‘Watershed’ reflects the interaction of different features viz

  • A.Soil cover
  • B.Vegetation
  • C.Topography
  • D.All of the above

Answer: D

A watershed reflects the interaction of all three, so the answer is All of the above.

How a watershed behaves, how much rain runs off, how fast and with how much sediment, depends on its soil (texture, depth, infiltration), its vegetation (cover that intercepts rain and slows runoff) and its topography (slope, shape and drainage pattern), all acting on the same rainfall. Watershed management works on these together.

Choosing only one of the three leaves out the others, which act jointly.
