Group $(4)$

Problem $(1)$

For the hydraulic structure shown below:

$1-$ Using Lane's weighted creep theory, find the minimum depth $($ d $)$ of the cutoff in if $C=3$

$2-$ Using Bligh creep theory, find the minimum depth $($d$)$ of the cutoff in if $C=9$

$3-$ Calculate the uplift pressure at Point A using Lane method and assuming $d=10m$

$4-$ Calculate floor thickness at Point A

$5-$ If the floor thickness is $2\mathrm{.}5$ m at A$,$ is the structure safe against uplift?
