Gasoline spill in a major river.
The mayor of a large downstream city demands an estimate of hours for the spill
to get to reach supply plant intake.
Emergency responders measure the speed of the leading edge of the spill, effectively
focusing on one particle of fluid.
Environmental engineers employ a computer model which simulates the velocity
field for any stage of the river, and for all locations (including steep narrow canyon
sections with fast velocities, and an extremely wide reach with slow velocities).
To compare these two mathematical approaches, which statement is most correct?
a. The responders have an Eulerian approach, and the engineers have a Lagrangian
one
b. The responders have a Lagrangian approach, and the engineers have an Eulerian
one.
