Question

What is the difference between perennial and seasonal rivers and lakes?

Answer 1

Hint:: Perennial rivers are those rivers in which the water flows throughout the year, helps in underground water. But seasonal rivers are those rivers that flow at a particular time that is in the rainy season.

Complete step by step answer:
Perennial stream: perennial is a stream or river which flows constantly throughout a year from parts of its stream and in normal rainfall. if the water is not coming prolonged or there is a case of drought so perennial rivers continuously flow and provide groundwater.
 For example, disruption of the stream which is artificially made, or the stream selection associated with activity in hydropower installations, shall not affect the measurement. Perennial streams didn't consist of stagnant water for the wetland, reservoir, that occur all around the period. Seasonal river: As the name suggests 'seasonal'. Something which comes during a particular season. so these are the rivers which flowed during the particular time or season that is in the rainy season. Once the rainfall stops during the season. Things started happening oppositely. That means there is a drought everywhere. the river is continued to flow as, water moves down in the river till these little streams dry up and the river gets smaller and narrower until there is only a long stretch of river til it dries out completely .when time pass, the rainy season again started til there is a flowing of the river for another few months and the cycle goes continues., year after year and resulted from a seasonal river.

Note: Day by day perennial rivers convert into seasonal rivers with fragment flows. This creates a disturbance. especially for rivers of India like Gomti, Ramganga, Betwa, Chambal, and many are there.
