Problem $1$:

Groundwater is $15ft$ below as indicated with the GW symbol:

Oft

Medium Dense Sand

$g_{\text{m}\text{o}\text{i}\text{s}\text{t}}=124pcf$

$g_{\text{s}\text{a}\text{t}}=138pcf$

$15ft$

$15ft$

Clay

$g_{\text{s}\text{a}\text{t}}=130pcf$

$C_c=0\mathrm{.}45$

$C_s=0\mathrm{.}05$

$e_0=0\mathrm{.}86$

$25ft$

Given the stratification provided above find

a$.u,s,s^{\text{'}}$ at $10ft$ and $25ft$
