WebEq 3. For example, the probability that the maximum discharge will equal or exceed 50000 m 3 /s in any year is approximately p= 1/t= 1/5.1= 0.195 (19.5%) Suppose a certain flood (F) has a probability of occurrence of 10% - meaning a probability of 10% that this flood level will be reached or exceeded. Webvided to illustrate the methods. Transfer equations, risk, and low-flow methods are also addressed.
