(b) Plot the flow duration curve (FDC) for daily runoff of the stream. In plotting the FDC, use the empirical Weibull cumulative probability formulation we discussed in the class and … WebStep 2. Find the appropriate values for each variable. In the Rational Method equation, “C” is the runoff coefficient, meaning it is your unknown. “Q” is the value for the peak rate of …
Web20 jul. 2024 · To begin, let’s derive the basic precipitation-runoff relationship. 1. Development of the basic equation. The formulation of the SCS-CN method begins with the water budget expression, stated in depth units, That is, rainfall ( P) is runoff ( Q) plus losses ( F ). We also require the potential maximum retention (or infiltration), S. WebStep 11 – Calculation of the 10-year interval peak flow (Q 10) That flow is calculated using the following formula: Q 10 (m³/s) = (C p F i I A b F L) /360. where: C p = Weighted …
