Answer to Question 1

Floods are rated statistically for the probability that a flood will occur sometime during a given interval. This is based on historical trands. For instance, a 100-year flood has a probability of occurring 1 time in 100 years or a likelihood of 1 in any given year. A 50-year flood has a probability of occurring 1 time in 50 years, 2 times in 100 years, or a likelihood of 2 in any given year. A 25-year flood is one that has a probability of occurring 1 time in 25 years or 4 times in 100 years, or a likelihood of 4 in any given year. A 10-year flood has a probability of occurring 1 time in 10 years, 10 times in 100 years, or a likelihood of 10 in any given year. etc.

Answer to Question 2

Hundreds of millions of individuals live on floodplains and deltas. The problem is particularly acute in developing nations. For instance, more than 3/4ths of the land in Bangladesh is in floodplains.
Answers on recent examples of flood hazards will vary, especially if students use outside materials. The book mentions the August 2010 flooding of the Indus and its tributaries due to heavy monsoon rains.
