The flow of water through well-defined channels is known as ‘drainage’ and the network of such channels is called a ‘drainage system’.
Indian drainage system consists of a large number of small and big rivers. It is the outcome of the evolutionary process of the three major physiographic units and the nature and characteristics of precipitation.
On the basis of the mode of origin, nature and characteristics, the Indian drainage may also be classified into:
The Himalayan drainage consists of several river systems but the following are the major river systems
Three major geological events in the distant past have shaped the present drainage systems of Peninsular India:
Variability in Water Distribution: Perennial rivers flow year-round, while non-perennial rivers lack water in dry seasons. Excess water during the rainy season often causes floods.
Management Issues: Problems stem more from poor water management than from water scarcity, affecting how floods and droughts are addressed simultaneously.
Inter-Basin Water Transfer: Suggests transferring water from surplus basins to deficit ones and explores existing schemes for inter-basin linkage.
Challenges of River Linking: Highlights logistical challenges, including terrain unevenness, and questions the availability of surplus water for consistent transfer.
Pollution and Usage Problems: Discusses river water pollution from urban, industrial, and ritual sources, and ranks issues like water quantity, pollution, silt, and uneven flow.
Clean-up Initiatives: References major efforts like the Ganga Action Plan and suggests organizing a debate and creating a write-up on river cleanliness initiatives.
