Describe the breakthrough curve you would expect for transport of a non-reactive solute injected as a finite pulse of duration 1 hour in a designed steady state Darcy flux of 0.5 m/hr arising from a head gradient of 0.1 in a soil column of porosity 0.25 and length 2 m, under the following conditions (ignore diffusion):
a. no dispersion
b. some dispersion but mostly advection After the experiment in part a, a fracture occurs, running the full length of the column from x=0 to x=2m, and the fracture conductivity is 1/10 of the conductivity of the column before the fracture occurs. You don't know about the fracture.
c. Describe the breakthrough curve resulting from your attempt to duplicate case a.
d. As in case c, but with a solute that undergoes equilibrium sorption reaction with bulk density = 1.5 g/cm3 and Kd of 1/3 cm3/g.
