The maximum annual flows of a river can be modeled by the Gumbel law. The average of flow rates calculated with 57 years of observations is 8 m3/s and the standard deviation is 2.4 m3/s. The region is flooded with damage when the flow exceeds 10 m3/s.

a) What is the return period of the 10 m3/s flow.

b) What is the throughput for a 100 year return period.

c) Determine the 95% confidence interval around the flow calculated in b).

The flow in a river can be modeled as a log-normal distribution. From the data, it was estimated that, the probability that the flow exceeds 1100 cfs is 50% and the probability that it exceeds 100 cfs is 90%. Let X denote the flow in cfs in the river. Flood conditions occur when flow is 5000 cfs or above. To compute the percentage of time flood conditions occur for this river, we have to find, P(X≥5000)=1-P(Z<a). What is the value...

River Kisigo flows through an area next to a medium sized city into river Rufiji. During recent years, annual floods have damaged homes in its vicinity at an increased' rate. Average annual flood damages have been estimated to be Tshs 180M at present and are expected to increase by Tshs 12M each year. To contain excessive runoff two proposals have been made. One is to do some channel improvement (CI). Another proposal is to build a storage dam and small...

The proton is not truly a point particle, but can be modeled as a sphere of radius approx 1 fm. This is an approximation. Calculate the probability that the electron in the ground state of hydrogen will be found within 1.00000 fm of the center of the proton in the following two ways. Talk about the differences or lack of differences between the two results. a.) Integrate the radial probability density over the appropriate range of radii. b.) Multiply the...
