$1($a$).$ The section of a Solid Gravity Dam built of concrete $($unit weight $\backslash (=24\backslash$mathrm$\{$kN$\}.\backslash$mathrm$\{$m$\}^\{-3\}\backslash ))$ is shown in the figure aside. A tailwater or D$/$S water depth is $6\mathrm{.}0$ m when the dam reservoir is at its maximum water level $($MWL$)$ at $86\mathrm{.}0$ m $.$ Taking the uplift pressure as equal to the hydrostatic $.$ pressure at either ends and considered to act over $\backslash (60\backslash \%\backslash )$ of the area of the base section, evaluate the $($i$)$ net uplift pressure force, $($ii$)$ hydrodynamic force $($as per Zanger's formula$)$ and $($iii$)$ earthquake forces $($horizontal and vertical$)$ acting on the dam section. The earthquake forces are equivalent to $0\mathrm{.}10$ g for horizontal forces and $0\mathrm{.}05$ g for vertical forces. $($take$,$ unit weight of water $\backslash (=10\backslash$mathrm$\{$kN$\}.\backslash$mathrm$\{$m$\}^\{-3\}\backslash ))$
