Consider the following data.

$h_A=200m$

$h_B=198m$

$L_{AB}=200m$

$k=0\mathrm{.}01\frac{(cm)}{(s)}$

$n=0\mathrm{.}25$

$k_d=0\mathrm{.}2\frac{c{m}^3}{(g)}$

${}_b=2\mathrm{.}5\frac{(g)}{c{m}^3}$

Answer the following questions.

What is the direction of flow?

What is the hydraulic gradient?

What is the specific discharge?

What is the pore water velocity?

What is the retardation coefficient?

$-$What is the contaminant transport velocity?
