1. An extra credit problem (details in handout) Using maximum discharge data from Dry Creek, Louisiana for the past 20 years, estimate flood frequency and the annual probability of occurrence for floods of a given discharge. The data above are taken from Stephen Nelson’s (Tulane University) Geology 204, Natural Disasters class (see http://www.tulane.edu/~sanelson/geol204/hmwk5_00.htm).

3. Nelson asks us to consider the following: Someone has offered to sell you a 4-bedroom 2-story house with a 2 car garage and swimming pool on a 1 acre lot on a relatively flat piece of ground on the banks of Dry Creek for what seems like a reasonable price of $50,000. The last time the house was flooded it cost $40,000 to repair the flood damage. How often has the house been flooded in the last 20 years? What is the probability that the house will be flooded in the first year that you own it? Would you still consider buying the house? Why or why not?
