Karnataka - Rivers and River Systems

Introduction

Understanding the rivers and river systems of Karnataka is crucial for exams like Karnataka PSC, SSC CGL, and RRB NTPC, as questions on geography and natural resources of the state are frequently asked. This pattern tests knowledge of major rivers, their tributaries, and the role they play in Karnataka's ecology and economy.

Pattern: Karnataka - Rivers and River Systems

Pattern

This pattern tests knowledge of the major rivers flowing through Karnataka, their tributaries, and associated river basins.

Key Concept:

Karnataka is drained mainly by three major river systems: the Krishna, the Cauvery, and the Godavari, along with several west-flowing rivers draining into the Arabian Sea.

Important Points:

  • Krishna River = Originates in Mahabaleshwar (Maharashtra), flows through northern Karnataka, important tributaries include Bhima and Tungabhadra.
  • Cauvery River = Originates in Talakaveri, Kodagu district, flows southeast through Karnataka and Tamil Nadu.
  • West-flowing rivers = Include Sharavathi, Kali, and Netravati, which drain into the Arabian Sea.

Related Topics:

  • Karnataka's irrigation projects
  • River basins and water resources management
