This was one of the early development projects I did at the job I was in at the time. We were basically asked to develop in an ArcGIS environment a tool that takes wind and current data from a weather station database and predict the movement (advection) of an oil spill over time.This is actually quite a simple task - the maths is pretty basic; you take a ratio of the wind and current vectors over a particular time step and this indicates the final motion vector of the spilled oil for the time step.
Two of us worked on this project and it took us 6 days from design to beta release.
The advection engine would later be used in combination with a "dispersion" model which I developed several years later.
