LIFE Sparc. Sub report 5. Idealized modelling of FCA and CRT in European estuaries
This report describes a standardized method for setting up and automatically calibrating an idealized numerical model of an estuary that can be used to evaluate the functioning and effectiveness of Flood Control Areas with Controlled Reduced Tide (FCA-CRT). Such models were set up for five European estuaries (Scheldt, Elbe, Seine, Humber, Weser) in order to do a quickscan of the potential of a 100ha FCA-CRT at three different locations along the estuary. The functioning of the areas is evaluated for ecological development inside the areas, and for flood protection along the estuary. The presented method is generally applicable to other estuaries, and has only limited data requirements. The results show that inside the areas, a controlled reduced tide of approximately 15–25% of the estuarine tidal amplitude is achievable with a simple design rule for the culverts. One 100ha FCA also provides a reduction of high water levels during storms in the order of 1-5 cm. This effect extends tens of kilometers up- and downstream the location of the FCA, and is most pronounced when the FCA is located at an upstream location.
