Different Drainage Patterns
- Dendritic: Branches formed a drainage system called dendritic drainage. For instance, gutters in the northern plains form drainage systems. Example: The Mississippi River system in the United States, Ganga River system.
- Radial: Radial drainage occurs when gutters come from a hill and run in all directions simultaneously. The Amarkantak range, for example, forms gutters. Example: Narmada River in central India.
- Trellis: A kiosk pattern is one that has the primary feeders parallel to each other and the secondary feeders at right angles to them. Example: rivers in the Deccan Plateau, such as the Krishna and Godavari rivers
- Centripetal: In a lake or depression, centripetal discharge occurs when the gutters discharge their water from all directions at the same time. Example: River Sabarmati and the Luni.
- Rectangular pattern: This pattern features a network of rivers and streams that flow in a rectilinear or right-angled pattern. It occurs in areas with highly jointed or faulted bedrock. Example: The Chambal River and its tributaries.
- Deranged pattern: This pattern lacks a consistent or organized structure, typically due to disruptive factors such as glaciation or tectonic activity. It is common in regions with recent geological disturbances. Example: The region of Kerala in southern India.
- Parallel pattern: In this pattern, rivers flow roughly parallel to each other without significant tributaries. It commonly occurs in steep, narrow valleys with uniform rock structures. Example: The Tapti River in western India.
Which is the largest drainage system in India?
The largest drainage system in the context of India is Ganga. In India, large and small gutters make up the drainage system. Rush is the result of the evolution of the three major physiographic units, as well as the characteristics and nature of rushing. The Himalayan drainage system includes the Ganga, the Indus, and the Brahmaputra swash basins. The peninsular table is drained by Narmada, Tapi, Kaveri, Godavari, Mahanadi, and Krishna.
India’s 90 percent of total face water is drained into the Bay of Bengal and the rest is in the Arabian Sea. The ridge of water extending through the Western Ghats, Aravalli, and Yamuna Sutlej Peak separates drainage systems flowing into the Arabian Sea and the Bay of Bengal. The Indian drainage system consists of a large number of small and big gutters. It’s the outgrowth of the evolutionary process of the three major physiographic units and the nature and characteristics of rush.
