    Do you know the difference between Peninsular River regime and the Himalayan River regime

    The climatic condition of any place or region controlled the flow of the river system. The River Regime is the pattern of the seasonal flow of water in any river. In other words, the geographical pattern of rivers like width, depth, slope, distribution, and its flow and deposition characters all together can be considered as river regimes. Here, we are giving brief note which will be helpful for understanding the differences between Peninsular River regimes and the Himalayan River regimes.

    Difference between Peninsular River regime and the Himalayan River regime

    Basis of differences

    Reason

    Origin

    The Peninsular rivers rise at much lower heights in the Western Ghats whereas the Himalayan river originates at high elevations.

    Source

    The Peninsular rivers are non-perennial which means they receive water from glacier and rainfall whereas Himalayan rivers are perennial which means they are seasonal-dependent on monsoon.

    Catchment Area

     

    The Peninsular river have narrow catchment area whereas the Himalayan rivers have large catchment area. Larger catchment area ensures maximum flow of water.

    Variations

    The Peninsular rivers have huge variations due to uneven rainfall in the Plateau region whereas all the Himalayan rivers maintain a sizeable flow.

    Gradual increase/decrease in flow

    The Himalayan rivers has a minimum flow during Jan-June and maximum flow during August /September and gradual steady fall afterwards, whereas the Peninsular rivers has very low flow from January-July and a sharp rise in August and again a sudden fall in October.

    Supply of ground water

    The Peninsular river flows from the rocks of peninsular region which are hard and impermeable, where supply of ground water is limited whereas Himalayan rivers pass through plains whose alluvial soils act as a huge reservoir of ground water.

    Above write-up briefly explains the variability of river water discharge throughout the course of a year in response to precipitation, temperature, evapotranspiration, and drainage basin characteristics.
