What is the adjusted runoff coefficient for QD?

• A. 0.6666
• B. 0.2
• C. 0.538
• D. 0.95

Answer: (C)

The adjusted runoff coefficient is a crucial parameter in hydrology as it quantifies the fraction of precipitation that becomes surface runoff. It varies based on land use, soil type, and other environmental factors. In the context of the question, the value of 0.538 suggests a calculation that accounts for specific site conditions, including the infiltration capacity of the soil and the type of land cover. A coefficient in this range often indicates that the area experiences some degree of absorption, with a significant portion of precipitation infiltrating into the soil, while still allowing for a measurable runoff based on the area's characteristics. Values like 0.6666 and 0.95 would represent higher runoff coefficients, indicating less infiltration and more runoff, suggesting poor infiltration conditions. On the other hand, a coefficient of 0.2 would suggest that only a small fraction of precipitation is turning into runoff, which would not be typical in many situations where the hydrological cycle is considered. The lower values indicate different hydrological characteristics that may not align with the expected runoff trends given the usual conditions present in many catchment areas. Thus, the selection of 0.538 reflects a balanced view of runoff versus infiltration given the variables at play in this particular scenario.
