Indian National Centre for Ocean Information Services (INCOIS) and Indian Space Research Organisation (ISRO) have embarked on a project to continuously monitor and issue operational forecast alerts of rip currents.
- These are a strong flow of water running from a beach back to the Open Ocean, sea, or lake.
- These are one of the most well-known coastal hazards on beaches around the world.
- Formation
- They are formed by a beach topography.
- They can occur in areas with hard-bottom (rocky) or soft-bottom (sand or silt) beach topography.
- A beaches topography includes the area outside the water, such as dunes or marshes.
- Beach topography also includes the area within the water, like sandbars, piers, and reefs. Rip currents often form around these parts of a beach topography.
- They can form in a gap between sandbars, piers, or parts of a reef.
- Such underwater obstacles block waves from washing directly back to sea.
- The water from these waves, called feeder waves, runs along the shore until it finds an opening around the obstacle.
- Contrary to popular belief, a rip cannot pull a person down and hold him/her under the water.
- It simply carries floating objects, including people, out to just beyond the zone of the breaking waves.
Hence only statement 1 is correct.

Consider the following statements regarding the Rip Currents:1. These ...
Explanation:
Rip Currents:
Rip currents are powerful, narrow channels of fast-moving water that can be found along coastlines around the world. They are also known as rip tides or undertows.
Statement Analysis:
1. These are a strong flow of water running from a beach back to the open ocean:
- This statement is correct. Rip currents typically flow from the shore out to sea, carrying water that has piled up near the shore back into deeper water.
2. These occur in areas with hard-bottom beach topography only:
- This statement is incorrect. Rip currents can occur on any type of beach, regardless of the bottom topography. They are often found near jetties, piers, and groins, as well as in breaks in sandbars.
Therefore, the correct answer is option 'A' (1 only).
