As can be seen, smooth water depth along the gully and flood fringes is produced by the post process utility.<br> The default interpolation method is TIN. But "-idw_npt<number of points>" flag can be used to change the interpolation method to IDW and set the number of points used for IDW interpolation (default is 12).<br> [[File:Fig5 D sgs remap zoom.png\|700px]]<br> ~~Example:<br>~~ '''Figure 5 Remapped vs original water depth for 10/20m mesh SGS model.'''<br> ~~<li>~~ =1D Timestep=
