 Abstract

Only in the last 25 years have coastal engineers begun to come to an understanding of the physical processes in and around tidal inlet systems. This lack of knowledge has caused tremendous surprises and problems due to unanticipated reactions of the system to changes caused by human interference. Examples of such interference are: (partial) closure of the tidal basin, dredging of shoals and channels and fixing the inlet gorge by constructing jetties. The system also reacts to changes in the environmental conditions, such as a change in the mean sea level and in wave conditions. In this report we explore the reaction of a tidal inlet system to a number of changes in the conditions. To this end a model is formulated which is partly based on physical processes and partly on empirical formulas. This has to be done because the physics are largely unknown. Hence the word "semi empirical" in the title. In the next chapter, the elements of a tidal inlet system and the sediment transport mechanisms between the elements are described and schematized. Some of the empirical equilibrium parameters are described in Chapter 3. In Chapter 4 the governing ec[uations are formulated. Finally, the model is run and analyzed for four scenarios (partial closure, dredging of tidal flats, sea level rise, and dredging of the ebb tidal delta).
