Tsunami Runup in Lagrangian Description
In general analyses of fluid dynamics, we fix attention on a particular point of space. On the other hand, in the Lagrangian point of view, we fix attention on a particular fluid particle and follow its motion. Independent variables are the initial position of the particle, (a, b, c), and the time, t. The position of the particle, \( (\hat x,\hat y,\hat z) \), and the pressure, \( \hat p \), are functions of (a, b, c, t).
