  • Prompt

    Test students' ability to apply the Rational Method (Q = C · i · A) to estimate peak stormwater runoff for a mixed land‑use urban catchment: select appropriate runoff coefficients from a provided land‑use table, compute an area‑weighted composite C, perform necessary unit conversions (area and rainfall intensity), calculate peak discharge for a given rainfall intensity and area, and briefly explain key assumptions and limitations of the method.
