The longitude of 82 ° 30’E is considered as the Standard Meridian of India. The time at the Standard Meridian is regarded as the time for the whole country and is called the Indian Standard Time or IST.

The cities of Lucknow, Raipur and Hyderabad lie to the western side of the Standard Meridian  of India. Some major state capitals closely lying to the  Eastern side of IST are Patna, Kolkata, Bhubaneswar, Ranchi etc.

The standard meridian is established in all the countries so that there’s an equal time in the whole country. In India, there is equal time across the country as per IST. However, there’s a difference of about 1 hour and 45 minutes between the original times of Dwarka in Gujarat and Dibrugarh in Assam.

Statement 1 is incorrect: According to the amount of water present in rivers throughout the year, rivers are divided into two categories: 

• Perennial rivers, which have water present throughout the entire year; and 
• Ephemeral rivers, which have seasonal water presence, with the majority of it occurring during the monsoon season.

Statement 2 is correct: A catchment is a region of land that gathers water during rainstorms and is frequently enclosed by hills. The water finds its way to streams as it travels across the terrain, eventually feeding the river. In periods of low rainfall, some of this water remains underground and gradually feeds the river.

Statement 3 is correct: An area that is drained by a river and all of its tributaries is known as a river drainage basin. Many diverse watersheds make up a river basin.

Statement 4 is correct: There is a drainage basin for each river. A watershed is the boundary line that separates one drainage basin from another. The catchments of large rivers are called river basins, while those of small rivulets and rills are often also referred to as watersheds. There is, however, a slight difference between a river basin and a watershed. Watersheds are small in area, while basins cover larger areas.
