Explain the concept of a drainage basin as described in the text.

A drainage basin is the area drained by a single river system. It is formed by small streams flowing from different directions that come together to form the main river, which ultimately drains into a large water body such as a lake, sea, or ocean. Signup and view all the answers

What is a water divide and how does it relate to drainage basins?

A water divide is an elevated area, such as a mountain or upland, that separates two drainage basins. It acts as a boundary between the areas drained by different river systems. Signup and view all the answers

Differentiate between the Himalayan rivers and the Peninsular rivers mentioned in the text.

The Himalayan rivers are described as perennial, meaning they have water throughout the year. On the other hand, the Peninsular rivers may not have water year-round and are different from the Himalayan rivers in many ways. Signup and view all the answers

What are the two major groups into which the Indian rivers are divided?

The Indian rivers are divided into two major groups: the Himalayan rivers and the Peninsular rivers, based on their origins from the Himalayan and Peninsular physiographic regions. Signup and view all the answers

How do small streams contribute to the formation of a drainage basin?

Small streams flowing from different directions come together to form the main river in a drainage basin. These streams ultimately drain into a large water body, such as a lake, sea, or ocean. Signup and view all the answers

Study Notes

Drainage System Overview

Drainage refers to the river system within a specific area.
Small streams converge to form a main river, which eventually flows into larger bodies of water (lakes, seas, oceans).
The area served by a single river system is known as a drainage basin.

Water Divide

Elevated terrains, like mountains or uplands, demarcate two distinct drainage basins.
This elevated region is termed a water divide, which plays a crucial role in directing water flow and defining watershed boundaries.

Types of Rivers in India

Indian rivers are categorized into two principal groups based on their origin:
- Himalayan Rivers
- Peninsular Rivers
Himalayan rivers typically maintain a perennial flow, meaning they have water year-round, a result of consistent snowfall and glacial melt.

Differences Between River Types

Himalayan and Peninsular rivers exhibit notable differences in characteristics and behavior due to their distinct geographical origins.
