CLASS: IX - GEOGRAPHY

CHAPTER:3 : DRAINAGE
 
Drainage means the river system in a particular area. A river system consists of the total area covered by the tributaries and other water bodies that join the main river.
 
The largest river basin in the world is the Amazon river basin. Drainage systems in India can broadly be categorized as Himalayan rivers and Peninsular rivers. The Himalayan rivers are fed by the snow melting from the mighty Himalayas and also seasonal rains, and hence these are perennial rivers. The four main drainage patterns are: Dendritic Drainage, Rectangular Drainage, Trellis Drainage and Radial Drainage.
 
Lakes are important for various reasons, like regulating the flow of river water, storage of water during the dry seasons, to maintaining the eco-system, and also the generation of hydroelectric power. The different types of lakes in India are freshwater lakes and salt water lakes. The Wular Lake in Jammu and Kashmir is the largest freshwater lake in India.
 
The Chilika Lake in Orissa is the largest brackish water lake in India.
 
Rivers are considered the most basic natural resources required for human settlement. The primary reason is that we depend on rivers for fresh drinking water and water for irrigation. River water is also used for generating hydroelectric power.
 
The growing demand for water in agriculture, industry and domestic use is affecting the quality of water. There has been some government action to counter this by launching activities such as the National River Conservation Plan (NRCP) and the Ganga Action Plan (GAP) introduced in 1985.
