Keywords: Water quality modelling coastal ecosystem sediment resuspension hydrodynamic models wave effects microbial contamination
Abstract: Predicting the transport and fate of microbial contaminants in coastal waters, particularly where the movement of sediments can be influenced by hydrodynamic and wave-driven processes, typically relies in the application of computation models. Many hydrodynamic-water quality (HD-WQ) models have been developed and implemented for such applications, often to understand the fate of faecal indicator bacteria (FIB). This systematic review evaluates the suitability of HD-WQ models for simulating coastal water quality, with a specific focus on wave-driven sediment resuspension and FIB dynamics. Using the PRISMA methodology, existing literature are systematically reviewed to compare the capabilities, limitations, and performance characteristics of these different models when simulating wave effects and microbial transport in sediments. Preliminary findings suggest that while some models are extensively validated for coastal hydrodynamics, their integration of wave-sediment-bacteria interactions remain limited. The review will offer recommendations for improving current modelling frameworks and guide future research in coastal microbial water quality modelling.
