Two drainage basins each cover 50 km\(^2\). Basin A is almost circular with an elongation ratio of 1.0, while Basin B is elongated with an elongation ratio of 2.5. Which basin is likely to produce the higher peak discharge for an identical storm, and why?

Answer Options

Correct Answer A. Basin A (the more circular basin) will have the higher peak discharge because its compact shape yields a shorter concentration time.
B. Basin B (the more elongated basin) will have the higher peak discharge because its shape causes a shorter concentration time.
C. Basin B (the more elongated basin) will have the higher peak discharge because its longer flow paths increase runoff concentration.
D. Basin A (the more circular basin) will have the higher peak discharge because its larger area collects more rainfall.
Correct Answer
A
Correct Option:
Basin A (the more circular basin) will have the higher peak discharge because its compact shape yields a shorter concentration time.
