Macroscale diffusion-limited sorption modeling -- a preliminary modeling exercise for a Dover AFB site. Master`s thesis
A modification was made to the USGS SUTRA code which allowed the simulation of macro scale diffusion effects from specific layers. The code was applied to a conceptual site developed from a field site at Dover AFB, DL Simulations were done to compare the modified code to the unmodified code which clearly showed the modified code as a closer representation of reality. Simulations were also done to study the effects of pulsed and continuous pumping within the time frame of a field experiment at Dover. These simulations indicated that the diffusion time scale was too long to be studied within the 180 days of the field study. Further investigation over a longer period of time provided the opportunity to study rebound effects due to macroscale diffusion. These simulations confirm the effectiveness of the macroscale model in representing actual physical processes.
