Which runoff coefficient would generate the most runoff?

• A. A. 0.95
• B. B. 0.50
• C. C. 0.30
• D. D. 0.15

Answer: (A)

The runoff coefficient is a crucial factor in hydrology that indicates the fraction of total rainfall that will become runoff. A higher runoff coefficient means that a larger portion of the precipitation is converted into runoff due to minimal absorption by the soil or other surfaces. In this context, a runoff coefficient of 0.95 implies that 95% of the rainfall will contribute to runoff. This is significantly higher than the other coefficients provided. For instance, coefficients of 0.50, 0.30, and 0.15 suggest that only 50%, 30%, and 15% of rainfall, respectively, turns into runoff, indicating much greater absorption, infiltration, or retention in those cases. Therefore, a runoff coefficient of 0.95 clearly indicates a scenario where very little water is absorbed, leading to the maximum amount of water being converted to runoff. This understanding is essential for effective water resource management and predicting flood events, as higher runoff can result in increased surface water flow and potential flooding downstream.
