Tutorial 04
1.
An analysis of flood data showed that the probability of a flood
peak exceeding 3000 m3/s on Kiami river in any year was 0.02. During
a 10 year period 2 such peaks occurred.
If the original estimate of the probability of this exceedance was correct, what
is the probability of getting 2 such exceedance in 10 years?
2.
The analysis of daily extreme runoff data using Gumbel
distribution shows that;
Pr [ X ≤ 100 m3/s ] = 0.90
Pr [ X ≤ 130 m3/s ] = 0.98
Compute the daily runoff for a return period of 100 years.
