Ocean model performances are highly related to the vertical coordinate system implemented. We study geo-potential (or z-) coordinates and we focus on the numerical treatment of the moving free surface. Typically z-coordinate models are coded with a s

This is the SHYFEM model code - version 7_5_71 - with surface-adaptive z-coordinates. The code implements z-coordinate with insertion and removal of surface layers in order to to deal with an arbitrarily large tidal oscillation independently of the v

International audience; Despite the recognized impact of tidal bores on estuarine ecosystems, the large scale mechanism of bore formation in convergent alluvial estuaries is still under investigation. So far, field data exist only for a small number

We investigate the potential of the so-called "relocation" mesh adaptation in terms of resolution and efficiency for the simulation of free surface flows in the near shore region. Our work is developed in three main steps. First, we consider several
