Dispersion Modeling Simplified – Bits and Pieces
When we say something is complicated, what does that really mean? In grad school, I had a final that had just two problems. The first problem was, from basic principles, derive the full (no simplifications) Navier-Stokes equations. The second problem was to derive the full vorticity equations and identify what each term means. In high…

NK Tools for Model Input
A while back, I posted the article Connect Your Modeling Database to Your GIS, preaching the benefits of using a database-centric approach to dispersion modeling. The main point of the article was one thing (a database) is easier to manage than dozens or hundreds of free-floating files. If you are reviewing someone else’s modeling project,…
