Q6. (a) (b) Explain the following terms: Pearson distribution, Weibull distribution, Flood frequency, and Frequency curve. In developing IDF relationship for a rainfall station, 18 annual maximum one-hour rainfall depth is being compiled as shown in Table Q6. Estimate the probabilities and the recurrence intervals of all the rainfall values using Weibull equation. Weibull probability formula, P = m/(n+1) Table Q6: Maximum hourly rainfall data Year 1976 1977 1978 1979 1980 1981 Rain depth Year (cm) 2.90 3.28 8.18 3.02 2.77 3.51 1982 1983 1984 1991 1990 1989 Rain depth (cm) 2.78 3.12 3.83 3.12 3.07 3.06 Year 1985 1986 1987 1988 1989 1990 Rain depth (cm) 3.23 2.98 3.04 3.30 3.28 3.23
