Assertion: Due to the inherent nature of various parameters involved in the process, the yield from a catchment is a random variable.
- The yield from a catchment is influenced by various natural processes, including precipitation, infiltration, and evapotranspiration.
- These processes are subject to variability and uncertainties due to factors such as weather patterns, soil characteristics, and vegetation cover.
- As a result, the yield from a catchment cannot be precisely predicted and is considered a random variable.
- True: The assertion is correct because the inherent variability in the influencing parameters makes the catchment yield a random variable.
Reason: The yield from a catchment is the end-product of various processes such as precipitation, infiltration, and evapotranspiration operating on the catchment.
- The yield from a catchment is indeed the result of multiple hydrological processes like precipitation (which provides water input), infiltration (which affects how much water enters the soil), and evapotranspiration (which involves the loss of water through evaporation and plant transpiration).
- These processes collectively determine the amount of water that ultimately flows out of the catchment.
- True: The reason is correct because it accurately describes the processes contributing to the catchment yield.
Since the assertion correctly identifies the nature of catchment yield as a random variable due to variability in influencing parameters, and the reason accurately describes the processes affecting the yield, it is clear that the reason provides a correct explanation for the assertion.
