Isolating T value
The probability R called risk that an exceedance occurs at least once in n successive years.
R = 1 - (1-1/T)^n
T= Return period
EXAMPLE: What return period must a hydrologist use in designing a critical spillway to accept only a 10% risk that flooding will occur in the next 5 years?
0.10 = 1 - (1-1/T)^5
T=48.1 years
HOW? Show me the steps to isolate T
