Irrigation Engineering Main purpose of mean water training for rivers is To preserve the channel in good shape by efficient disposal of suspended and bed load To provide sufficient depth of water in navigable channels, during low water periods All of these Flood control To preserve the channel in good shape by efficient disposal of suspended and bed load To provide sufficient depth of water in navigable channels, during low water periods All of these Flood control 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 = (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) t = (h - 1)/(G - t) ANSWER DOWNLOAD EXAMIANS APP
