Figure $3.$ Changes in modeled drawdown $($at observation well$)$ versus time for each multiplier of horizontal hydraulic conductivity $($indicated by the different colored curves, where $1$ is the calibrated value$).$

Sensitivity to hydraulic conductivity:

A: Using Figure $3,$ discuss how the aquifer is sensitive to changes in the hydraulic conductivity, e$.$g$.$ what behavior $($in the time$-$drawdown curves$)$ do you note over the range of $Kx$ factors; and how does that behavior relate to what you know about hydraulic conductivity? $2$ pts

B: Now looking at the actual groundwater contours in Figure $4,$ what does the modeled behavior tell you about what is physically happening in the aquifer when $Kx$ is reduced to $10\%$ of its calibrated value $(0\mathrm{.}1)?1pt$

$C$ : Given your response to the previous question and referring to Figure $3,$ what happens in the aquifer when $Kx$ is reduced to $1\%$ of its calibrated value $(0\mathrm{.}01)?1pt$
