    Study Notes

    Drainage Systems

    • The flow of water through well-defined channels is called a drainage system.
    • Flooding is common in areas with ill-defined or choked channels.

    Drainage Patterns

    • The drainage pattern of an area is determined by its geological structure.
    • The term used to describe the network of well-defined channels through which water flows is a drainage system.
    • Rivers originating from the Himalayas and the Western Ghats flow towards the east due to the slope of the land.

    Himalayan Drainage System

    • The Himalayan drainage system includes rivers like the Indus, Ganga, and Brahmaputra.
    • These rivers form depositional features like deltas and floodplains as they enter the plains.
    • Rivers in the Himalayan reaches form deep gorges and valleys.

    River Basins

    • The term used to describe the area drained by a river and its tributaries is a river basin.
    • The Himalayan drainage system includes major river basins like the Indus, Ganga, and Brahmaputra.
    • The Peninsular drainage system includes river basins like the Godavari, Krishna, and Narmada.

    Rivers of India

    • The Indus River originates in Tibet and receives the Kabul river in Pakistan.
    • The Ganga River rises from the Gangotri glacier and meets the Alaknanda at Devprayag.
    • The Brahmaputra River originates in Tibet and is known as the Jamuna in Bangladesh.
    • The Peninsular drainage system includes rivers like the Narmada, Tapi, Godavari, and Krishna.
    • The Western Ghats act as a water divide between major Peninsular rivers discharging water into the Arabian Sea and the Bay of Bengal.

    Characteristics of Rivers

    • Himalayan rivers have a flow regime controlled by melting of snow and ice.
    • Peninsular rivers have a flow regime controlled by rainfall.
    • Rivers in India have a varying flow regime depending on the season.
    • The nature of flow for Himalayan rivers is perennial.
    • The discharge of a river is the volume of water flowing through it.

    Conservation

    • 'Namami Devi Narmade' is a conservation mission for the Narmada river.
    • 'Namami Gange Programme' aims at the conservation and rejuvenation of the Ganga river.

    Geological Factors

    • Geological factors like the slope of the land and the geological structure of an area contribute to the drainage pattern of an area.
    • The primary purpose of a drainage system is to drain excess water from the land.
