Basic structure of RAPSTA. Y: index of future year from present year, ty: year index in the range [1-Y] in the annual loop, tm: month index in the range [1–12] in the monthly loop, Hs: significant wave height (m), Tp: peak wave period (s), θ: wave direction (°), Hb: breaking wave height (m), θb: breaking wave angle (°), R: riverflow discharge (m3/s), To: ocean tidal range (m), SLR: sea level rise at future year (m), Pt: tidal prism (m3/tidal cycle), P: ebb tidal prism (m3/tidal cycle), M: longshore sediment transport (m3/year), rm: monthly inlet stability criterion, r: annual averaged inlet stability criterion.
