Assume a one$-$dimensional rectangular soil column having a depth of $50$ m and a constant

width of $10$ m$,$ n $=0\mathrm{.}25,24$ m$/$hr$,$ and the length of the column is $1000$ m$.$ Flow rate Q $=600$

m$3/$hr and is supplied at the left boundary. a$)$ Compute time take to travel for a particle released

in the left to reach the right boundary $($distance of $1000$ m$)?$ b$)$ How will the transport time

change, if you doubled the conductivity? c$)$ How will the transport time change if you doubled

the porosity? d$)$ Find the total head loss across the column under these two soil conditions? e$)$ If

the head in the inlet boundary $($left boundary$)$ is $125$ m$,$ what is the value of the head must be at

$250$ away from the inlet point under the two hydraulic conductivity conditions? f$)$ Will the value

of head at $250$ m away from the inlet point change if we only doubled the porosity? Ans for $($a$)$

should be about $7$ to $10$ days.
