Irrigation Engineering The peak of a 4 hour flood hydrograph is 240 m3/sec . If the rainfall excess is 80 mm and base flow which is constant is 40 m3/sec, then the peak of 4-hours unit hydrograph will be 35 m3/sec 30 m3/sec 25 m3/sec 20 m3/sec 35 m3/sec 30 m3/sec 25 m3/sec 20 m3/sec ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering If the risk of a flood occurring in the next 10 years is accepted to 10%, then the return period for design should be 1 – (0.9)°l0 1 + (0.9)010 1/(1-0.9°10) 1/(1+ 0.9010) 1 – (0.9)°l0 1 + (0.9)010 1/(1-0.9°10) 1/(1+ 0.9010) ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering According to Lacey, depth of scour in a river depends upon the straightness of the reach. If D is the depth of scour in regime flow in a right angled bend, it is 2.00 D 1.75 D 1.50 D 1.25 D 2.00 D 1.75 D 1.50 D 1.25 D 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)1/3 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 D = 0.47 (Q/f)1/2 D = 0.47 (Q/f) D = 0.47 (Q/f)2/3 ANSWER DOWNLOAD EXAMIANS APP
