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
