WebSimilarly, the 500-year flood level is that gage height corresponding to the discharge extrapolated at RI = 500, which has a probability of being met or exceeded of 0.2 %. To determine the flood plain that will be inundated by a 100- or a 500-year flood, compare the topography of the area adjacent to the river to the predicted gage height. 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))) csula history https://goodnessmaker.com
