A drainage pattern refers to the arrangement of rivers, streams, and other bodies of water in a particular area. It is a result of the way water flows through the landscape, shaped by factors such as the topography, geology, and climate of an area. Understanding drainage patterns is important for a variety of purposes, including water management, urban planning, and natural resource management.

There are several types of drainage patterns that can occur in nature. The most common include dendritic, trellis, radial, and rectangular patterns.

A dendritic drainage pattern is characterized by a network of streams and rivers that resemble the branches of a tree. This type of pattern is typically found in areas with a gentle slope, where water flows in a relatively straight path from the highlands to the lowlands.

A trellis drainage pattern is similar to a dendritic pattern, but the streams and rivers are more closely spaced and form a crisscrossing pattern. This type of pattern is often found in areas with alternating bands of hard and soft rock, which create a series of ridges and valleys.

A radial drainage pattern occurs when streams and rivers flow outward in all directions from a central point, like the spokes of a wheel. This type of pattern is typically found in mountainous or volcanic areas, where a single peak or volcano serves as the central point.

A rectangular drainage pattern is characterized by straight, parallel streams and rivers that flow in a perpendicular direction to the topographic features of the area. This type of pattern is often found in areas with a flat or gently rolling topography and a uniform type of rock or soil.

In addition to these four main types of drainage patterns, there are also several hybrid patterns that can occur. For example, an annular drainage pattern is a combination of a dendritic and a radial pattern, while a deranged drainage pattern is a pattern that does not fit into any of the other categories.

Understanding drainage patterns is important for a variety of reasons. For example, in urban planning, understanding the drainage pattern of an area can help planners design and build infrastructure, such as roads and buildings, in a way that is sustainable and minimizes the risk of flooding. In natural resource management, understanding the drainage pattern of an area can help identify potential sources of water and help prioritize conservation efforts.

Overall, drainage patterns play a critical role in shaping the landscape and shaping the way we interact with it. By understanding these patterns, we can better manage and protect our natural resources, and build sustainable communities that are able to thrive in harmony with the natural environment.

A variety of linear, sinuous, rectangular, parallel, and dendritic patterns are common to all wetlands. Various forms of weathering on the joint systems or faults in any bedrock localize the streamflow, leading to the production of a Rectangular pattern. What is drama and its types? Modified from Clayton L, Attig JW, and Mickelson DM 1999 Tunnel channels formed in Wisconsin during the last glaciation. These tributaries also intersect at right angles where the water gap cuts through some more complex formations. Often, sediment collects into bars or other bedforms, only mobilized during times of significant runoff when the power of the stream is great enough. These laws are readily illustrated by plots of number and average length on logarithmic scales against order on an arithmetic scale. The discordant drainage pattern follows the initial slope and is unaffected by the alterations in the path.

Dendritic drainages are the most widespread, taking their name from a resemblance to the outline of a tree Figure 2. Here the mainstream and its tributaries resemble the branches of a tree. Trellis Drainage Pattern 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. Novel mechanism of stream formation in coastal wetlands by crab—fish—groundwater interaction. As these courses are followed into the unvegetated areas, the network suddenly develops in a well-defined dendritic pattern with sinuous to meandering courses.

To the best of my knowledge, there is no previous discussion about the processes giving rise to these connections, but they can be hypothesized to be the result of capturing by a headward retreat of one course into another adjacent. Marsh course watershed was estimated by connecting end points of first-order courses. The consequent system is developed by the general direction of the slope. It is important as a homeowner to know the flow of water, and learning these patterns is important. Such a pattern of drainage may develop from a volcano or conical mountain. Discordant Drainage Pattern: The drainage patterns that are not influenced by the topography and the slope of the areas, follow their initial path even after witnessing alterations in the course. Drainage patterns are governed by the topography of the land.

Consider the following statements: 1. Formation and Flow in a Trellis Drainage Pattern Diagram and Actuality By the time the erosion wears away the surface and exposes the folded sedimentary rocks below, the streams stay there. The patterns described above are accordant, or correlated with the structure and relief over which they flow. The formations must also be reflective of height and accentuated by erosion. Density of depressions is an important factor in course initiation and development because depression interconnection may lead to course formation. For instance, a dendritic pattern can be disrupted due to any external reasons, leading to the formation of a deranged pattern. Their forms or pattern develops in response to the local topography and subsurface geology.

The drainage patterns indicate the type of topography and gradient of the land. The flowing water can erode the soft rocks and thus flows along the bands of soft rock. The study notes provided by Vedantu on the types of drainage patterns can be studied by class 11 students who are pursuing geography, however, these notes are also useful for UPSC aspirants as geography holds a substantial weightage in the exam held by the UPSC. It is mainly found where the hard and soft rocks exist parallel to one another. In: Black R, Goldthwait R, and Willman H eds.

Drainage patterns Dendritic drainage pattern. Slow mountain building permitted stream erosion to keep pace with uplift Earle, 2019; Tarbuck et al. If the base level lowers or raises quickly through a tectonic event or a catastrophic weather event, the physical processes that control water and sediment behavior will begin to adapt to the new conditions within the watershed. The topography of a region also determines land-use patterns and the patterns and intensity of erosion and landslides. In flat plains, the gentle slope reduces the velocity of flow leading to formation of meanders and flood plains. A drainage pattern can be well briefed concerning the topological features from where a stream gets runoff through its flow and the groundwater flow. It finds its resemblance with the branching of the tree roots.

It is segregated into two types of drainage patterns such as consequent drainage pattern, and subsequent pattern. It is majorly segregated into two patterns, concordant and discordant drainage patterns. An area drained by a single river is called its drainage basin or catchment area. Which is the best description of a radial drainage pattern? Formation and Flow in a Trellis Drainage Pattern Diagram and Actuality By the time the erosion wears away the surface and exposes the folded sedimentary rocks below, the streams stay there. The drainage patterns are influenced by various factors such as the topography of the land, slope etc which leads to its various types. This leads to the formation of newer slopes and streams on the slopes, and these then become the tributaries for the mainstream in the area. Drainage is a well-defined channel constructed to direct the flow of water.

I have seen houses being sold to counties just so the county or city can build a drainage area for flood runoff. On these features the drainage may exhibit a combination of radial patterns. In other areas, tunnel channels occur as isolated, hanging, channel sections adorning uplands without integration to other channels or modern drainage. There are four major types of drama: comedy, tragedy, tragicomedy, and melodrama.

Law of stream numbers: the numbers of streams of different orders in a given drainage basin tend closely to approximate an inverse 2. Tributaries join the main stream at nearly right angles. While major rivers Sabarmati, Narmada, and Tapti discharge the sediments into the Gulf of Khambhat, the Luni river joins the Arabian Sea at the Gulf of Kutch.
