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)2/3 D = 0.47 (Q/f) D = 0.47 (Q/f)1/3 D = 0.47 (Q/f)1/2 D = 0.47 (Q/f)2/3 D = 0.47 (Q/f) ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering The total capacity of a reservoir is 25 million cubic metres and dead storage is 5 million cubic metres. If the average volume of sediment deposition is 0.10 million cubic metre per year, then the usefulness of the reservoir will start reducing after 200 years 50 years 250 years 150 years 200 years 50 years 250 years 150 years ANSWER DOWNLOAD EXAMIANS APP
