1. Rozendaal, Marco (author). An Idealised Morphodynamic Model of a Tidal Inlet and the Adjacent Sea.

Degree: 2019, Delft University of Technology

Tidal inlet systems are often highly valuable and sometimes even unique ecosystems. However, field measurements show that tidal inlet systems are sensitive to changing exogenous conditions, such as rising sea levels. This thesis aims to investigate to what extent the adjacent sea influences the stability and equilibrium state of the tidal inlet. A one-dimensional idealised model is used to model the interaction between the sea and the inlet. The water motion is forced by the tide and the inlet is assumed to be narrow and short. At equilibrium, an increasingly sloping bottom is found in the sea and a constantly sloping bottom in the inlet. This equilibrium bottom profile seems to be in reasonable agreement with observations. The sea-inlet bottom profile is less stable than the inlet bottom profile, nevertheless, the sea-inlet bottom profile is still asymptotically linear stable. Moreover, the results in this thesis suggest that for one-dimensional idealised models consisting solely of a tidal inlet, the correct seaward boundary condition is a properly chosen fixed entrance depth. For a two-dimensional semi-infinite sea, it is shown that a Perfectly Matched Layer is a convenient method to incorporate the Sommerfeld radiation condition and that the narrow tidal inlet cannot be modelled as a point source forcing in the two-dimensional sea domain.
