern that may develop on homogeneous rock, which has a shape resembling the pattern made by the branches of a tree or the veins of a leaf. composed of sandstones capping and the peneplained surface of the central Ranchi plateau composed of granite-gneisses have favoured extensive dendritic drainage pattern while elongated dendritic pattern has developed along the middle and lower segments of the escarpments associated with these plateaux. The lengths of the individual channels in a dendritic drainage pattern are _____ and this increases energy _____. *The dendritic pattern develops in the areas where the underlying rock structure exerts no control. Dendritic definition is - resembling or having dendrites : branching like a tree. A radial drainage pattern occurs when They form in areas with flat and uniform bedrock like sandstone or shale. Pinnate pattern is developed in a narrow valley flanked by steep ranges. A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. 17.14). Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. First of all the master or trunk consequent stream develops on gently sloping topographic surface. 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. A fourth type of drainage pattern, which is not specific to a drainage basin, is known as radial (Figure 13.8, right). Dendritic drainage pattern – looks like the branching of a tree, found in regions with homogenous material. The rocks are weathered and eroded along the interfaces of joints, fractures and faults and thus sur­face runoff collects in such long and narrow clefts (resulting from the weathering and erosion of joints) and forms numerous small rills. DENDRITIC DRAINAGE. Copyright 9. Forms in regions with gentle slopes and similar materials, a pattern similar to the veins in a tree leaf Rivers, such as the Amazon, form a pattern like the branches of a tree? A dendritic pattern develops in a terrain which has uniform lithology, and where faulting and jointing are insignificant. A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. Dendritic drainage: stream networks that branch in a tree-like fashion.Dendritic drainage patterns tend to develop on surfaces that erode uniformly on gentle to moderate slopes. Parallel 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. Disclaimer 8. This pattern is formed by a series of streams which after emerging from surrounding uplands converge in a central low land which may be a depression, or a basin or a crater lake. What type of drainage pattern is shown in Figure I to the right? Deranged. 2.Parallel drainage pattern- forms where there is a slope. Report a Violation 10. Slope and permeability of rocks very effec­tively control the number and extension of streams of dendritic drainage pattern. Rectangular pattern is generally developed in the regions where the rock joints form rectangular pattern. Dendritic patterns ( see figure ), so called because of their similarity to branching organic forms, are most common where rocks or sediments are flat-lying and preferential zones of structural weakness are minimal. The significance of drainage patterns in determining regional geologic history has been known for over a century. Herringbone drainage pattern, also known as rib pattern (like the rib bones of human beings), is developed in mountainous areas where broad valleys are flanked by parallel ridges having steep hillside slopes. Major tributary streams of the master stream develop on either side of the trunk stream (fig. The Republic of South Yemen lies on the edge of one of the world's great sand seas, the Rubh-al-Khali, but even this dry desert region bears the unmistakable imprint of flowing streams and rivers. Though den­dritic pattern is independent of structural and lithological controls but almost uniform lithology (presence of same type of rocks in extensive area) presents most ideal condition for the development of dendritic drain­age pattern. This pattern resembles the veins of a leaf. With the march of time a network of streams is developed wherein streams follow the lines of weakness (joints and fractures). A drainage pattern which looks like tree branches with lots of twigs is known as Dendritic drainage pattern. It develops in regions underlain by homogeneous material. (ii) When the rivers originate from a hill and flow in all directions, the drainage pattern is known as ‘radial’. The second line of difference between these two drainage patterns is re­lated to the spacing of streams i.e. Source for information on dendritic drainage: A Dictionary of Ecology dictionary. A Dictionary of Ecology. present ideal examples of radial drainage pattern. In other words, this pattern is likely to develop wherever there are no major geological factors influencing drainage patterns. Dendritic Pattern - *Dendritic Pattern is a tree like pattern. Trellised Drainage Pattern: Trellised drainage patterns are formed by the network of tributaries and … views updated. This is an irregular tree branch shaped pattern that develops in a terrain which has uniform lithology (uniform rock structure), and where faulting and jointing are insignificant. Courtesy of National Aeronautics and Space Administration In a series of tilted sediments the differential erosion of softer units, such as clay and shale, results in valleys developed perpendicular to the dip or tilt of the units. April 2020. 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. In a dendritic system, there are many contributing streams (analogous to the twigs of a tree), which are then joined together into the tributaries of the main river (the branches and the trunk of the tree, respectively). That is, the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take. Trellised Drainage Pattern 2. This pattern develops in a variety of structural and lithological environments such as in the mountainous and hilly areas (e.g., dendritic pattern is one of the dominant patterns in the Himala­yas), on extensive plateau surfaces (e.g., Deccan plateau), on peneplain surfaces (e.g., the Peninsular peneplains of India, mostly in the basins of the Mahanadi, the Godavari, the Krishna, the Cauvery, the Domodar etc. The drainage network of dendritic pattern becomes most extensive if the land surface is characterized by flat surface, level to gentle slopes and impermeable rocks. Annular drainage pattern has developed over denuded domes in the Weald of England. dendritic pattern A branching, treelike drainage pattern. 