(TU Delft Coastal Engineering; Hohai University) Date 2020 Abstract Aggregation is used to represent the real world in a model at an appropriate level of abstraction. We used the convection-diffusion equation toexamine the implications of aggregation progressing from a three-dimensional (3D) spatial description to a model representing a system as asingle box that exchanges sediment with the adjacent environment. We highlight how all models depend on some forms of parametric closure,which need to be chosen to suit the scale of aggregation adopted in the model. All such models are therefore aggregated and make use of someempirical relationships to deal with sub-scale processes. One such appropriately aggregated model, the model for the aggregated scalemorphological interaction between tidal basin and adjacent coast (ASMITA), is examined in more detail and used to illustrate the insight that thislevel of aggregation can bring to a problem by considering how tidal inlets and estuaries are impacted by sea level rise.
