    About Ravine:

    • A ravine is a landform narrower than a canyon and is often the product of stream cutting erosion.
    • Ravines are typically classified as larger in scale than gullies, although smaller than valleys.
    • Ravines may or may not have active streams flowing along the downslope channel which originally formed them.
    • Some other terms for Ravine are: – Cleuch, Dell, Gill or Ghyll, Glen, Gorge.

    About Chambal River:

    • The Chambal River is a tributary of the Yamuna River in central India, and thus forms part of the greater Gangetic drainage system.
    • The river flows north-northeast through Madhya Pradesh, running for a time through Rajasthan, then forming the boundary between Rajasthan and Madhya Pradesh before turning southeast to join the Yamuna in Uttar Pradesh state.
    • The Chambal and its tributaries drain the Malwa region of northwestern Madhya Pradesh, while its tributary, the Banas, which rises in the Aravalli Range, drains southeastern Rajasthan.
    • The Chambal River is considered pollution free, and hosts an amazing riverine faunal assemblage including 2 species of crocodilians – the mugger and gharial, 8 species of freshwater turtles, smooth-coated otters, gangetic river dolphins, skimmers, black-bellied terns, sarus cranes and black-necked storks, amongst
      others.
