Irrigation Engineering The maximum rainfall depth of 300 mm in 24 hours has a return period of 100 years. The probability of 24 hours rainfall equal to or greater than 300 mm occurring at least once in 10 years is given by 1 – (0.99)10 l-(0.9)100 (0.9)00 (0.99)10 1 – (0.99)10 l-(0.9)100 (0.9)00 (0.99)10 ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering The scour depth D of a river during flood, may be calculated from the Lacey's equation D = 0.47 (Q/f)1/2 D = 0.47 (Q/f) D = 0.47 (Q/f)2/3 D = 0.47 (Q/f)1/3 D = 0.47 (Q/f)1/2 D = 0.47 (Q/f) D = 0.47 (Q/f)2/3 D = 0.47 (Q/f)1/3 ANSWER DOWNLOAD EXAMIANS APP
