Description 1253-1259
In this study, a two-dimensional numerical model of the Gulf of Khambat has been implemented based on
the Delft3D code to study the tidal propagation in the basin. The model has
been calibrated and validated versus tidal measurements. Moreover, an
analytical model for tidal propagation in converging estuary has been
implemented based on the analytical work of Van Rijn (2011a). The two models
show a good agreement, also with respect to observations. Moreover, the use of
an analytical model with very low computational time, in support to a more
sophisticated but computational time consuming numerical model, allows for an
easy understanding of the different geometrical parameters (e.g. convergence
length, water depth) and physical processes (e.g. damping due to bottom
friction, tidal shoaling due to funnelling shape, tidal reflection) affecting
the system and for an interpretation of the results of the more complex Delft3D
numerical model. The effects of external changes on the physical system (e.g.
impact of sea level rise) can also be easily accessed by means of a simple
analytical model.
