Modeling Background
Early in my career as a groundwater hydrologist, my computing
skills facilitated some pioneering simulation work, mainly in fracture
system flow and transport. With the advent of computer specialists, I
have relinquished the hands-on work to others, while emphasizing my broad
experience as a reviewer and analyst. While I have the necessary knowledge
of the capabilities and limitations of modeling methods, much that I contribute
is by critiquing assumptions, underlying geology, boundary conditions
and material properties.
