A $6\mathrm{.}2-$m high concrete gravity wall, $3\mathrm{.}8$ m wide at the base exerts a pressure of $220$ kPa at toe and $250$ kPa at the heel during the dry seasons. The front wall is vertical while the inclination of the back wall is $71$ supporting a backfill non$-$cohesive soil with a surface slope of $12,$ shear strength parameters of $($c $=0$ kPa and $=12),$ bulk and saturated unit weights of $17$ and $21$ kN$/$m$^3$ respectively. During dry condition the water table is quite below the wall base, but during the flooding the water rises to $0\mathrm{.}7$ m above the wall base on both sides of the wall. The friction between wall and soil is $11.$ By considering $1-$m length of the wall, check the suitability of the design during dry and flood conditions. $[$Hint: account for uplift at the base of the wall, you may also ignore lateral hydrostatic pressure since their effect cancels out on both sides of the wall.$]$
