Abstract

Shoreline variation along inlet-interrupted coasts in macro-time scales can be addressed as a sediment budget-related process, and it was first presented by Ranasinghe et al. (2013) as the Scale-aggregated Model for Inlet-interrupted Coasts (i.e., SMIC). This was further developed as the Generalised Scale-aggregated Model for Inlet-interrupted Coasts (i.e., G-SMIC) by Bamunawala et al. (2020a, 2020b, 2021). The G-SMIC is a fully probabilistic, generically applicable model that simulates the evolution of inlet-interrupted coasts under climate-change impacts and anthropogenic activities. However, G-SMIC does not consider any ebb-deltas in the vicinity of inlet-estuary systems. Thus, this study aims to include the ebb-delta dynamics into the G-SMIC so that its generic applicability would further increase.
