Describe briefly the principle of the Rational method and the limitation of this method for runoff estimation. A sub-catchment of area 0.1km2 is built on gently sloping land. The average slope of the land is 0.001. The length of the longest natural flow path L is 276.3m. The flow time tf in the drainage system is 3min. Determine the 50yr design discharge for the subdivision using the rational method, given that the average runoff coefficient of the subdivision is C=0.7....

The centered average of a list of numbers is the arithmetic mean of all the numbers...

The centered average of a list of numbers is the arithmetic mean of all the numbers in the list, except for the smallest and largest values. If the list has multiple copies of the smallest or largest values, only one copy is ignored when calculating the mean. For example, given the list [1, 1, 5, 3 5, 10, 8, 7], one 1 and 10 are ignored, and the centered average is the mean of the remaining values; that is, 5.2....

Use the Rational Zero Test to list all possible rational zeros of f. Test each possible rational zero to determine whether it is an actual zero of f. (Enter your answers as a comma-separated list. If there are no rational zeros, enter NONE.) f(x) = x4 + 2x3 + 4x2 + 3x − 10 possible rational zeroes x= actual rational zeroes x=

1. Use cardinality to show that between any two rational numbers there is an irrational number. Hint: Given rational numbers a < b, first show that [a,b] is uncountable. Now use a proof by contradiction. 2. Let X be any set. Show that X and P(X) do not have the same cardinality. Here P(X) denote the power set of X. Hint: Use a proof by contradiction. If a bijection:X→P(X)exists, use it to construct a set Y ∈P(X) for which Y...