17.15). , Drainage Patterns Dendritic, Trellis, Rectangular, Radial, 16 Mahajanpadas and their modern locations, 73rd Constitutional Amendment Act and Panchayat Raj, 74th Constitutional Amendment Act of 1992 and Municipalities, Administrative Relations between Centre and State, ALL INDIA TRADE UNION CONGRESS 1920 (AITUC), Cultural developments in early Medieval India, Anglo Gurkha War 1814-16 and Treaty of Sugauli, Art and Architecture in post Mauryan period, Battle of Buxar 1764 and Treaty of Allahabad-1765, Coastal Plains – East Coastal and West Coastal, Complete list of Governor Generals of India 1772 to 1950, Components of Biosphere abiotic, biotic, energy, Difference between Himalayan and Peninsular Drainage System, Difference between Legislative Assembly and Legislative Council, Difference between Natural Hazard and Disaster, Direct Action campaign of Muslim League – 1946, Distinction between Fundamental Rights and Directive Principles, Distribution of Minerals and Energy Resources in India, Earth’s Atmosphere Horizontal Distribution of Air Pressure, Earth’s Atmosphere Vertical Distribution of Air Pressure, Electoral System and Election process in India, Financial Relations between Centre and State, First Anglo Sikh War 1845-46 and Treaty of Lahore, First Anglo-Maratha war 1775-82 Treaty of Surat, Forms of condensation – Dew, Frost, Smog, Mist and Fog, Geographical Distribution of Roads in India, Heating and cooling of the atmosphere-Radiation, Conduction, Convection, Advection, HINDUSTAN SOCIALIST REPUBLICAN ASSOCIATION, Horizontal Distribution of Temperature on the Earth, India’s Economy Prior to the Country’s Independence, Indian Economy at the time of independence, Industrial Policy statement 1969 and 1970, INDUSTRIES AND CRAFTS IN THE HARAPPAN CIVILIZATION, Inequality-adjusted Human Development Index (IHDI), Influence of Distance from the Sea on the Climate of India, Influence of El – Nino on the Climate of India, Influence of Location and Latitudinal Extent on the Climate of India, Influence of Northeast and Southwest Monsoon Winds on the Climate of India, Influence of Southern Oscillation on the Climate of India, Influence of the Northern Mountain Ranges on the Climate of India, Influence of Upper Air Circulation – Westerly Jet stream and Easterly Jet stream, Influence of Western Disturbances and Tropical Cyclones on the Climate of India, Integrated scheme of oil seeds, pulses, maize and oil palm (ISOPOM), Landforms of Glacier- Cirque, ‘U’ shaped, Hanging Valley, Law-making Procedure in the Parliament – Ordinary Bills and Money Bills, Legislative Assembly vs. Geomorphologists and hydrologists often view streams as being part of drainage basins. It is obvious that dome structures, volcanic cones, batholiths and laccoliths, residual hills, small tablelands, mesas and buttes, and isolated uplands favour the develop­ment of ideal radial pattern (fig. oxford. Important Drainage Patterns: (i) The drainage pattern resembling the branches of a tree is known as “dendritic” the examples of which are the rivers of northern plain. Dendritic or Pinnate Drainage Pattern. dendritic drainage | Encyclopedia.com Skip … Rectangular drainage patterns form as a result of. A dendritic drainage pattern is the most common type. Dendritic Drainage Pattern, Yemen. Such pattern is generally developed due to river capture (fig 17.13). Dendritic drainage patterns are tree like while trellis drainage patterns are formed when tributaries meet at right angles so they look like squares or rectangles. Radial B. Rectangular C. Dendritic D. Trellis 9. Rectangular drainage patterns form as a result of. Pinnate Drainage Pattern 9. all of these. The streams emerge at the central point of the aforesaid reliefs and drain down the slopes in all directions. It may be pointed out that a sub-parallel pattern is, therefore, essentially an ‘initial drainage pattern’ (fig. The dendritic pattern develops where the river channel follows the slope of the terrain.The stream with its tributaries resembles the branches of a tree 16 Mahajanpadas and their modern locations 5000 Solved Gk questions 73rd Constitutional Amendment Act and Panchayat Raj Annular Drainage Pattern 7. Drainage which is branching or ramifying (branch out or cause to branch out) thereby giving the appearance of a tree. Drainage patterns The pattern of fluvial dissection of a landscape is of considerable importance in understanding the structural influence on drainage evolution. Radial drainage patterns form when streams and rivers flow off a central peak or dome like a volcano. Herringbone Drainage Pattern 10. 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. Forms in regions with gentle slopes and similar materials, a pattern similar to the veins in a tree leaf Rivers, such as the Amazon, form a pattern like the branches of a tree? Barbed drainage pattern, a rare kind of drainage pattern, is formed when the tributaries flow in opposite direction to their master streams. the rectangular pattern is characterized by widely spaced trbutaries while trellised pattern has a dense mesh of closely spaced tributaries. 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. The evolution of dendritic pattern is guided by the lithological characteristics mainly the permeability of underlying rocks, the amount and regime of rainfall and resultant surface runoff and the time factor.
