Irrigation Engineering When a canal flowing under pressure is carried below a natural drainage such that its F.S.L. does not touch the underside of the supporting structure, the structure so provided, is called Syphon-aqueduct Aqueduct Syphon Super passage Syphon-aqueduct Aqueduct Syphon Super passage ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering If the height of the hydraulic gradient line above the floor of thickness t is h and the specific gravity of the material of the floor is G, the minimum thickness t of the floor downstream of the crest-wall, is given by the equation t = (h - 1)/(G - t) t = (h + 1)/G t = (h - 1)/(G + t) t = (h + 1)/(G + t) t = (h - 1)/(G - t) t = (h + 1)/G t = (h - 1)/(G + t) t = (h + 1)/(G + t) ANSWER DOWNLOAD EXAMIANS APP
