  2. 2. The Himalayan rivers perform erosional activity in the upper courses. In the middle and lower courses these rivers form meanders, oxbow lakes and many other depositional features. A large number of peninsular rivers seasonal, as they are dependent on rainfall. THE FEATURES MADE BY RIVERS FEATURES MADE BY RIVERS
  3. 3. The streams within a drainage basin form certain patterns, depending on the slope of land as well as underlying rock structure and climatic conditions. These are dendritic, trellis, rectangular, and radial. THE DRAINAGE PATTERNS MADE BY RIVERS DRAINSAGE PATTERNS MADE BY RIVERS

  17. 17.  India has many lakes. They differ in size, and other factors.  Most lakes are permanent; some contain water only during rainy season.  A meandering river across a flood plain forms cut-offs that later develop into ox-bow lakes. Ex.: Chilika Lake, Pulicat Lake  Lakes in a region are sometimes seasonal. Ex.: Sambhar Lake THE INDIAN LAKES A VIEW FROM THE SHORES OF CHILIKA LAKE
  18. 18.  Most freshwater lakes are in the Himalayan region. They mostly form by glacier snowmelt. Ex.: Dal Lake, Wular Lake  Apart from natural lakes, the damming of rivers for hydro power generation has also led to the formation of Lakes.
