Abstract In this study, we present a synthetic model summarising the main sedimentary and morphologic factors that drive spatial–temporal variations in bank stability through an exemplar macrotidal estuary. contrast to previous studies tend only consider localised of small‐scale banks, here focus is on understanding patterns at scale whole Severn Estuary (UK). The results show during falling tides, sediments persist near‐saturated state giving elevated pore pressures coincide time with declines hydrostatic confining pressure, leading destabilisation bank. contrast, stabilisation predominantly occurs rising tides when pressure able dominate over processes. Cohesive estuaries similar Estuary, generalised decrease instability moving from outer estuary where tidal oscillations are more significant, inner part system such reduced coupled less high banks.
