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 down stream of the crest wall, is given by the question-
1
\(t = \frac{{h }}{{G - 1}}\)
2
\(t = \frac{{h + 1}}{{G}}\)
3
\(t = \frac{{h - 1}}{{G + t}}\)
4
\(t = \frac{{h - 1}}{{G - t}}\)
