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 1.75 D 1.25 D 2.00 D 1.50 D 1.75 D 1.25 D 2.00 D 1.50 D ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering The main function of a divide wall is to separate the undersluices from weir proper provide smooth flow at sufficiently low velocity control the silt entry in the canal prevent river floods from entering the canal separate the undersluices from weir proper provide smooth flow at sufficiently low velocity control the silt entry in the canal prevent river floods from entering the canal ANSWER DOWNLOAD EXAMIANS APP

Irrigation Engineering The discharge passing over an ogee spillway is given by (where, L is effective length of spillway crest and H is the total head over the spillway crest including velocity head.) CLH5/2 CLH1/2 CLH3/2 CHL3/2 CLH5/2 CLH1/2 CLH3/2 CHL3/2 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)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 D = 0.47 (Q/f)1/2 D = 0.47 (Q/f) ANSWER DOWNLOAD EXAMIANS APP
