Stochastic Dynamic Approach to Tidal Modelling in Estuaries, with an application to the Eastern Scheldt

摘要

A method is presented to predict water levels in tidal estuaries using Kalman filtering techniques. The method is demonstrated by predicting the water levels in the Eastern Scheldt. This estuary appears to contain many of the considerations inherent to modelling flows in estuaries. It is seen that, although the geometry is very complicated by numerous gullies and banks, a very simple schematization suffices. Further, it is shown that nonlinear effects in the mouth due to the complicated geometry and the interaction between the tidal wave along the coast and the water movements in the estuary can be compensated by using stochastic dynamic methods applied to internal boundary conditions.
