Let me try to explain this:-
When two rivers meet, their waters may not mix immediately due to several reasons:
1. *Density differences*: If the two rivers have different temperatures, salinity, or sediment loads, their waters may have distinct densities. This can cause them to flow separately, with the denser water flowing underneath the less dense water.
2. *Velocity differences*: If the rivers have different flow rates or velocities, their waters may not mix readily. The faster-moving water may push the slower-moving water aside, creating a distinct boundary.
3. *Turbulence*: When two rivers meet, turbulence can occur, creating whirlpools or eddies. This turbulence can keep the waters from mixing immediately.
4. *Surface tension*: Water has a natural surface tension that can act as a barrier to mixing.
5. *Laminar flow*: If the rivers are flowing smoothly and steadily (laminar flow), their waters may not mix much, as the flow is layered and doesn't easily intermingle.
6. *Geomorphic constraints*: The shape and features of the riverbed and banks can influence the flow and mixing of the water.
