Consider the following statements : 1. The Sharavati river creates Jog Falls. 2. The Brahmani river is formed by the confluence of the Kosi and Sankh rivers. 3. The Tamraparni is a river of Tirunelveli district of Tamil Nadu. How many of the above statements is/are correct?

Statement 1 is correct as the Sharavati river, originating in the Shimoga district of Karnataka, creates the famous Jog Falls (also known as Gersoppa Falls) [1][3]. Statement 2 is incorrect; the Brahmani river is formed by the confluence of the South Koel and Sankh rivers at Rourkela, Odisha, not the Kosi and Sankh [2]. Statement 3 is correct; the Tamraparni (or Thamirabarani) is a perennial river that flows through the Tirunelveli and Thoothukudi districts of Tamil Nadu. It is the shortest river in the state and originates in the Agastyarkoodam peak of the Pothigai hills. Since statements 1 and 3 are correct, while statement 2 is false, exactly two statements are correct.
