Introduction-

• The word Punjab is made of two words Punj (Five)+ Aab (Water) i.e. land of five rivers.
• It is named so because of the five rivers flowing through this land and these five rivers of Punjab are Sutlej, Beas, Ravi, Chenab and Jhelum.
• Historically, Punjab was the name of the region containing today's states of Punjab (Pakistan), Punjab (India), Haryana, Himachal Pradesh and Delhi.
• The rivers flowing through this region are an important geographical feature of this land, thus made this region popular with the name 'land of five rivers' or Punjab'.
• As of today, only two rivers Sutlej and Beas flow through Punjab state in India. The third river Ravi flows partially in Punjab, mainly along the international boundary of India and Pakistan and then enters Pakistan.
• The other two rivers Chenab and Jhelum flow in the Punjab state in Pakistan. All these five rivers are tributaries of Indus River. All these five rivers finally merge into Indus River directly or indirectly and the Indus then terminates into Arabian Sea near Karachi city in Pakistan.

There are 2 types of rivers in Punjab which are following-
1) Perennial (always flooded with water)- Satluj, Beas and Ravi
2) Seasonal or Ephemeral- Ghaggar
