Drainage: Lake and East Flowing Rivers
Drainage:
• The term “drainage” describes the river system of an area.
• The area drained by a single river system is called a “drainage basin” or river basin.
• Any higher ground, such as mountain or upland separates two adjoining drainage basins. Such upland is known as a water divide or a watershed.
• Depending upon the relief, geological structure and climatic conditions of the area, the streams form different patterns.
Drainage Pattern:
• Drainage of an area is concerned with the study of main rivers and their tributaries with respect to their size, number, direction of flow, drainage basin, slope of the valley.
• A drainage system refers to the origin and development of stream through time.
• Drainage pattern means spatial arrangement and form of drainage system in terms of different rock types, geological structure, climatic conditions and denudational history.
• 1. Trellis Pattern: in this system the tributaries can be seen meeting the main stream at right angles. This exists where hard and soft rocks exist parallel to each other.
• 2. Dendritic Patterns (Tree shaped pattern): is the most common and widespread pattern to be found on the earth’s surface. In this pattern, the tributaries come from all directions to meet the main river. Like the branches of a tree the small streams meet larger streams and the larger streams meet the much larger streams, in the end they meet the river. This develops where the river channel follows the slope of the terrain.
• 3. Parallel Drainage Patterns: comprises numerous rivers which are parallel to each other and follow the regional slope. This pattern is developed on uniformly sloping areas such as coastal plains.
• 4. Radial Drainage Pattern/Centrifugal Pattern: develops where streams flow in different directions from a central peak or dome like structure. Streams which diverge from a central higher point in all directions.
Drainage System of India:
On the Basis of origin, two broad drainage

    Much of the region of western New York State north of the Pennsylvania border has dendritic drainage because rock layers are flat and there are few faults or folds to divert streams. A region that has prominent parallel and perpendicular faults, repeated folds, or a strong rectangular jointing pattern will display a rectangular drainage pattern. (Joints are cracks in bedrock along which no significant movement has occurred. They may be related to expansion or regional forces acting on bedrock.) Streams seek the lowest areas of folds, fractured rocks along faults, or the weakest surface…

    . The hypothesis that was created as to what process formed the parallel groves was, The Glacier Theory. What occurred in this process was that, 15 thousand years ago, the whole section was covered with flowing ice that had huge boulders underneath it. When the ice dragged the boulders over the bedrock that was pressing against it, the smaller particles of the ice that were dragged created the grooves, which are called striations. This process is still acting on rocks because things like the Anartic sheets still exist, and these were created in the “Ice Age”, which was the period of time where there was an expansion in the ice sheets. By observing the rock you can picture the ice sheets, with huge boulders scratching.…

    Since primary school, we have learnt about 2D tessellation, which can also be found in our mother nature. When basaltic lava flows they mostly have cracks on them caused by contraction forces, creating columns of harden lava which resembles the tessellation of regular hexagons.

    Tessellation Patterns are a way to express creativeness. A tessellation is a repeating pattern of shapes covering a plane without any gaps or overlaps. Choosing a pattern with triangles that are black and white was a way to express a pattern. There are so many different ways to create a tessellation pattern and use of transformation. Normally, tessellations are created using polygons, this one was created using triangles.…
