Flood peak flow
WebIn the chunk below, calculate the magnitude of a 1 in 100 chance, or 100 year flood using the following two formulas where p = non-exceedance probability and Tp = return period. These are just the equations used to calculate return period rearranged to calculate peak flow. p = 1 - (1 / Tp) peakflow = u - (alpha * ln(-ln(p))) WebApr 11, 2024 · Scheme 5: The downstream peak flow and maximum reservoir water level both equal that of the current operation rule.

WebThe term “design flood” is used to denote the maximum flood flow that could be passed without damage or serious threat to the stability of engineering structures. It is therefore, necessary to specify volume and period of flood flow that may flow down in conjunction with the peak flow. Thus, design flood hydrograph is also fully worked out ...

WebIf flow-frequency curves are available at multiple gauged sites, Equation 4-10 can be used to estimate the desired peak AEP flow from each site. Then, with judgment and knowledge of the watersheds, those estimates could be weighted to provide an estimate of the desired AEP flow at the ungauged location.
