Hydrocarbon extraction is causing a ground subsidence (sinking) at a rate of 2 mm/yr. The sand size is 0.2 mm, the berm height B is 2 m, and the closure depth h, is 6 m. If no nourishment is carried out, what would be the effect of subsidence on the shoreline position? Quantify any shoreline change rate. What would be the annual nourishment requirement per unit beach length to obtain a stable shoreline?
